Summary: Vinigrol is a natural diterpenoid with a unique chemical structure, and its total synthesis has been a subject of great interest in the past decades. In this study, we conducted a comprehensive functional prediction of Vinigrol using a transcriptome-based strategy and identified its prominent anti-cancer effect. Further investigations revealed the underlying targets and regulatory mechanisms of Vinigrol's anti-cancer function. This study provides insights into the structure-efficacy relationship of Vinigrol and its potential applications in experimental and clinical settings.

Summary: The study found significant associations of BiP, sXBP1, and IRE1 alpha with RMS in all studied types of RMS tumors, compared to normal skeletal muscle tissues. BiP and sXBP1 were associated with all subtypes, while IRE1 alpha was associated with ARMS, PRMS, and ERMS, and cytosolic XBP1 was associated with ARMS and SRMS. These findings suggest possible new targeted therapeutic strategies for RMS.

Summary: Malignant mesothelioma is a rare and aggressive cancer strongly linked to asbestos exposure. With limited therapeutic options, novel approaches are urgently needed. Previous studies have shown the importance of GRP78 in MPM survival, and our research suggests that BOLD-100, a specific modulator of GRP78, inhibits MPM cell growth by inducing cellular stress and cell death.

Summary: Saturated FFAs, such as palmitate, circulating in the body can cause ER stress and insulin resistance. In this study, it was found that palmitate treatment reduced insulin-mediated glucose uptake and ERK phosphorylation in Huh-7 cells, while AKT phosphorylation remained unchanged. Supplementation of oleate alleviated palmitate-induced ER stress but did not affect insulin-mediated glucose uptake or ERK phosphorylation.

Summary: Auxins are plant growth regulators that influence various aspects of plant development. The development of an AID system allows rapid, conditional protein degradation, which has been successfully implemented in Caenorhabditis elegans. Indole-3-acetic acid functions through the IRE-1/XBP-1 branch of the UPR to promote resistance to ER stress, indicating caution is needed when using the AID system to study related processes.

Summary: Therapeutic options and prognostic biomarkers for hormone receptor- or Her2 receptor-negative breast cancers are limited. This study reveals that the sigma-1 receptor is elevated in breast cancer, particularly in the aggressive triple-negative subtype. High SIGMAR1 expression is associated with poor survival outcomes and shorter survival times in ER-Her2- groups. In addition, higher SIGMAR1 levels are related to a higher rate of pathologic complete response in patients receiving neoadjuvant taxane + anthracycline treatment.

Summary: The unfolded protein response (UPR) is crucial for alleviating endoplasmic reticulum (ER) stress and many viruses manipulate the UPR signaling network. In the lytic cycle of Epstein-Barr virus (EBV), the expression of central UPR regulator GRP78 is up-regulated, and knockdown of GRP78 reduces virus particle production. BMLF1 is identified as a key regulator contributing to the activation of the grp78 gene promoter and can trigger the activation of the UPR senor ATF6.

Summary: The deletion of Chop gene in beta cells alleviates ER stress and delays glucose-stimulated insulin secretion, preventing the development of fatty liver disease. This study suggests that targeting Chop in beta cells could be a potential therapeutic strategy for improving insulin secretion and preventing complications in type 2 diabetes.

Summary: The chimeric oncogene AML1-MTG8 interacts with UBC9, suggesting a role in leukemogenesis in (8;21) AML. Overexpression of UBC9 suppressed myeloid differentiation, while UBC9 inhibitor accelerated myeloid differentiation. Therefore, UBC9 may be a promising target for therapy against (8;21) AML.

Summary: Lineage switches in acute leukemia are rare, and the mechanisms behind them are not well understood. This report describes a case of an elderly patient with leukemia where the leukemia transformed from B-cell acute lymphoblastic leukemia (B-ALL) to B- and T-cell mixed phenotype acute leukemia (MPAL) and acute myeloid leukemia (AML) during consecutive induction chemotherapy treatments. The patient's leukemia did not respond well to standard B-ALL chemotherapy and eventually transformed into AML. The study suggests that this case should be classified as lineage switching leukemia rather than multiple simultaneous cancers.

Summary: Inosine monophosphate dehydrogenase (IMPDH) inhibitors have been widely used as immunosuppressants but their antitumor effects remain unproven in clinical practice. This study demonstrated the susceptibility of acute myeloid leukemias (AMLs) with MLL-fusions to IMPDH inhibitors in vitro. Alternate-day administration of IMPDH inhibitors effectively suppressed the development of MLL-AF9-driven AML without compromising immune function. The antileukemia effect of IMPDH inhibitors was attributed to the overactivation of Toll-like receptor (TLR)-TRAF6-NF-kappa B signaling pathway and upregulation of VCAM1 adhesion molecule. Combined treatment with IMPDH inhibitors and TLR1/2 agonist showed a promising inhibitory effect on MLL-fusion AML. These findings provide a rational basis for clinical testing of IMPDH inhibitors against MLL-fusion AMLs and other aggressive tumors with active TLR signaling.

Summary: Cutaneous syncytial myoepithelioma is a rare tumor type characterized by nodular proliferation of oval to spindle-shaped tumor cells. The fusion of genes EWSR1 and PBX3 is commonly found in this type of tumor. We report a case with diagnostic difficulty and atypical immunohistochemical results, which were resolved by fluorescence in situ hybridization study to confirm EWSR1 rearrangement. Differential diagnoses and relevant literature are discussed.

Summary: Adrenomedullin (AM) is a peptide that attenuates intestinal mucosal inflammation and enhances mucosal regeneration by upregulating claudin-4 expression in primary-cultured murine intestinal epithelial cells and a mouse model of colitis. AM also reverses TNF alpha-mediated downregulation of claudin-4 and loss of cell-cell adhesion in a human intestinal epithelial cell line, indicating its potential in enhancing intestinal epithelial integrity.
