Summary: The study demonstrates that different isoforms of ZAP play overlapping yet different roles in antiviral defense and other cellular processes. The regulation of host mRNA by ZAP is mostly unknown, but splice-switching antisense oligonucleotides can modulate the balance between ZAP isoforms. The study also identifies new cellular transcripts and processes regulated by ZAP isoforms, such as unfolded protein response, epithelial-mesenchymal transition, and innate immunity.

Summary: Ulcerative colitis is a chronic inflammatory disease, and endoplasmic reticular stress-induced autophagy plays a crucial role in its pathogenesis. Dysregulated autophagy can lead to inflammation and disruption of the intestinal barrier, increasing the risk of colonic diseases.

Summary: The study found a correlation between the unfolded protein response (UPR) and hepatocellular carcinoma (HCC) in terms of carcinogenesis, cancer progression, and patient survival. The UPR score can serve as a biomarker for predicting cancer progression and patient prognosis in HCC.

Summary: A growing body of scientific evidence shows that protein homeostasis is linked to chronic diabetic nephropathy (DN). Insulin signaling in podocytes plays a crucial role in maintaining the unfolded protein response (UPR), and defective insulin signaling can lead to maladaptive UPR and DN. Anticoagulant serine protease-activated protein C (aPC) also has a cytoprotective effect in DN. Understanding the molecular mechanisms of adaptive and detrimental responses in renal cells can help develop new therapeutic strategies for DN.

Summary: This review provides an overview of the recent advances in the induction of the integrated stress response (ISR) upon viral infection and the downstream responses, as well as the molecular mechanism of the ISR regulating viral replication and how viruses antagonize this cellular stress response.

Summary: In this study, it was found that exposure to Procymidone (PCM) below the no-observed-effect level causes testicular injury in mice, accompanied by changes in circRNA Scar and circZc3h4 and overactivation of the unfolded protein response (UPR). The use of 4-phenyl butyric acid (4-PBA) can reduce the UPR and protect the testicles. Both in vitro and in vivo experiments showed that 4-PBA can protect the testicles by decreasing PCM-induced circRNA Scar, increasing circZc3h4, and suppressing UPR.

Summary: Azithromycin, a macrolide antibiotic with anti-inflammatory properties, has shown promising treatment potential in reducing inflammation in rheumatoid arthritis patients. It affects signaling cascades associated with cholesterol and lipid biosynthesis, and targets GRP78, playing a key role in anti-arthritic activity.

Summary: This study investigated the role of XBP1, a key regulator of the unfolded protein response (UPR), in the transition from acute kidney injury (AKI) to chronic kidney disease (CKD). The findings demonstrated that XBP1 expression was attenuated after AKI and inversely correlated with the severity of renal fibrosis. XBP1 deficiency in mice resulted in exacerbated renal fibrosis. Silencing XBP1 in human proximal tubular epithelial cells led to cell cycle arrest and increased TGF-beta 1 secretion. The study also identified TNF receptor associated protein 1 (Trap1) as a potential downstream target of XBP1, and showed that Trap1 overexpression alleviated the profibrotic effects of XBP1 deficiency.

Summary: The endoplasmic reticulum is responsible for protein folding, secretion, Ca2+ storage, and lipid synthesis in eukaryotic cells. Disruption to protein folding or Ca2+ homeostasis in the ER leads to what is known as ER stress, triggering the unfolded protein response pathway. Three ER membrane proteins play a crucial role in this process, sensing the accumulation of unfolded/misfolded proteins and activating an integrated transcriptional program.

Summary: This study reveals that statins may affect cellular homeostasis and differentiation in preimplantation embryos by inhibiting the mevalonate pathway. Upregulation of ER stress-responsive genes is influenced differently by inhibition of different geranylgeranylation targets, and may impact trophectoderm lineage specification and blastocyst cavity formation.

Summary: Carfilzomib, a selective proteasome inhibitor, showed potent antiproliferative effects and induced apoptosis in cetuximab-acquired-resistant colorectal cancer cells. This study suggests a potentially novel indication for carfilzomib as an alternative therapeutic agent for cetuximab-resistant colorectal cancer.

Summary: This study demonstrates that iminosugars can inhibit inflammatory responses triggered by viruses, bacteria, and fungi, while reducing the production of inflammatory mediators. By modulating endoplasmic reticulum stress and unfolded protein response, iminosugars may serve as a novel therapeutic approach for sepsis-related inflammatory disorders associated with excessive cytokine secretion.

Summary: Strong evidence supports the role of endoplasmic reticulum stress in ALS pathogenesis, with guanabenz showing promise in reducing neuronal death and prolonging survival through targeting this pathway. A randomized trial showed that higher doses of guanabenz were effective in preventing disease progression, particularly in ALS patients with bulbar onset symptoms. Further research on molecules targeting the unfolded protein response pathway without the side effects of guanabenz is needed for larger trials.
