Downregulation and upregulation. In biochemistry, in the biological context of organisms ' regulation of gene expression and production of gene products, downregulation is the process by which a cell decreases the production and quantities of its cellular components, such as RNA and proteins, in response to an external stimulus.
Up-regulation is a process which occurs within a cell triggered by a signal (originating internal or external to the cell), which results in increased expression of one or more genes and as a result the proteins encoded by those genes. Conversely, down-regulation is a process resulting in decreased gene and corresponding protein expression.
transcriptional regulation – controlling the rate of gene transcription for example by helping or hindering RNA polymerase binding to DNA. transcription – the process of making RNA from a DNA template by RNA polymerase. transcription factor – a substance, such as a protein, that contributes to the cause of a specific biochemical reaction ...
A hurricane center guide describes the damage from a Category 3 storm as “devastating,” with extensive wind and flying debris capable of destroying “nearly all” mobile homes.
She has called for a "first-ever" tax credit for builders of homes sold to first-time buyers, as well as up to $25,000 in down-payment assistance for "eligible" first-time buyers.
The regulatory T cells (Tregs / ˈtiːrɛɡ / or T reg cells), formerly known as suppressor T cells, are a subpopulation of T cells that modulate the immune system, maintain tolerance to self-antigens, and prevent autoimmune disease. T reg cells are immunosuppressive and generally suppress or downregulate induction and proliferation of effector ...
Voltage regulation. In electrical engineering, particularly power engineering, voltage regulation is a measure of change in the voltage magnitude between the sending and receiving end of a component, such as a transmission or distribution line. Voltage regulation describes the ability of a system to provide near constant voltage over a wide ...
Functionally, emotion regulation can also refer to processes such as the tendency to focus one's attention to a task and the ability to suppress inappropriate behavior under instruction. Emotion regulation is a highly significant function in human life. Every day, people are continually exposed to a wide variety of potentially arousing stimuli.
