Copper induces hepatic inflammatory responses by activation of MAPKs and NF-κB signalling pathways in the mouse

The present study investigated the expressions of signalling molecules and inflammatory cytokines involved in copper-induced inflammatory responses of the mouse liver. A total of 240 institute of cancer research (ICR) mice (half male and half female) aged four weeks were randomly allocated to four groups treated with 0, 4, 8, and 16 mg/kg of [Cu] (Cu²⁺-CuSO₄) for 42 days, respectively. [Cu] exceeding 4 mg/kg was found to induce inflammatory responses of the liver. Results showed significant up-regulation of mRNA and protein levels of apoptosis signal-regulating kinase 1 (ASK1), mitogen-activated protein kinase kinases 3/6 (MEK3/6), c-Jun N-terminal kinase (JNK), p38 mitogen-activated protein kinase (p38 MAPK), mitogen-activated protein kinase kinases 4/7 (MEK4/7), mitogen-activated protein kinase kinases 1/2 (MEK1/2), and extracellular signal-regulated protein kinases 1/2 (Erk1/2) due to Cu. By doing so, copper could activate the mitogen-activated protein kinases (MAPKs) signalling pathway. Concurrently, the nuclear factor-kappa B (NF-κB) signalling pathway was also activated in the Cu-treatment, as demonstrated by higher expressions of NF-κB and cyclooxygenase-2 (COX-2), activities of inducible nitric oxide synthase (iNOS), contents of nitric oxide (NO) and prostaglandin E2 (PGE2), and reducing levels of expression of inhibitory kappa B (IκB). High Cu intake also up-regulated expression levels of some pro-inflammatory mediators such as interleukin-2 (IL-2), interleukin-1β (IL-1β), and interleukin-8 (IL-8), and down-regulated the levels of expression of transforming growth factor beta (TGF-β), an anti-inflammatory mediator. Additionally, our results indicated that Cu caused hepatic dysfunction, with evidence of occurrence of histopathological lesions and higher serum activities of alkaline phosphatase (AKP), aspartic acid transferase (AST), alanine amino transferase (ALT), and gamma-glutamyl transpeptidase (GGT), contents of albumin (ALB) and total bilirubin (TBIL). Altogether, the aforementioned results indicate that [Cu], at more than 4 mg/kg, induces the inflammatory responses in the liver via NF-κB and MAPKs signalling pathways, subsequently inducing hepatic dysfunction.

Lean and Obese Zucker Rat Extensor Digitorum Longus Muscle high-frequency electrical stimulation (HFES) Data: Regulation of p70S6kinase Associated Proteins

Anaerobic exercise has been advocated as a prescribed treatment for the management of diabetes: however, alterations in exercise-induced signaling remain largely unexplored in the diabetic muscle. Here, we compare the basal and the in situ contraction-induced phosphorylation of the AKT, GSK3beta, mTor, p70s6K, Pten, and Shp2 in the lean and obese (fa/fa) Zucker rat Extensor Digitorum Longus (EDL) muscle following a single bout of contractile stimuli. This article represents data associated with prior publications from our lab (Katta et al., 2009a, 2009b; Tullgren et al., 1991) [1–3] and concurrent Data in Brief articles (Ginjupalli et al., 2017a, 2017b; Rice et al., 2017a, 2017b) [4–7].
