Northwestern Medicine scientists have, for the first time, described the underlying mechanisms that regulate how cells rapidly change gene expression in response to hypoxia, a key feature of many ...

A particularly well studied example of operon repression is the tryptophan (Trp) operon, which, together with the lactose operon, is often used to introduce the subject of operons to college students.

Inducible nitric oxide synthase (iNOS) plays a critical role in inflammatory signaling and tumor immunology, contributing to both pro- and anti-tumor effects depending on the cellular context. While ...

Chronic inducible urticaria (CIndU) is characterized by wheals and/or angioedema (AE) for 6 weeks or more in response to specific and definite triggers. Individual patients can have more than one type ...

The number of known promoters in operons is 1174, while the number of transcription termination sites (TTSs) is only 174 [RegulonDB (12)]. This suggests that, in operons, there are more opportunities ...

Light-inducible regulatory proteins are powerful tools to interrogate fundamental mechanisms driving cellular behavior. In particular, genetically encoded photosensory domains fused to split proteins ...

ABSTRACT: Objective: To investigate the specific mechanism of hypoxia-inducible factor 1 alpha (HIF-1α) in the regulation of human sperm apoptosis, and to provide a new theoretical reference and ...

Introduction: It is estimated that about 40 to 60 million people in the United States suffer from diabetic foot ulcers (DFUs), one of the most severe DM complications. A significant proportion of ...

Some of the most convenient ‘tricks’ on Linux depend on the use of a handful of special characters. This post looks at a number of command operators on Linux and shows how they work. The power of ...
