Abstract Mastitis is a common inflammatory cow mammary infection; that causes significant economic loss in dairy industry. Given the interesting connection between metformin’s anti-inflammatory function and mastitis model induced by LTA in pbMECs, our objective was to prove that metformin was beneficial in suppressing proinflammatory response induced by LTA through modulation of mitogen-activated protein kinase (MAPK) and nuclear factor kappa B (NF-κB) signaling pathways and activation of peroxisome proliferator-activated receptor-γ (PPARγ) in pbMECs. The proliferation of cells and mRNA expression were measured using EdU assay and quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR). Immunoblotting and immunofluorescence analysis were conducted to evaluate the… More >

Abstract The mitogen-activated protein kinase (MAPK) cascade is important in stress signal transduction and plant development. In the present study, we identified a rice (Oryza sativa L.) mutant with reduced fertility, Oryza sativa mitogen-activated protein kinase 6 (osmapk6), which harbored a mutated MAPK gene. Scanning and transmission electron microscopy, quantitative RT-PCR analysis, TUNEL assays, RNA in situ hybridization, longitudinal and transverse histological sectioning, and map-based cloning were performed to characterize the osmapk6 mutant. The gene OsMAPK6 was expressed throughout the plant but predominantly in the microspore mother cells, tapetal cells, and microspores in the anther sac. Compared with the wild type,… More >
