Summary: This study found that non-small cell lung cancer (NSCLC) has developed resistance to the chemotherapeutic drug gemcitabine (GEM), and this resistance is associated with alterations in autophagy. The findings suggest that modulating autophagy could be a promising therapeutic approach for drug-resistant lung cancer.

Summary: Bcl-2 family anti-apoptotic proteins play a significant role in cancer, and finding new molecules targeting these proteins has therapeutic potential. Through virtual screening and experimental validation, IS20 and IS21 were identified as compounds that can inhibit the activity of Bcl-2 family proteins and have anti-proliferative and pro-apoptotic effects on various tumors.

Summary: Mantle cell lymphoma (MCL) is an aggressive non-Hodgkin lymphoma with poor prognosis due to drug resistance. Overexpression of antiapoptotic Bcl-xL and depletion of proapoptotic Bax contribute to acquired resistance to bortezomib (BTZ) in MCL cells. High Bcl-xL and low Bax levels are associated with poor prognosis in MCL patients. Targeting these proteins using BH3 mimetics and Bax activators may be a promising strategy to overcome drug resistance in MCL.

Summary: The high expression of SOCS5 is associated with poor prognosis and resistance to TMZ in GBM. TMZ treatment increases the expression of SOCS5 and induces autophagy, which is mediated by SOCS5. Mechanistically, SOCS5 enhances the transcription of Bcl-2. Knockdown of SOCS5 reduces TMZ chemoresistance in GBM cells by inhibiting Bcl-2-mediated autophagy.

Summary: This study reveals that rapalogs induce non-apoptotic autophagy-dependent cell death in HPV-negative mutTP53 HNSCC via the ULK1 pathway. In a mouse tumor model, RAD001 significantly reduces tumor volume without inducing apoptosis, accompanied by an increase in autophagy levels.

Summary: Wogonin has been shown to alleviate glomerulopathy and podocyte injury in diabetic kidney disease (DKD) by regulating the Bcl-2-mediated crosstalk between autophagy and apoptosis. The study also demonstrated the inhibitory effects of wogonin on cellular damage and apoptosis induced by high glucose, as well as its promotion of autophagy in podocytes.

Summary: This study aimed to identify prognostic autophagy-related genes and lncRNAs for predicting clinical outcomes in head and neck squamous cell carcinoma (HNSCC). Differentially expressed ARGs and AR-lncRNAs were identified, and a high-risk group was found to have significantly shorter overall survival (OS). Additionally, autophagy-related pathways were mainly enriched in the high-risk group.

Summary: The study found that the upregulation of CMA in Bz-resistant MM cells and the inhibition of CMA can sensitize the resistant cells to Bz. The protein levels of LAMP2A, the rate-limiting factor of the CMA pathway, were significantly increased in MM patients resistant to Bz and in the Bz-resistant cell line model. Inhibition of CMA sensitizes Bz-resistant cells to Bz and the combination of CMA inhibition and Bz had a more cytotoxic effect on myeloma cells than Bz alone.

Summary: This study found that paclitaxel induces apoptosis in HNSCC cells by activating the JNK signaling pathway and inhibiting the protein controlling mitochondrial membrane potential. Paclitaxel also activates a series of caspase proteins to promote cell apoptosis. These findings may serve as a mechanistic basis for designing more effective paclitaxel-combining regimens to treat HNSCC.

Summary: miR-143 plays an important role in the sensitivity of prostate cancer cells to abiraterone acetate. Upregulation of miR-143 can enhance the sensitivity of prostate cancer cells to abiraterone acetate, and induce cell apoptosis by inhibiting p-JNK and increasing p-Bcl2 expression.

Summary: Compound 6d, a spiroindoline compound, inhibits CRC growth by acting as an inhibitor of Bcl-2 and inducing caspase 3-mediated intrinsic apoptosis. Caspase 3 activation by compound 6d directly cleaves HDAC6, with cleavage occurring at D1088 in the DMAD-S motif. Compound 6d-induced apoptosis promotes autophagy initiation by disrupting the interaction between Bcl-2 and Beclin 1, resulting in the accumulation of ubiquitinated proteins and reduction of autophagic flux.

Summary: This study found that serum 2-OG levels in cholangiocarcinoma patients are associated with the effectiveness of chemotherapy. Patients with progressive disease showed significantly higher levels of serum 2-OG compared to stable disease and partial response patients. The study also revealed that overexpression of ASPH mimics the effects of 2-OG, and knockdown of ASPH improves chemotherapy. Targeting ASPH enhances the effects of chemotherapy by modulating ATM and ATR, two key regulators of DDRs.
