Genetic variability in the precore and core promoter regions of hepatitis B virus strains in Karachi [PDF]

BMC Gastroenterology, 2006
Background Hepatitis B virus (HBV) genotypes have distinct geographic distribution. Moreover, much genetic variability has been described in the precore (PC) and basal core promoter (BCP) regions of the HBV genome.

Genetic effect of an InDel in the promoter region of the NUDT15 and its effect on myoblast proliferation in chickens [PDF]

BMC Genomics, 2022
Abstract Background Molecular breeding accelerates the speed of animal breeding. Screening molecular markers that can affect economic traits through genome-wide association studies (GWAS) can provide a theoretical basis for molecular breeding.

Clinical Implications of Genetic Variation in the Serotonin Transporter Promoter Region [PDF]

The Primary Care Companion to The Journal of Clinical Psychiatry, 2009
To determine the state of the art in understanding the role of genetic variation in the serotonin transporter (5-HTT) promoter region (5-HTTLPR) in the development of a depressive episode and in its response to treatment.PubMed and Ovid were used to search for articles published prior to December 2007 utilizing the key words serotonin transporter, 5 ...

Genetic variant in theHSPB1 promoter region impairs the HSP27 stress response [PDF]

Human Mutation, 2007
The 27 kDa heat shock protein 1 (HSP27) is a member of the ubiquitously expressed small heat shock protein family and has pleiotropic cytoprotective functions. Since HSP27 may act as a motor neuron survival factor, we analyzed the genetic contribution of the human HSPB1 gene (HSPB1) to the etiology of amyotrophic lateral sclerosis (ALS). In a cohort of

Genetic analysis of the promoter region of the Bacillus subtilis alpha-amylase gene [PDF]

Journal of Bacteriology, 1989
The amyR2 allele of the Bacillus subtilis alpha-amylase cis-regulatory region enhances production of amylase and transcription of amyE, the structural gene, by two- to threefold over amyR1. The amylase gene bearing each of these alleles was cloned on plasmids of about 10 to 15 copies per chromosome. Transcription of the cloned amylase gene by each amyR

Genetic Variants in the Promoter Region of miR-10b and the Risk of Breast Cancer [PDF]

BioMed Research International, 2017
Variants in microRNA genes may affect their expression by interfering with the microRNA maturation process and may substantially contribute to the risk of breast cancer. Recent studies have identified miR-10b as an interesting candidate because of its close association with the metastatic behavior of breast cancer. However, the roles of miR-10b-related

Characterization of transcriptional enhancers in the chicken genome using CRISPR-mediated activation

Frontiers in Genome Editing, 2023
DNA regulatory elements intricately control when, where, and how genes are activated. Therefore, understanding the function of these elements could unveil the complexity of the genetic regulation network.

Genetic and Epigenetic Alterations of CDH1 Regulatory Regions in Hereditary and Sporadic Gastric Cancer

Pharmaceuticals, 2021
E-cadherin is a key player in gastric cancer (GC) and germline alterations of CDH1, its encoding gene, are responsible for Hereditary Diffuse Gastric Cancer (HDGC) syndrome. This study aimed at elucidating the role of genetic variants and DNA methylation

Functional analysis of recurrent CDC20 promoter variants in human melanoma

Communications Biology, 2023
Small nucleotide variants in non-coding regions of the genome can alter transcriptional regulation, leading to changes in gene expression which can activate oncogenic gene regulatory networks.
