CD46 Is a Protein Receptor for Human Adenovirus Type 64.

Certain species D human adenoviruses (HAdV-D19, -D37, and -D64) are causative agents of epidemic keratoconjunctivitis. HAdV-D37 has previously been shown to bind CD46 (membrane cofactor protein) and sialic acid as adhesion receptors. HAdV-D64 is genetically highly similar to HAdV-D37, with an identical fiber protein sequence, but differs substantially in its penton base and hexon proteins, two other major capsid components, due to genetic recombination.

Achalasia Quality Indicator Adherence.

Background: Quality indicators (QIs) are formal ways to track health care performance and outcomes, guide quality improvement, and identify gaps in care delivery. We developed twelve quality indicators for achalasia management which cover the domains of patient education, diagnosis, and treatment of achalasia.

Aim: To determine adherence to established quality indicators for achalasia management.

Detection of p53 protein transcriptional activity by chromatin immunoprecipitation.

p53 is a key transcriptional mediator that controls the expression of hundreds of target genes necessary to maintain cellular homeostasis and genome integrity. An important cellular function that is dependent on p53 transcriptional activity is apoptosis or programmed cell death. Indeed, inhibition of p53 transcriptional activity is often observed in cancers as a result of mutations within its DNA-binding domain.

p53 protein aggregation promotes platinum resistance in ovarian cancer.

High-grade serous ovarian carcinoma (HGSOC), the most lethal gynecological cancer, often leads to chemoresistant diseases. The p53 protein is a key transcriptional factor regulating cellular homeostasis. A majority of HGSOCs have inactive p53 because of genetic mutations.
