Resistin-Like Molecule Beta (RELM-ß) Regulates Proliferation of Human Diabetic Nephropathy Mesangial Cells via Mitogen-Activated Protein Kinases (MAPK) Signaling Pathway.

BACKGROUND Resistin-like molecule beta (RELM-ß) has been reported to be associated with diabetic nephropathy (DN). However, the role of RELM-ß in DN is poorly understood. This study was conducted to delineate the underlying mechanisms of action and to investigate the role of RELM-ß in the primitive development of DN via MAPK signaling pathways. MATERIAL AND METHODS Lentivirus-mediated vectors and RNAi technology were used to establish the model of RELM-ß up-regulated and down-regulated expression in human mesangial cells (HMCs). The proliferation of HMCs was detected through CCK-8 method. The cell cycle and cell proliferation of HMCs was detected through flow cytometry. The MAPKs pathway protein activity was detected through Western blotting. RESULTS The HMCs with up-regulated and down-regulated expression of RELM-ß increased or decreased significantly at 2-3 days. The HMCs with high glucose intervention reversed the proliferation inhibition. The HMCs with exogenous glucose or RELM-ß protein intervention partially reversed the cell cycle inhibition. Among the MAPKs pathway, the phosphorylation activity of p38MAPK and JNK increased or decreased and ERK1/2 did not change in the overexpression or inhibition of RELM-ß. The p38 MAPK pathway inhibitor SB202190 significantly inhibited the proliferation of HMCs caused by overexpression of RELM-ß. Up-regulated expression of RELM-b induced the phosphorylation of p38 MAPK, JNK in HMCs and promoted HMCs proliferation and participated in early DN through the MAPKs pathway. CONCLUSIONS The results provide evidence that RELM-b is a potential molecular target for the treatment of DN.

An anionic zeolite-like metal-organic framework (AZMOF) with a Moravia network for organic dye absorption through cation-exchange.

An anionic zeolite-like metal-organic framework (AZMOF) with a twisted partially augmented the net, known as the "Moravia" net, [(CH3)2NH2]6[Sr13(O)3()8(OH)2(H2O)16]·xS (, where S represents non-coordinated solvent molecules, and is the abbreviation of benzo-(1,2;3,4;5,6)-tris-(thiophene-2'-carboxylic acid)), has been solvothermally synthesized and characterized, which possesses an anionic framework and nano-sized sodalite cage. Through cation-exchange, is capable of uptaking large organic cationic dyes including Rhodamine B (RB), Basic Red 2 (BR2), Crystal Violet (CV) and Methylene Blue (MB), amongst which the adsorption capability for RB (up to 545 mg g(-1)), and BR2 (up to 675 mg g(-1)) is the highest for reported absorbants to date.
