Biocatalytic role of cytochrome P450s to produce antibiotics: A review.

Cytochrome P450s belong to a family of heme-binding monooxygenases, which catalyze regio- and stereospecific functionalisation of C-H, C-C, and C-N bonds, including heteroatom oxidation, oxidative C-C bond cleavages, and nitrene transfer. P450s are considered useful biocatalysts for the production of pharmaceutical products, fine chemicals, and bioremediating agents. Despite having tremendous biotechnological potential, being heme-monooxygenases, P450s require either autologous or heterologous redox partner(s) to perform chemical transformations.

Real-time bio-layer interferometry ubiquitination assays as alternatives to western blotting.

Ubiquitination is a crucial cellular pathway enabling normal cellular functions. Abnormalities in the ubiquitination process can lead to cellular dysfunction and cause a range of diseases. Efforts to screen and develop small molecule inhibitors targeting portions of the ubiquitination cascade require rapid and robust methods for detecting ubiquitination.

H19X-encoded miR-322(424)/miR-503 regulates muscle mass by targeting translation initiation factors.

Background: Skeletal muscle atrophy is a debilitating complication of many chronic diseases, disuse conditions, and ageing. Genome-wide gene expression analyses have identified that elevated levels of microRNAs encoded by the H19X locus are among the most significant changes in skeletal muscles in a wide scope of human cachectic conditions. We have previously reported that the H19X locus is important for the establishment of striated muscle fate during embryogenesis.

H19X-encoded miR-424(322)/-503 cluster: emerging roles in cell differentiation, proliferation, plasticity and metabolism.

miR-424(322)/-503 are mammal-specific members of the extended miR-15/107 microRNA family. They form a co-expression network with the imprinted lncRNA H19 in tetrapods. miR-424(322)/-503 regulate fundamental cellular processes including cell cycle, epithelial-to-mesenchymal transition, hypoxia and other stress response.
