Abstract

We have examined the chromatin structure of a 28-kb chromosomal region containing the gene (CaBP9k) encoding calbindin-D9k in different rat tissues. DNase I-hypersensitive sites (HSs) were probed with DNase I using an indirect end-labeling technique. Duodenal chromatin, where the gene is strongly expressed, contained one major HS (HS4) and three minor HSs (HS2, HS3 and HS5) near the promoter region. The HS4 was mapped just upstream from the promoter region and had the characteristics of a tissue-specific HS. The HS5 was located at the transcription start point, it included the TATA box and its presence was correlated with a promoter function. The duodenal chromatin contained two additional HSs, a major HS (HS1) located approx. 3.5 kb upstream from the cap site and a minor HS (HS6) in the second intron at +0.5 kb. Despite the marked effect of 1,25-dihydroxyvitamin D3 (DHD3) on the CaBP9k mRNA level, the pattern of HSs in duodenal chromatin was unchanged after stimulation with DHD3. The liver chromatin contained one major HS (HS1) identical to the duodenum HS1 (although this tissue does not express CaBP9k). It also contained a liver-specific HS (HS0) 0.1 kb upstream from HS1. The interaction of HS0 with HS1 could explain the abse...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
