Objective: To obtain and identify the differential proteome of apoptosis induced by realgar (tetra-arsenic tetra-sulfide, As(4)S(4)) in retinoid acid (RA) resistant human acute promyelocytic leukemia (APL) cell line NB4-R1 cells.
Methods: The comparative proteomic expressive profiles of NB4-R1 cells treated with and without As(4)S(4) were obtained with the high-resolution two-dimensional electrophoresis system. After the analysis of ImageMaster(TM) 2D Platinum software combining artificial comparison. The differential expression proteins were screened and performed in-gel digestion and extraction of peptides, applied mass spectrometry MALDI-TOF-MS, MALDI-TOF/TOF, UPLC-MS/MS and bioinformatics to identify differential expressive proteins.
Results: Twenty-two spots with more than 2-fold (≥ 2 or ≤ 0.5) expression changes were identified and 21 known proteins obtained, including 5 down-regulated (SET/I2PP2A, RPP2, PCBP1, EIF4H-1 and ANP32A/I1PP2A) after exposed to As(4)S(4), 2 up-regulated (HSP27 and HMGB1) after exposed for 24 h, and 14 up-regulated (PHB, ERP29, DNAJC8, PSMB4, ACTB, RPP0, RhoGDI2, alpha-tubulin, transcription factor, RBM15/OTT1, eIF5A1 and H2B1M et al.) after exposed for 48 h.
Conclusion: It is the first time to successfully obtain and identify the global proteome of apoptosis induced by As(4)S(4) in RA-resistant cells. Among them, expressional and functional regulation of target proteins SET, RPP2 and PHB might be the potential novel therapeutic target for RA-resistant APL.

Acute pancreatitis (AP) is a life-threatening condition, with a higher mortality rate in men than women and in which estrogens might play a protective role. This study aimed to investigate sex-dependent differences in a mouse model of caerulein-induced AP. Thirty-six C57BL/6J mice (19 females and 17 males) were treated intraperitoneally with phosphate-buffered saline or caerulein, and sacrificed 12 hours, 2 days, or 7 days after the last injection.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a highly prevalent liver pathology in need of novel pharmacological treatments to complement lifestyle-based interventions. Nuclear receptor agonists have been under scrutiny as potential pharmacological targets and as of today, resmetirom, a thyroid hormone receptor b agonist, is the only approved agent. The dual PPAR α and δ agonist elafibranor has also undergone extensive clinical testing, which reached the phase III clinical trial but failed to demonstrate a beneficial effect on MASLD.

Podophyllotoxin, along with its numerous derivatives and related compounds, is well known for its broad-spectrum pharmacological activity, especially for anticancer potential. In this study, several isatin-podophyllotoxin hybrid compounds were successfully synthesized with good yields through microwave-prompted three-component reactions of 2-amino-1,4-naphthoquinone, various substituted isatins, and tetronic acid. Their cytotoxicity was assessed against four types of human cancer cell lines, HepG2 (hepatoma carcinoma), MCF7 (breast cancer), A549 (non-small lung cancer), and KB (epidermoid carcinoma), alongside nontumorigenic HEK-293 human embryonic kidney cells.

Objectives: Plinabulin, a marine-derived anticancer drug targeting microtubules, exhibits anti-cancer effects on glioblastoma cells. However, its therapeutic potential, specifically for glioblastoma treatment, remains underexplored. This study aims to elucidate the mechanisms by which plinabulin exerts its effects on glioblastoma cells.

Objectives: This study aimed to determine the effect of 8-week high-intensity interval training (HIIT) on oxidative stress and apoptosis in the hippocampus of male rats with type 2 diabetes (T2D). The study focused on examining the role of proliferator-activated receptor gamma co-activator 1α (PGC1α)/Kelch-like ECH-associated protein Keap1/nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway.
Materials And Methods: Twenty-eight 8-week-old Wistar rats were randomly assigned to one of four groups (n=7): control (Con), type 2 diabetes (T2D), exercise (Ex), and exercise + type 2 diabetes (Ex+T2D).
