Acetylation of proximal cysteine-lysine pairs by alcohol metabolism.

Alcohol consumption induces hepatocyte damage through complex processes involving oxidative stress and disrupted metabolism. These factors alter proteomic and epigenetic marks, including alcohol-induced protein acetylation, which is a key post-translational modification (PTM) that regulates hepatic metabolism and is associated with the pathogenesis of alcohol-associated liver disease (ALD). Recent evidence suggests lysine acetylation occurs when a proximal cysteine residue is within ∼15 Å of a lysine residue, referred to as a cysteine-lysine (Cys-Lys) pair.

Heterotaxy syndrome, a condition in which the internal organs are abnormally arranged in the thorax or abdomen, is generally diagnosed early in life, often during the neonatal period. We present the case of a 42-year-old male who was incidentally diagnosed with polysplenia syndrome and subsequently diagnosed with heterotaxy syndrome. Upon further investigation, he was determined to have a sinus venosus type atrial septal defect.

Background: Most cases of ovarian hyperstimulation syndrome (OHSS) are caused by infertility treatment using human menopausal gonadotropin (HMG) and human chorionic gonadotropin (hCG). OHSS is widely known to have a "spoke-wheel" appearance on imaging, presenting as bilateral symmetric enlargement of ovaries with multiple cysts of varying sizes. When this spoke-wheel appearance is observed in patients not undergoing infertility treatment, tumor-derived hormones such as follicle-stimulating hormone (FSH) and hCG should be measured.

Objective: To analyze the relationship between Chemokine IP10 and its receptor CXCR3 during prion infection.
Methods: We investigated the increases in IP10 signals, primarily localized in neurons within the brains of scrapie-infected mice, using western blotting, ELISA, co-immunoprecipitation, immunohistochemistry, immunofluorescence assays, and RT-PCR.
Results: Both CXCR3 levels and activation were significantly higher in the brains of scrapie-infected mice and prion-infected SMB-S15 cells.
