p53 Mediates Cellular Dysfunction and Behavioral Abnormalities in Huntington’s Disease

We present evidence for a specific role of p53 in the mitochondria-associated cellular dysfunction and behavioral abnormalities of Huntington's disease (HD). Mutant huntingtin (mHtt) with expanded polyglutamine (polyQ) binds to p53 and upregulates levels of nuclear p53 as well as p53 transcriptional activity in neuronal cultures. The augmentation is specific, as it occurs with mHtt but not muta...

Sperm abnormalities: Adverse effects of thyroid dysfunction

Introduction: Despite the importance of thyroid hormones in reproduction, there are only a few studies that focus on male infertility. The objective of this study was to evaluate semen parameters in patients with hypothyroidism or hyperthyroidism. Materials and methods: Totally, 28 patients with thyroid disorders were evaluated for the semen parameters. Serum TSH and T4 concentrations were mea...

Protein carbonylation, cellular dysfunction, and disease progression

Carbonylation of proteins is an irreversible oxidative damage, often leading to a loss of protein function, which is considered a widespread indicator of severe oxidative damage and disease-derived protein dysfunction. Whereas moderately carbonylated proteins are degraded by the proteasomal system, heavily carbonylated proteins tend to form high-molecular-weight aggregates that are resistant to...
