Molecular Mechanism of Cynodon dactylon Phytosterols Targeting MAPK3 and PARP1 to Combat Epithelial Ovarian Cancer: A Multifaceted Computational Approach

Epithelial Ovarian Cancer (EOC) presents a global health concern, necessitating the development of innovative therapeutic strategies to combat its impact. This study was employed to investigate the unexplored therapeutic efficacy of Cynodon dactylon phytochemicals against EOC using a multifaceted computational approach. A total of 19 out of 89 rigorously curated phytochemicals were assessed as potential drug targets via ADMET profiling, while protein-protein interaction analysis scrutinized the top 20 hub genes among 264 disease targets, revealing their involvement in cancer-related pathways and underscoring their significance in EOC pathogenesis. In molecular docking, Stigmasterol acetate showed the highest binding affinity (-10.9 kcal/mol) with Poly [ADP-ribose] polymerase-1 (PDB: 1UK1), while Arundoin and Beta-Sitosterol exhibited strong affinities (-10.4 kcal/mol and -10.1 kcal/mol, respectively); additionally, Beta-Sitosterol interacting with Mitogen-activated protein kinase 3 (PDB: 4QTB) showed a binding affinity of -10.1 kcal/mol, forming 2 hydrogen bonds and a total of 10 bonds with 10 residues. Molecular dynamics simulations exhibited the significant structural stability of the Beta-Sitosterol-4QTB complex with superior binding free energy (-36.61 kcal/mol) among the three complexes. This study identified C. dactylon phytosterols, particularly Beta-Sitosterol, as effective in targeting MAPK3 and PARP1 to combat EOC, laying the groundwork for further experimental validation and drug development efforts.

Integrative transcriptomics and proteomics analyses to reveal the therapeutic effect and mechanism of Buxue Yimu Pills in medical-induced incomplete abortion rats

ETHNOPHARMACOLOGICAL RELEVANCE

Medical abortions using mifepristone and misoprostol have been approved in many countries for early pregnancy loss. Despite its high success rate, this medication regimen can result in incomplete abortion, which is responsible for endometrial damage, prolonged uterine bleeding, abdominal pain, etc. Buxue Yimu Pills (BYP) is a famous Chinese medicine prescription that is widely used in the field of gynecology and obstetrics for treating patients with postpartum complications. However, the therapeutic effect and mechanism of BYP remain to be explored.

AIM OF THE STUDY

This study aimed to clarify the therapeutic effect and mechanism of action of BYP in postpartum complications using mifepristone and misoprostol-induced incomplete abortion in rats.

MATERIALS AND METHODS

Experimental medical-induced incomplete abortion model rats were constructed using mifepristone and misoprostol, and further treated with saline or BYP by intragastric administration. Detailed information regarding the changes in mRNA and protein levels in the uterine tissues of rats regulated by BYP was illustrated by RNA sequencing (RNA-seq) analysis and quantitative proteomics analysis. The differentially expressed genes and proteins were further subjected to Gene Ontology (GO) and pathway enrichment analyses and further verified using quantitative Real-time PCR (qRT-PCR) analysis and western blot assay.

RESULTS

BYP administration markedly alleviated the increase in serum prostaglandin F2α (PGF2α) and expression of PGF2α receptor (PGF2αR) in uterine tissues and inhibited the decrease in serum chorionic gonadotrophin (CG). Compared with the model group, 674 genes were upregulated and 344 genes were downregulated by BYP administration; 108 proteins were upregulated and 48 proteins were downregulated by BYP administration. qRT-PCR analysis of the uterine tissues showed that BYP treatment reversed the variation tendency of genes, including Mmp7, Mmp14, Timp2, Col6a4, Jak2, Wnt7a, and Mylk compared with the model group. Western blot analysis showed that BYP administration affected PKCδ, Collagen VI, MMP7, TIMP2, MLCK, and p-MLC protein levels.

CONCLUSION

BYP administration facilitated uterine recovery in medical-induced incomplete abortion rats, and this therapeutic effect involved various targets and biological processes, including the TIMP2/MMP7 and MLCK/p-MLC signaling pathways, etc.

Using omics approaches to dissect the therapeutic effects of Chinese herbal medicines on gastrointestinal cancers

Chinese herbal medicines offer a rich source of anti-cancer drugs. Differences between the pharmacology of Chinese herbal medicines and modern synthetic chemicals hinder the development of drugs derived from herbal products. To address this challenge, novel omics approaches including transcriptomics, proteomics, genomics, metabolomics, and microbiomics have been applied to dissect the pharmacological benefits of Chinese herbal medicines in cancer treatments. Numerous Chinese herbal medicines have shown potential anti-tumor effects on different gastrointestinal (GI) cancers while eliminating the side effects associated with conventional cancer therapies. The present study aimed to provide an overview of recent research focusing on Chinese herbal medicines in GI cancer treatment, based on omics approaches. This review also illustrates the potential utility of omics approaches in herbal-derived drug discovery. Omics approaches can precisely and efficiently reveal the key molecular targets and intracellular interaction networks of Chinese herbal medicines in GI cancer treatment. This study summarizes the application of different omics-based approaches in investigating the effects and mechanisms of Chinese herbal medicines in GI cancers. Future research directions are also proposed for this area of study.

TXNIP: A Double-Edged Sword in Disease and Therapeutic Outlook

Thioredoxin-interacting protein (TXNIP) was originally named vitamin D₃ upregulated protein-1 (VDUP1) because of its ability to bind to thioredoxin (TRX) and inhibit TRX function and expression. TXNIP is an alpha-arrestin protein that is essential for redox homeostasis in the human body. TXNIP may act as a double-edged sword in the cell. The balance of TXNIP is crucial. A study has shown that TXNIP can travel between diverse intracellular locations and bind to different proteins to play different roles under oxidative stress. The primary function of TXNIP is to induce apoptosis or pyroptosis under oxidative stress. TXNIP also inhibits proliferation and migration in cancer cells, although TXNIP levels decrease, and function diminishes in various cancers. In this review, we summarized the main structure, binding proteins, pathways, and the role of TXNIP in diseases, aiming to explore the double-edged sword role of TXNIP, and expect it to be helpful for future treatment using TXNIP as a therapeutic target.
