Article Title: Myotonic dystrophy-related CDC42-binding kinase alpha (MRCKα) mediates methionine- and leucine-stimulated β-casein synthesis in bovine mammary epithelial cells via targeting mTOR

doi: 10.1016/j.aninu.2025.01.003

Figure Lengend Snippet: Silencing of MRCKα inhibits the stimulatory effects of Met and Leu on mRNA abundance of genes related to milk protein synthesis in bovine mammary epithelial cells. Cells were transfected with scrambled siRNA (control, SC) or MRCKα siRNA (SI) and stimulated simultaneously with control (B, basal medium), additional Met (M, Met = 0.6 mM) or Leu (L, Leu = 0.6 mM). After 24 h, cells were collected and isolated for RT-qPCR analysis. Values are presented as mean ± SEM for three independent experiments. P AA , P -value of amino acid addition (AA); P SI , P -value of silencing of MRCKα (SI); P AA×SI , P -value of AA × SI interaction. CSN2 = β-casein; CSN1S1 = αS1-casein; CSN3 = κ-casein; LALBA = lactalbumin α; MRCKα = myotonic dystrophy-related CDC42-binding kinase alpha; mTOR = mechanistic target of rapamycin; JAK2 = Janus kinase 2; STAT5 = signal transducers and activators of transcription 5.

Article Snippet: Rabbit polyclonal anti-human signal transducer and activator of transcription 5 (STAT5) antibody, rabbit polyclonal anti-human phosphorylated STAT5 (Tyr 694 ) antibody, rabbit polyclonal anti-human PI3K antibody and rabbit polyclonal anti-human phosphorylated PI3K (Tyr 317 ) antibody were purchased from Bioss antibodies (Beijing, China).

Article Title: Exercise ameliorates hepatic lipid accumulation via upregulating serum PRL and activating hepatic PRLR-mediated JAK2/STAT5 signaling pathway in NAFLD mice

doi: 10.3389/fphar.2025.1647231

Figure Lengend Snippet: Expression of PRL/PRLR signaling pathway related proteins in liver tissue, and expression levels of PRLR (A) , JAK2 (B) , p-JAK2 (C) , STAT5a (D) , and p-STAT5 (E) in liver tissue of mice in each group.

Article Snippet: The PVDF membrane was blocked with 5% bovine serum albumin (BSA) at room temperature for 1 h and then incubated overnight at 4°C with gentle shaking in the presence of the following primary rabbit monoclonal antibodies: total PRLR (1:500 dilution, ER 1915-43, Huabio), JAK2 (1:1000 dilution, ET1607-35, Huabio), phosphorylated JAK2 (p-JAK2; 1:1000 dilution, ET1607-34, Huabio), STAT5a (1:1000 dilution, ET1610-58, Huabio), phosphorylated STAT5 (p-STAT5; 1:1000 dilution, ET1610-48, Huabio), and β-actin (1:100,000 dilution, AC026, Abclonal).
