Abstract
One of the most prevalent and deadly types of cancer is breast cancer. The value and effectiveness of the current pharmacological therapy are, however, constrained. Using computational methods and publicly available data, the current study set out to identify the genes and molecular pathways linked to breast cancer. It also looked into potential treatments for the disease that would target these molecular processes. In this study, we mined genes that were strongly associated with breast cancer using text mining and GeneCodis. Using STRING and Cytoscape, protein-protein interaction (PPI) study was carried out. Candidate medications were then derived based on the drug-gene interaction study of the final genes. 2,658 genes linked to breast cancer were found by our investigation using text mining searches. Out of which 166 genes have been taken which are relevant to breast cancer. Ten genes representing ten pathways—which a total of ten proteins could target—were found by gene enrichment analysis. We have taken Holy Basil as our lead as it contains various bioactive compounds such as flavonoids, terpenoids, and phenolics, which have shown antioxidant, anti-inflammatory, and anticancer properties. For this analysis we choose the molecular docking technique to check the effects of different chemical constituents of Holy Tulsi on breast cancer targeted protein and compare their results. We’ve performed the molecular docking in between chemical constituents of Holy Basil and the targeted proteins and determined the binding affinity with the help of PyRx and BIOVIA Discovery studio software. Anti-mitotic activity of Pisum sativum using tulsi extract to check the cytotoxicity effect was done. To determine the toxicity level of the extract on rat liver was performed in the end. In conclusion, investigating candidate medications that target the genes/pathways relevant to breast cancer in order to uncover possible treatments may be accomplished through drug discovery employing in silico text mining and pathway analysis technologies along with the wet lab experimentation with plants and preclinicals.

Introduction

One of the most prevalent malignancies in women globally, breast cancer claimed around 570,000 lives in 2015. Worldwide, more than 1.5 million women (or 25% of all women with cancer) receive a breast cancer diagnosis each year. According to estimates, breast cancer accounted for 30% of all new cancer diagnoses (252,710) among women in the United States in 2017. Breast cancer is incurable mostly because it is a metastatic cancer that frequently spreads to distant organs such the liver, brain, lung, and bone. A favourable prognosis and a high chance of survival can result from early detection of the illness. As the early identification of breast cancer, the 5-year relative survival rate for patients in North America is above 80%. In order to detect breast cancer, mammography is a commonly used screening method that has been shown to effectively lower mortality [1]. In the last ten years, additional screening techniques have also been used and researched, such as Magnetic Resonance Imaging (MRI), which is more sensitive than mammography. Many variables can raise the risk of breast cancer, including sex, aging, estrogen, family history, gene mutations, and an unhealthy lifestyle. The majority of incidences of breast cancer occur in women, who also account for 100 times more cases than males do. Despite the fact that breast cancer is becoming more common in America, fewer people die from the disease as a result of broad early detection programs and cutting-edge medical treatments. Recent developments in biological therapy have shown promise in treating breast cancer [2].
The choice of a suitable treatment to optimize function preservation and reduce the risk of recurrence and metastasis remains difficult in light of the rising incidence of breast cancer and rising patient expectations in recent years. Surgical excision is often regarded as the gold standard in the clinic for treating breast cancer [3]. When treating late-stage breast cancer, non-surgical methods such as photodynamic therapy (PDT), radiation treatment, cryotherapy, and chemotherapy are frequently employed. Nonetheless, there is still a dearth of study on medication therapy, and more investigation is required to support the creation of new therapeutic approaches [4].
Drug repositioning may expedite the process of discovering additional conditions that existing drugs could treat more effectively and potentially at a lower cost, even though the efficacy of the currently available drug therapies is limited and the discovery of new drug therapies using traditional methods is likely to take a long time [5]. Using computational methods such as text mining, biological process and pathway analysis, protein-protein interaction (PPI) analysis to mine public databases, and bioinformatics tools to systematically identify interaction networks between drugs and gene targets, this study aimed to investigate new drug therapies for breast cancer. For the purpose of choosing a medicine, we were able to examine the features of potential genes utilizing data analytical methods [6]. Based on the final genes’ drug-gene interaction analysis, candidate drugs were then derived.
The field of network pharmacology encompasses systems biology, network analysis, connection, redundancy, and pleiotropy in its drug design methodology. A new way of approaching drug discovery is provided by network pharmacology, which simultaneously incorporates efforts to increase clinical efficacy and comprehend toxicity and side effects, two of the main causes of failure. Network research have been seen in a very effective discovery analysis in discovering the biological science. Numerous research have demonstrated the effectiveness of network [7,8].
Furthermore, synthetic behaviours, combinations, and molecular biology probes have been used to identify emergent phenotypes beyond those reported in single-gene deletion investigations [9]. Although there is a strong biological case for multitarget tactics to be preferred over single-target approaches, the pharmaceutical industry currently employs few multitarget strategies [10].
Fast, iterative structure-based drug discovery required advancements in virtual screening, computational processing capacity, high-power radiation sources, refinement methods, compute graphics, and cryocrystallography [11]. It will be necessary to improve a separate set of tools, which deal with combinatorial and network search algorithms and techniques for biological profile prediction, before network pharmacology becomes widely used. The notion that comprehending the drug’s biological and kinetic profile is more significant than validating specific targets or combinations of targets is one that network pharmacology brings back [12].
Large datasets are regularly gathered, saved, and analyzed in the big data era in order to support scientific discoveries and verify theories in the field of biomedicine. Without a question, the introduction of new technologies and open data efforts has resulted in a significant rise in data volume and diversity [13]. Big data are employed in every step of the drug development process, from finding new leads and therapeutic candidates to identifying targets and mechanisms of action. The purpose of illustrating and discussing these approaches is to give an overview of the many databases and computational tools that are available [14]. We believe that personalized care and cost-effectiveness are the two main goals of big data leveraging. To address this, we suggest utilizing information technologies in conjunction with (chemo)informatic tools, leveraging their complementary abilities. Identification of a potential target for the treatment is the first step in the drug discovery process [15]. This could be a specific protein or molecule that is involved in the disease or condition that the drug is intended to treat. Identifying a potential target for a drug is an important step in the drug discovery and development process. Chemoinformatic technologies have the potential to significantly progress in silico drug design and discovery by facilitating multi-level information integration that improves the accuracy of data results [16].
To name a few, chemical structure similarity searching, data mining/machine learning, gene ontology and enrichment analysis, STRING database for protein-protein interaction, Cytoscape have been routinely and successfully implemented [17,18].
In silico study using Pyrx and open Babel software was used to observe targets and binding affinity. It is helpful in virtual screening of libraries of compounds against potential drug targets. [19,20]
To understand and study the genetic pattern of an individual DNA molecule or chromosomes. To determine the mitotic activity of Pisum sativum and the effect of tulsi extract on it, the cytotoxicity test has been performed [21,22].
At the end, the liver toxicity of rats using the extract has been determined to evaluate any liver damage due to the extract [23].

