Summary: This review provides a comprehensive analysis of the multifaceted role of calcium in apoptosis regulation, focusing on its associated signaling pathways and molecular mechanisms. It explores the impact of calcium on apoptosis through its effects on various cellular compartments and highlights its connection to ER stress. Additionally, it discusses the interplay between calcium and proteins such as calpains, calmodulin, and Bcl-2 family members, and its role in regulating caspase activation and pro-apoptotic factor release. Understanding the complex relationship between calcium and apoptosis is crucial for identifying potential treatment options for diseases associated with imbalanced cell death.

Summary: Apatinib was shown to induce ER stress, autophagy, and apoptosis in ESCC cells, with inhibiting autophagy enhancing apatinib-induced apoptosis. The combination of apatinib and CQ sensitized ESCC cells to paclitaxel through the IRE-1 alpha-AKT-mTOR signaling pathway, suggesting its potential use in innovative anticancer therapeutic strategies.

Summary: The study demonstrated that MCLR induced an increase in Ca2+ concentration in TM4 cells, leading to activation of apoptotic pathways. The use of the Ca2+ chelator Bapta-AM partially reversed MCLR-induced apoptosis, confirming the involvement of calcium homeostasis disruption. Additionally, MCLR activated the ER apoptotic pathway by activating caspase-12.

Summary: The study investigated the effects and underlying mechanisms of valdecoxib on retinal ischemia-reperfusion injury and oxygen-glucose deprivation/recovery injury. The results showed that valdecoxib protected R28 cells by reducing cell apoptosis and exerted a protective effect on retinas by inhibiting retinal ganglion cell apoptosis. In addition, valdecoxib reversed the expression of certain proteins induced by glaucomatous model and the reversal was mediated by the PERK-ATF4-CHOP pathway. These findings suggest that valdecoxib protects against glaucomatous injury by inhibiting ER stress-induced apoptosis via the PERK-ATF4-CHOP pathway.

Summary: This study reveals the mechanisms of silica nanoparticles (SNPs) inducing follicular atresia and apoptosis in granulosa cells. SNPs are found to increase calcium ion concentration in the cytoplasm and activate endoplasmic reticulum (ER) stress. The PERK-ATF4-CHOP-ERO1 alpha pathway plays an essential role in SNP-induced ovarian toxicity, leading to apoptosis via IP3R1-mediated calcium mobilization.

Summary: Angelica gigas has a potent anti-tumor and anti-cancer effect. This study focused on the bioactive compound nodakenin and its effects on breast cancer. Nodakenin was found to inhibit breast cancer cell viability, decrease tumor volume in mice, and induce apoptosis. It also affected signaling pathways and calcium release. Additionally, nodakenin combined with radiation overcame radioresistance in breast cancer cells. These findings suggest nodakenin as a potential therapeutic strategy for breast cancer.

Summary: The study aimed to investigate the mechanism(s) of cisplatin on auditory cells in vitro, focusing on the changes in calcium homeostasis and related channels. Cisplatin induced apoptosis in auditory cells through ER stress and mitochondrial pathway, accompanied by alterations in calcium homeostasis. Interestingly, IP3R dissociation from beclin-1 may play a role in autophagy activation under cisplatin insult.
