Chamuangone from Garcinia cowa leaves inhibits cell proliferation and migration and induces cell apoptosis in human cervical cancer in vitro

Tandem Mass Tag-10plex (TMT-10plex) phosphoproteomics dataset for comprehensive analysis of active compounds with tyrosine kinase inhibition activity

Bioactive compounds derived from natural products demonstrate a wide range of beneficial properties in cancer treatment. One popular approach to inhibiting cancer cell growth is by stimulating apoptosis. Interestingly, our research has discovered that traditional mushroom and isolated compounds from traditional herbs can induce apoptosis in A549 cells while inhibiting tyrosine kinase activities. We have identified two extracts from traditional mushrooms, Phallus indusiatus and Fomes rimosus (Berk.) Cooke, which exhibit promising abilities to activate apoptotic events in cells. Additionally, isolated compounds such as Chamuangone, Cannabigerol (CBG), Cannabidiol (CBD), and NP1-cyclic peptide have also demonstrated significant apoptotic activation capabilities. To further our understanding, we analyzed phosphoprotein changes in A549 cells exposed to these extracts and compounds, both with and without epidermal growth factor (EGF) stimulation. Our positive controls were two known drugs, Afatinib and Osimertinib, which are tyrosine kinase inhibitors with apoptotic stimulation abilities. In order to enrich our understanding of the kinase pathway, we conducted phosphoprotein enrichment analysis and identified altered phosphoproteins using LC-MS/MS. Across these testing conditions, we found that 1228 phosphoproteins were altered, providing valuable insights into the biochemical mechanisms underlying cell apoptosis in A549 cells through post-translational modifications of proteins. Furthermore, our findings not only shed light on the mechanisms of cell apoptosis in A549 cells but also offer promising avenues for future research and therapeutic development.

A Comprehensive Review of the Phytochemical and Pharmacological Potential of an Evergreen Plant Garcinia cowa

Garcinia cowa of the Clusiaceae family, native to South-East Asia used in traditional medicine. It has antipyretic, antimicrobial, and many other biological activities. In this review, a thorough study of this plant's chemical constituents and pharmacological and therapeutic effects was conducted from the research articles from PubMed, Science Direct, Google Scholar, and Scopus from 1977 to 2022. Reported secondary metabolites are enriched with xanthones, phloroglucinols, depsidones, steroids, etc. α-mangostin, β-mangostin, cowaxanthone, rubraxanthone, cowanin, norcowanin, etc. represent the major xanthones. This article discusses the relationship between the different functional groups in xanthone compounds and their bioactivity against cancer, diabetes, bacteria, leishmania, malaria, and inflammation. This review is a comprehensive compendium of major bioactive molecules and its implication for human disease.

A review on the role of epidermal growth factor signaling in the development, progression and treatment of cervical cancer

The sub-committee constituted by the Indian Council of Medical Research (ICMR) for the management of cervical cancer (CC) detailed in the consensus document (2016) reported CC as a significant cause of morbidity and mortality in women. The incidence of an increase in CC and associated mortality in women is a major cause of cancer. To date, human papilloma viral (HPV) infection accounts for more than 99% of CC. However, there are individuals infected with HPV do not develop CC. There is a greater correlation between HPV infection and upregulation of the epidermal growth factor receptor (EGFR) signaling cascade during the initiation, sustenance, and progression of CC. Therefore, EGFR is often targeted to treat CC using tyrosine kinase inhibitors (TKIs) and monoclonal antibodies (mAB). The current review analyzed the existing clinical/pre-clinical studies and the significance of EGFR abundance using the Kaplan-Meier (KM) survival plot analysis for disease-free survival (DFS) and overall survival (OS). We performed a series of bioinformatics analyses to screen the crucial role of the EGFR gene in CC. Further, different transcription factors that are dysregulated due to EGFR abundance and their relevance were determined using computational tools in this review. Endogenous microRNAs (miRNA) that undergo changes due to alterations in EGFR during CC were identified using computational database and consolidated the information obtained with the published in the area of miRNA and EGFR with special reference to the initiation, sustenance and progression of CC. The current review aims to consolidate contemporary approaches for targeting CC using EGFR and highlight the current role of miRNA and genes that are differently regulated during CC involving EGFR mutations. Potential resistance to the available EGFR therapies such as TKIs and mABs and the need for better therapies are also extensively reviewed for the development of newer therapeutic molecules with better efficacy.