Materials and Methods

Text mining: Text mining enables the automatic collection of disease-gene correlations from extensive biological literature. The UniProt Knowledgebase (UniProtKB) integrates the unreviewed UniProtKB/TrEMBL entries, annotated by automatic methods, such as our rule-based systems, with the reviewed UniProtKB/Switzerland-Prot entries, to which data have been contributed by researchers [19,20]. Of the over 120 million entries in UniProtKB/TrEMBL, the majority are the results of large-scale sequencing operations. For data exploration, UniProt creates connections between genes and the literature. This implies that when queries are run, all the genes from the accessible biological literature that are relevant to the search terms are extracted. We used the idea of “breast cancer” in our inquiry in this investigation [20,21,22]. After selecting “Ensembl Gene ID” and “Associated Gene Name” under GENE, we decided to use “Homo sapiens” as the species dataset. We chose to “search for UniProt genomics” after typing “breast cancer” into the search box, and then we clicked “download” from the top choices. The query then yielded all of the gene hits that were utilized for the following action [23,24,25].
Examination of biological pathways and processes: An essential tool for the biological interpretation of high-throughput experiments, GeneCodis (http://genecodis.cnb.csic.es/) is a web-based tool that combines multiple information sources to search for annotations that frequently co-occur in a group of genes and rank them by statistical significance [26].
We conducted an enrichment analysis of the genes linked to cSCC using GeneCodis. The genes from the text mining step were added to the input set, and the GO biological process categories were used to analyze this gene set. The biological processes that showed the greatest enrichment were chosen [27,28]. The second phase involved using the genes with the chosen annotations for an additional GeneCodis analysis using the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways’ annotations. The pathways that were most pertinent to the pathophysiology of cSCC were chosen among those that were highly enriched above the P-value limit. Genes associated with the chosen pathways were employed in additional analysis [29,30,31].
Network for protein-protein interaction: The protein-protein interactions of certain genes are integrated in the STRING database (http://string-db.org). We entered the genes we had chosen in the previous stage, chose “Homo sapiens” as the organism, and chose “Multiple proteins” from the left menu bar on the STRING database’s first page. In terms of the confidence score, larger confidence scores are seen when there is more evidence that two proteins interact with one another [32,33,34]. Nonetheless, the study’s confidence level was set at medium (score 0.400), even though a lower score would make the network less confident given that it might widen the inclusion criteria. Next, the target genes’ protein-protein interaction network was discovered [35,36].
Identifying targets by acknowledging the degree & betweenness: Next, we visualized and analyzed the interaction network using the Cytoscape software platform. A software program called Cytoscape allows users to visually explore biological networks made up of genes, proteins, and other sorts of interactions [37,38]. The tool is backed by a variety of annotations and experimental data. We imported data from the STRING EXPORT channel in the “.tsv” format. After that, the topological features of every node were examined and the key nodes were chosen using CentiScaPe, an application that computes a greater variety of network parameters [39,40,41]. To choose the important genes, we used “Degree and “Betweenness” as a criterion. Greater gene products that interact with one another indicate a higher node degree, which increases the node’s contribution to breast cancer. The node’s Betweenness value shows how likely a node is to link to the core of other nodes [42,43]. The nodes for which Degree and Betweenness were both larger than or equal to the mean were designated as important nodes in this study according to the criteria for selecting key genes [44,45].
Molecular docking of the targets and lead compounds: Then, we have started with structure-based virtual screening, structures of the target molecules and small molecules [46]. For downloading the 3D structures we detailed from pubchem, protein data bank. Open Babel is used for converting sdf.Format to pdbqt.Format. Then the ligand and macromolecules are added in Pyrx [47]. Started the docking of each ligand one by one. After the completion of docking, process ‘File saved’ in Csv.Format.xl. Here we have checked the binding affinity between the lead and macromolecules [48,49].
