Mechanisms and rationales of SAM homeostasis.

S-Adenosylmethionine (SAM) is the primary methyl donor for numerous cellular methylation reactions. Its central role in methylation and involvement with many pathways link its availability to the regulation of cellular processes, the dysregulation of which can contribute to disease states, such as cancer or neurodegeneration. Emerging evidence indicates that intracellular SAM levels are maintained within an optimal range by a variety of homeostatic mechanisms.

Association of life's essential 8 with prevalence and all-cause mortality of chronic kidney disease among US adults: Results from the National Health and Nutrition Examination Survey (2015-2018).

Background And Objectives: The association between chronic kidney disease (CKD) and cardiovascular disease has been previously evaluated. This study aimed to evaluate the association between the American Heart Association's Life's Essential 8 (LE8) and the prevalence and all-cause mortality of CKD in a nationally representative population of adults in the US.

Methods: This retrospective analysis included participants from the National Health and Nutrition Examination Survey spanning 2015-2018.

Analysis of the therapeutic efficacy of arthroscopic repair of the subscapularis tendon combined with coracoplasty.

The aim of this study was to analyze the outcomes of arthroscopic subscapularis tendon repair combined with coracoplasty in the treatment. The study involved 80 patients (46 males, 34 females; aged 33 to 73 years), who underwent arthroscopic repair for subscapularis tears (type I, II, and III) presenting symptoms of anterior shoulder pain and tenderness. Subcoracoid impingement was defined as a coracohumeral distance of less than 6 mm on preoperative magnetic resonance imaging, with a follow-up of was at least two years.

Dual inhibition of TYK2 and PD-L1 boosts immune response in triple negative breast cancer.

Recent studies have shown that Janus Kinase inhibitors can enhance the tumor therapeutic effect of immune checkpoint inhibitors. However, it remains to be studied whether TYK2 selective inhibitors can enhance the therapeutic effect of small molecule PD-L1 inhibitors in triple-negative breast cancer (TNBC). We verified the efficacy of the combination of the selective TYK2 inhibitor Deucravacitinib and the small molecule inhibitor of PD-L1, INCB086550, in two TNBC animal models: a syngeneic mouse model (4T1 with humanized PD-L1) and a peripheral blood mononuclear cell (PBMC)-humanized model (MDA-MB-231).

Doxazosin Attenuates Development of Testosterone Propionate-induced Prostate Growth by regulating TGF-β/Smad Signaling Pathway, Prostate-specific Antigen Expression and Reversing Epithelial-mesenchymal Transition in Mice and Stroma Cells.

Background: Finasteride and doxazosin are used for the treatment of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS). Epithelial-mesenchymal transition (EMT) plays an important role in BPH, little is known about the growth inhibition and anti-fibrosis effects of doxazosin on the regulation of EMT and morphology in the prostate.

Objectives: The present study examined the effects of doxazosin on testosterone propionate (TP)-induced prostate growth in vivo and in vitro and its impact on the EMT and TGF-β/Smad signaling pathway.
