Cis-regulatory elements (CREs) or cis-regulatory modules (CRMs) are regions of non-coding DNA which regulate the transcription of neighboring genes.CREs are vital components of genetic regulatory networks, which in turn control morphogenesis, the development of anatomy, and other aspects of embryonic development, studied in evolutionary developmental biology.
Neurofibromatosis (NF1), also known as Von Recklinghausen disease, is a genetic disorder that is caused by a rare mutation in the neurofibromin gene (NF1) on chromosome 17. [20] This loss of function mutation in the tumor suppressor gene can cause tumors on the nerves called neurofibromas. [21] These appear as small bumps under the skin.
The strict regulation of translation in both space and time is in part governed by cis-regulatory elements located in 5′ mRNA transcript leaders (TLs) and 3′ untranslated regions (UTRs). Due to their role in translation initiation, mRNA 5′ transcript leaders (TLs) strongly influence protein expression.
Eukaryotic genes also contain regulatory sequences beyond the core promoter. These cis-acting control elements bind transcriptional activators or repressors to increase or decrease transcription from the core promoter. Well-characterized regulatory elements include enhancers, silencers, and insulators. These regulatory sequences can be spread ...
Cis-regulatory DNA sequences that are located in DNA regions distant from the promoters of genes can have very large effects on gene expression, with some genes undergoing up to 100-fold increased expression due to such a cis-regulatory sequence. [36] These cis-regulatory sequences include enhancers, silencers, insulators and tethering elements ...

No matter how you slice it, the Chicago Cubs were one of the most disappointing teams of 2024. Improved play in the second half enabled a winning record and a second-place finish in the NL Central ...
