Until recently, the methylotrophic yeast was not considered as a potential producer of biofuels, particularly of ethanol from lignocellulosic hydrolysates. The first work published 10 years ago reveals the ability of thermotolerant methylotrophic yeast Hansenula polymorpha to ferment xylose--one of

Although recent genome-wide association studies (GWAS) have been extremely successful, it remains a big challenge to functionally annotate disease‑associated single nucleotide polymorphisms (SNPs), as the majority of these SNPs are located in non‑coding regions of the genome. In this study

RNA helicases are implicated in most cellular RNA-dependent events. In eukaryotes however, only few have been functionally characterized. Upf1 is a RNA helicase essential for nonsense-mediated mRNA decay (NMD). Here, using magnetic tweezers and bulk assays, we observe that human

Peroxynitrite, a product of the reaction of superoxide with nitric oxide, causes oxidative stress with concomitant inactivation of enzymes, poly(ADP-ribosylation), mitochondrial dysfunction and impaired stress signalling, as well as protein nitration. In this study, we sought to determine the effect

Endoplasmic reticulum (ER) stress occurs in poorly perfused tissues and activates the p53 isoform p53/47 to promote G2 arrest via 14-3-3σ. This contrasts with the p21(CDKN1A)-dependent G1 arrest caused by p53 following DNA damage. It is not known how cells

Expressing mspA porin gene from Mycobacterium smegmatis in Mycobacterium tuberculosis attenuated this pathogen. Intracellular growth of the transformants into free-living amoeba and murine and human macrophages decreased. Furthermore, transformants decreased the microbicidal program of human monocyte-derived macrophages. BALB/c mice inoculated

Transcriptional regulation controlled by thyroid hormone receptor (TR) drives events such as development, differentiation, and metabolism. TRs may act either as homodimers or as heterodimers with retinoid X receptor (RXR). Thyroid hormone T3 preferentially binds TR-RXR heterodimers, which activate transcription
