Ischemic stroke (IS) is the predominant subtype of stroke and a leading contributor to global mortality. The mitochondrial-associated endoplasmic reticulum membrane (MAM) is a specialized region that facilitates communication between the endoplasmic reticulum and mitochondria, and has been extensively investigated in the context of neurodegenerative diseases. Nevertheless, its precise involvement in IS remains elusive. This literature review elucidates the intricate involvement of MAM in mitophagy and endoplasmic reticulum stress during IS. PINK1, FUNDC1, Beclin1, and Mfn2 are highly concentrated in the MAM and play a crucial role in regulating mitochondrial autophagy. GRP78, IRE1, PERK, and Sig-1R participate in the unfolded protein response (UPR) within the MAM, regulating endoplasmic reticulum stress during IS. Hence, the diverse molecules on MAM operate independently and interact with each other, collectively contributing to the pathogenesis of IS as the covert orchestrator.

Background/aims: Endoplasmic reticulum (ER) stress in hepatocytes plays a causative role in alcohol-associated liver disease (ALD). The incomplete inhibition of ER stress by targeting canonical ER stress sensor proteins suggests the existence of noncanonical ER stress pathways in ALD pathology. This study aimed to delineate the role of RAB25 in ALD and its regulatory mechanism in noncanonical ER stress pathways.

Porcupine (PORCN) is a membrane-bound O-acyltransferase primarily localized in the endoplasmic reticulum, where it catalyzes the palmitoylation of Wnt proteins-a critical post-translational modification required for their secretion and signal transduction. This lipid modification plays a key role in regulating essential cellular processes such as differentiation, proliferation, migration, and apoptosis. Inhibition of PORCN prevents Wnt palmitoylation, thereby blocking its extracellular transport and downstream signaling, including β-catenin production, which ultimately suppresses aberrant cell growth.

Extensive research has confirmed that omega-3 fatty acids provide cardiovascular protection primarily by activating the G protein-coupled receptor 120 (GPR120) signaling pathway. However, natural activators of this receptor often lack sufficient strength and precision. TUG-891, a recently synthesized selective GPR120 activator, has displayed significant therapeutic potential in multiple disease.

Background: Hyperthermia (HT), while a cancer treatment approach, isn't always effective alone. Therefore, identifying hyperthermia enhancers is crucial. We demonstrated that Mito-TEMPO ([2-[(1-Hydroxy-2,2,6,6-tetramethylpiperidin-4-yl) amino]-2-oxoethyl]-triphenylphosphanium, MT) acts as a potent thermosensitizer, promoting cell death in human cervical cancer (HeLa) cells.

Bromuconazole, a widely used triazole-based pesticide, effectively controls fungal diseases in agriculture. Bromuconazole cause a potential toxic effect to non-target organisms and can have a negative impact on reproductive health in women, due to its long half-life and bioaccumulation ability. This study identifies the cytotoxicity and adverse effects of bromuconazole on trophoblastic cells (HTR-8/SVneo) and human endometrial cells (T HESCs), which are involved in implantation processes.
