Comprehensive circRNA expression profile and construction of circRNA-related ceRNA network in cardiac fibrosis.

Cardiac fibrosis is a common pathological condition that contributes to the progression of many cardiac diseases. Circular RNAs (circRNAs) are emerging as new regulators of cardiac fibrosis. However, the expression and function of circRNAs in cardiac fibrosis remain largely unknown.

Advance in the research on super-enhancer.

Super-enhancers (SEs) are large clusters of transcriptional enhancers that drive expression of genes controlling cell identity. They play important roles in development, disease initiation and progression such as tumorigenesis. Compared to typical enhancers (TEs), most key oncogenes in tumor cells are driven by SEs, and common diseases such as Alzheimer's disease related variations are enriched in SEs.

Decreased skin-mediated detoxification contributes to oxidative stress and insulin resistance.

The skin, the body's largest organ, plays an important role in the biotransformation/detoxification and elimination of xenobiotics and endogenous toxic substances, but its role in oxidative stress and insulin resistance is unclear. We investigated the relationship between skin detoxification and oxidative stress/insulin resistance by examining burn-induced changes in nicotinamide degradation. Rats were divided into four groups: sham-operated, sham-nicotinamide, burn, and burn-nicotinamide.

The panorama of physiological responses and gene expression of whole plant of maize inbred line YQ7-96 at the three-leaf stage under water deficit and re-watering.

Changes in water potential, growth elongation, photosynthesis of three-leaf-old seedlings of maize inbred line YQ7-96 under water deficit (WD) for 0.5, 1 and 2 h and re-watering (RW) for 24 h were characterized. Gene expression was analyzed using cDNA microarray covering 11,855 maize unigenes.

An ordered EST catalogue and gene expression profiles of cassava (Manihot esculenta) at key growth stages.

A cDNA library was constructed from the root tissues of cassava variety Huanan 124 at the root bulking stage. A total of 9,600 cDNA clones from the library were sequenced with single-pass from the 5'-terminus to establish a catalogue of expressed sequence tags (ESTs). Assembly of the resulting EST sequences resulted in 2,878 putative unigenes.

Nicotinamide overload may play a role in the development of type 2 diabetes.

Aim: To investigate whether nicotinamide overload plays a role in type 2 diabetes.

Methods: Nicotinamide metabolic patterns of 14 diabetic and 14 non-diabetic subjects were compared using HPLC. Cumulative effects of nicotinamide and N(1)-methylnicotinamide on glucose metabolism, plasma H(2)O(2) levels and tissue nicotinamide adenine dinucleotide (NAD) contents of adult Sprague-Dawley rats were observed.