Cytotoxic potential of extract on P. sativum: Seeds were kept in distilled water for 48h to obtain 1-2 cm root length and grown in sprouts maker box. Roots were exposed to the extract for 1 hour. The root tips of length between 1-2 cm were cut from 4-5 peas, and then the tips were taken out from the extract and exposed to carnoy’s fixing solution (3 ethanol. 1 glacial acetic acid, v/v) for 1-2 hours. Root tips were taken out and these were incubated in a hot air oven for 15-20 mins with 6N HCL at 30-40 degree. Then the roots were exposed to carmine dye by discarding the HCL, again incubated for 10 mins. The excess dye was washed with glacial acetic acid. The effect of extract on the root tips were observed under microscope [50,51,52].
Precision-cut liver slice cultures in toxicity testing: Rat was dissected open after cervical dislocation, the liver lobes were removed and transferred to prewarmed kreb’s Ringer HEPES buffer (KRH) (2.5 mμ HEPES, PH 7.4, 118 mμ Nacl, 2.25 mμ Kcl, 2.5 mμ Cacl2, 1.5 mμ KH2PO4, 1.18 mμ MgSO4, 5 mμ beta-hydroxybutyrate, 4.0 mμ glucose). Incubated for 10 mins in a shaker [53,54]. Washed it with KRH for 3 times, again dipped into KRH with 2ml methanol for 30 mins in the shaker. Transferred it to the eppendorf tube and homogenize it with the homogenizer stick [55]. The semi-solid was poured on the slide and smeared on it. It was left to dry in the oven for 10 mins. The slide was again dipped in methanol and freezed for 10 mins [56]. Then taken out from methanol and dipped it in the acridine solution ( 1.2 ml acridine + 50 ml water + 0.5 ml acetic acid). The last part was to wash off the excessive stain with distilled water and the damage was observed under the microscope [57].

Results

Result of text mining: 166 genes were discovered to be connected to breast cancer by text mining searches during the investigation of possible breast cancer treatment options (Figure 1). A total of 166 genes were taken because no duplication were discovered in the genes.
In the (Figure 1), Overall process of data mining has been described. Text mining was utilized in conjunction with UniProtkb to uncover genes linked to breast cancer. Following extraction, GeneCodis was used to examine each gene’s function. Using Cytoscape, the target identification was observed by determining the degree and betweenness of the target proteins, and further enrichment was achieved using protein interaction analysis with STRING. Thus, one can obtain potential genes.
The result from the text mining helped us to analyse the large number of proteomics and genomics from the data, articles, documents and genes associated with disease. With the help of extraction/mining of genes through text mining we found the genes that are linked with breast cancer and were sent for enrichment analysis.
Result of biological process and pathway: All the 166 genes from text mining (Table 1) are pasted in genecodis (Figure 2). In order to identify the most enriched phrases associated with breast cancer pathology, biological processes analysis was initially used in GeneCodis gene enrichment analysis. To ensure that only the most enriched annotations were chosen during this procedure. The analysis of enriched pathway annotations resulted in 1st 10 pathways containing a total of 10 unique genes (Table 2).
Result of protein-protein interaction: The protein-protein interaction of 10 genes that were extracted from the KEGG enrichment analysis were autodetected by STRING database and the nodes and their length between the targets are studied and shown accordingly in (Figure 4).
Result of target identification with degree and betweenness: Here we have identified the targets and candidate genes (Figure 5). We loaded data into Cytoscape in the “.tsv” format from the STRING EXPORT channel. Then, to evaluate each node’s topological characteristics and identify the important nodes, we employed CentiScaPe, a software that computes a greater number of network characteristics, with this the degree and betweenness values of all the proteins were identified (Table 3). The total number of edges occurring to the node is represented by the node degree (Figure 6).
Result of Molecular Docking with the targets and the compounds: 10 Genes that were storted out using various softwares and centiscape were then studied with virtual screening and from which 4 genes were able to dock with 28 chemical constituents of Tulsi and have shown binding affinity. The genes were: MFN1, PDILT, GPC2, ZZZ3. All these 4 candidate genes had shown greater binding affinity with Ursolic acid (compound of Tulsi extract).

