Pyroptosis in acute pancreatitis and its therapeutic regulation.

Apoptosis 2022 Jun 10. Epub 2022 Jun 10.

Molecular Pharmacology Research Center, School of Pharmaceutical Sciences, Wenzhou Medical University, Zhejiang Province, Wenzhou, 325035, China.

Pyroptosis defines a new type of GSDMs-mediated programmed cell death, distinguishes from the classical concepts of apoptosis and necrosis-mediated cell death and is prescribed by cell swelling and membrane denaturation, leading to the extensive secretion of cellular components and low-grade inflammatory response. However, NLRP3 inflammasome activation can trigger its downstream inflammatory cytokines, leading to the activation of pyroptosis-regulated cell death. Current studies reveal that activation of caspase-4/5/11-driven non-canonical inflammasome signaling pathways facilitates the pathogenesis and progression of acute pancreatitis (AP). Read More

Acetic acid triggers cytochrome c release in yeast heterologously expressing human Bax.

Apoptosis 2022 06 1;27(5-6):368-381. Epub 2022 Apr 1.

Centre of Molecular and Environmental Biology (CBMA), Department of Biology, University of Minho, Campus de Gualtar, 4710-057, Braga, Portugal.

Proteins of the Bcl-2 protein family, including pro-apoptotic Bax and anti-apoptotic Bcl-xL, are critical for mitochondrial-mediated apoptosis regulation. Since yeast lacks obvious orthologs of Bcl-2 family members, heterologous expression of these proteins has been used to investigate their molecular and functional aspects. Active Bax is involved in the formation of mitochondrial outer membrane pores, through which cytochrome c (cyt c) is released, triggering a cascade of downstream apoptotic events. Read More

Integrinβ3 mediates the protective effects of soluble receptor for advanced glycation end-products during myocardial ischemia/reperfusion through AKT/STAT3 signaling pathway.

Apoptosis 2022 06 31;27(5-6):354-367. Epub 2022 Mar 31.

Cardiovascular Center, Beijing Tongren Hospital, Capital Medical University, No. 1 Dongjiaomin Lane, Dongcheng District, Beijing, 100730, People's Republic of China.

Soluble receptor for advanced glycation end-product (sRAGE) was reported to protect myocardial ischemia/reperfusion (I/R) injuries via directly interacting with cardiomyocytes besides competing with RAGE for AGEs. However, the specific molecule for the interaction between sRAGE and cardiomyocytes are not clearly defined. Integrins which were reported to interact with RAGE on leukocytes were also expressed on myocardial cells, therefore it was supposed that sRAGE might interact with integrins on cardiomyocytes to protect hearts from ischemia/reperfusion injuries.
