Consequently, ELAVL1 determines death receptors-initiated caspase-8-dependent cell death triggered from stimuli including TNF and TRAIL by regulating basal/stimulated caspase-8 levels. As caspase-8 is a master regulator in cell death and inflammation, these results provide valuable clues for tumor immunotherapy and inflammatory diseases.

(Pubmed Central) - Jul 6, 2023 Sarmentosin-induced autophagy was abolished by the autophagy inhibitors 3-methyladenine, chloroquine, and bafilomycin A1...This study showed sarmentosin stimulated autophagic and caspase-dependent apoptosis in HCC, which required activation of Nrf2 and inhibition of mTOR. Our research supports Nrf2 as a therapeutic target for HCC and sarmentosin as a promising candidate for HCC chemotherapy.
- |||||||||| RNase L acts as a regeneration suppressor (ePoster Stage 5; Poster Hall space (NS Building)) - Mar 4, 2023 - Abstract #ISID2023ISID_434;
Additionally, these responses are not limited to skin but extend to other organs, such as the colon (n=4, p<0.05), suggesting that suppression of regeneration is a fundamental characteristic of epithelial wound healing. Taken together, this work suggests that RNase L functions as a regeneration repressor gene in a functional tradeoff that limits immune hyper-activation during viral infection at the cost of also inhibiting regeneration.

(Pubmed Central) - Jan 21, 2023 Moreover, cancer cells no longer grow by halting the cell cycle at two checkpoints, G0/G1 and G2/M, through the inhibition of NF-κB by ICRN. Besides, improving nephrotoxicity occurring due to cisplatin and inhibiting multidrug resistance are the other applications of this biomaterial.
- |||||||||| Preclinical, Journal: 3-MCPD exposure enhances ovarian fibrosis and reduces oocyte quality in mice. (Pubmed Central) - Nov 18, 2022
Consistent with disrupted ovarian homeostasis, 3-MCPD exposure interfered with mitochondrial function, generated more reactive oxygen species, increased ferrous ion and lipid peroxidation levels, and resulted in decreased oocyte development potential. Collectively, these findings indicated that 3-MCPD exposure induced ovarian inflammation and fibrosis, and caused disorders of mitochondrial function and ferrous ion homeostasis in oocytes, which consequently disturbed follicle maturation and reduced oocyte quality.

We also show that the phosphorylated, caspase-cleaved MST2 is as active as the full-length one, suggesting that caspase-stimulated activity arises through noncatalytic mechanisms. The kinetic analysis presented here establishes a framework for interpreting how signaling events and post-translational modifications contribute to the signaling of MST2 in vivo.
- |||||||||| TA0953/HM06, a Novel RET-specific Inhibitor Effective in Extracranial and CNS Disease Models of NSCLC with RETfusions (Hall C7) - Jun 24, 2022 - Abstract #IASLCWCLC2022IASLC_WCLC_745;
P1/2 TAS0953/HM06 was more effective than selpercatinib at decreasing CNS disease and extending survival, at a dose that produced comparable suppression of tumor growth in extracranial disease models. TAS0953/HM06 represents a promising new therapeutic option for patients with RET fusions including those with brain metastasis and those resistant to first-generation selective RET inhibitors.
- |||||||||| Preclinical, Journal: Gasdermin E mediates photoreceptor damage by all-trans-retinal in the mouse retina. (Pubmed Central) - Apr 30, 2022
Of note, degeneration and caspase-3 activation in photoreceptors were significantly alleviated in Abca4Rdh8Gsdme mice after exposure to light. The results of this study indicate that GSDME is a common causative factor of both photoreceptor pyroptosis and apoptosis arising from atRAL overload, suggesting that repression of GSDME activation may represent a potential treatment of photoreceptor atrophy in dry AMD and STGD1.
- |||||||||| Review, Journal: Anti-Eryptotic Activity of Food-Derived Phytochemicals and Natural Compounds. (Pubmed Central) - Apr 9, 2022
The possible diseases associated with eryptosis are various, including anemia, chronic kidney disease, liver failure, diabetes, hypertension, heart failure, thrombosis, obesity, metabolic syndrome, arthritis, and lupus. This review addresses and collates the existing ex vivo and animal studies on the inhibition of eryptosis by food-derived phytochemicals and natural compounds including phenolic compounds (PC), alkaloids, and other substances that could be a therapeutic and/or co-adjuvant option in eryptotic-driven disorders, especially if they are introduced through the diet.

- |||||||||| Journal: Shigella evades pyroptosis by arginine ADP-riboxanation of caspase-11. (Pubmed Central) - Feb 1, 2022
ADP-riboxanation of caspase-11 paralysed pyroptosis-mediated defence in Shigella-infected mice and mutation of ospC3 stimulated caspase-11- and GSDMD-dependent anti-Shigella humoral immunity, generating a vaccine-like protective effect. Our study establishes ADP-riboxanation of arginine as a bacterial virulence mechanism that prevents LPS-induced pyroptosis.
- |||||||||| Review, Journal: Pyroptotic and non-pyroptotic effector functions of caspase-11. (Pubmed Central) - Oct 27, 2021
Consequently, the existence of sophisticated mechanisms that tightly regulate the specificity and sensitivity of inflammasome pathways provides a fine-tuning balance between adequate immune response and minimal tissue damage. In this review, we summarize effector functions of caspase-11.

- |||||||||| Clinical, Journal: Pristimerin Exacerbates Cellular Injury in Conditionally Reprogrammed Patient-Derived Lung Adenocarcinoma Cells by Aggravating Mitochondrial Impairment and Endoplasmic Reticulum Stress through EphB4/CDC42/N-WASP Signaling. (Pubmed Central) - May 15, 2021
The present study also provides mechanistic evidence that PRIS suppressed the EphB4/CDC42/N-WASP signaling pathway, which is required for mitochondrial-mediated intrinsic apoptosis, activation of ER stress, and stimulation of caspase-4 induced by PRIS, and consequently resulting in suppressed cell viability, migration, and angiogenesis in CRLCs. Taken together, by providing a mechanistic insight into the modulation of ER stress-induced cell death in CRLCs by PRIS, we suggest that PRIS has a strong potential of being a new antitumor therapeutic agent with applications in the fields of human lung adenocarcinoma.
