Cytochrome oxidase is the terminal electron acceptor of the mitochondrial respiratory chain. It is responsible for the vast majority of oxygen consumption in the body and essential for the efficient generation of cellular ATP. The enzyme contains four redox active metal centres; one of these, the binuclear CuA centre, has a strong absorbance in the near-infrared that enables it to be detectable...

A number of non-canonical amino acids (NCAAs) with unstrained olefins are genetically encoded using mutant pyrrolysyl-tRNA synthetase-tRNA(Pyl)(CUA) pairs. These NCAAs readily undergo inverse electron-demand Diels-Alder cycloadditions with tetrazine dyes, leading to selective labeling of proteins bearing these NCAAs in live cells.

Dietary copper (Cu) restriction leads to cardiac hypertrophy and failure in mice, and Cu repletion (CuR) reverses the hypertrophy and prevents the transition to heart failure. The present study was undertaken to determine changes in myocardial gene expression involved in Cu deficient (CuD) cardiomyopathy and its reversal by CuR. Analysis was performed on three groups of mice: 4-week-old CuD mic...

Background: Mutation of p53 is a frequent event, and mutant exhibits low levels acetylation phosphorylation. This study aimed to investigate the effect histone deacetylase (HDAC) inhibitor, 4-hexylresorcinol (4HR), on phosphorylation carcinoma cells its therapeutic effects in xenograft model. Methods: To determine 4HR p53, western blot analysis was performed using YD-9 YD-15 cells. siRNA used e...

Melanoma is the deadliest form of skin cancer, primarily due to its high metastatic propensity and therapeutic resistance in advanced stages. The frequent inactivation p53 tumour suppressor protein melanomagenesis may predict promising outcomes for activators melanoma therapy. Herein, we aimed investigate antitumor potential p53-activating agent SLMP53-2 against melanoma. Two- three-dimensional...