Discussion

The most prevalent cancer of the mammary gland, breast cancer has a high rate of metastasis and a fatality rate of over 70% when it spreads. It is well acknowledged that surgical excision is the primary treatment for most cases of breast cancer. There hasn’t been much study done on medications as adjuvant therapy, though [58,59]. After doing a gene set enrichment analysis, we were able to identify 166 target genes in this study, of which 70 genes could potentially be used to treat breast cancer. The carcinogenic process’s genetic modifications affect how cells function, enabling self-sufficiency in growth signals, insensitivity to antigrowth signals, escape from apoptosis, infinite replicative potential, invasion, angiogenesis, and metastasis. These changes are consistent with the enriched biological processes—such as “cell differentiation,” “cell division,” “cell adhesion,” and “signal transduction”—that were found using GeneCodis analysis (Table I) [60,61,62]. The appropriate genes are then exported to the STRING database to check and analyse the protein-protein interaction along with the study of different types of nodes present. The same genes are as well transferred to the Cytoscape to visualize the interaction of targets more flexibly [63,64]. With the targeted gene we came across the degree and betweenness of the genes, which helped us to imply the candidate genes for the further analysis with drugs [65,66,67]. After getting the genes, molecular docking has been performed of those targets with the compounds of Tulsi extract and the compound showing highest binding affinity with the protein was found as lead compound [68,69]. After the network pharmacology, In-vitro cell culture was performed to check the cytotoxicity of the extract, and it was observed that there was no toxic effect of the extract on the plant. Then we moved towards ex-vivo with rat liver. We have checked the toxicity of the extract on the liver slices, and no such damage has been observed with the liver slice cultures [70,71]. With the new approaches of personalised medicine, or mitigated medication, these techniques can show high-yielding measures with which we can help curing breast cancer and prevent it from further spreading [72,73].

Conclusion

1. The proteins that have shown the molecular docking are: MFN1, PLD6, GPC2, ZZZ3.
2. The compound found as the lead was: Ursolic Acid.
3. Cytotoxicity of the extract was found to be: Negative.
4. Liver damage of rat with the extract was found to be: Negative.
From the above network pharmacology and experimental pharmacology with various analytical tools and wet lab synthesis, we came to the conclusion that, with the incidence of breast cancer on the rise and patient expectations rising in recent years, selecting an appropriate treatment to maximize preservation of function and minimize the risk of metastasis and recurrence remains challenging. In the clinic, surgical excision is frequently considered the best course of action for treating breast cancer. Non-surgical techniques like photodynamic therapy (PDT), radiation therapy, cryotherapy, and chemotherapy are commonly used to treat late-stage breast cancer. However, research on pharmaceutical therapy is still lacking, and more studies are needed to help develop novel therapeutic strategies.
Even though the efficacy of the currently available drug therapies is limited, and the discovery of new drug therapies using traditional methods is likely to take a long time, drug repositioning may speed up the process of discovering additional conditions that existing drugs could treat more effectively and potentially at a lower cost. This study aimed to investigate new novel plant based drug therapies for breast cancer by means of computational methods including text mining, biological process and pathway analysis, protein-protein interaction (PPI) analysis to mine public databases, bioinformatics tools and experimental methods with in-vitro and ex-vivo to systematically identify interaction networks between drug-gene targets and finding out the lead, including working with the compounds in wet lab. We were able to use data analytical techniques to look at the characteristics of possible genes and work through plant based models in order to select a medication.
With the help of such experimentations, we can further take the analysis towards the novel drug therapy and treat the genes that can be used as a biomarker in correspondence with the drugs compounded for breast cancer.
