Abstract

The binding of androgen-receptor complexes to fragments derived from two alpha 2u-globulin genes (RAP 01 and RAO 01) was studied using a DNA-cellulose competition assay. Rat prostate cytosol labelled with [3H]mibolerone was used as a source of the androgen receptor. Two controls were included in these studies: the long terminal repeat (LTR) of mouse mammary tumor virus which has previously been shown to act as an androgen response element and a fragment of the C3 gene of prostatic binding protein which has been demonstrated to bind androgen-receptor complexes. Our experiments indicate that androgen-receptor complexes bind specifically and with comparable affinity to the C3 gene fragment, the LTR and a fragment of RAP 01 located in the 5'-upstream region (bp -642 up to -584). No specific interaction was observed with fragments derived from RAO 01. The region of RAP 01 which binds androgen-receptor complexes has previously been shown to interact with glucocorticoid receptors and contains a 17 bp sequence homologous with the consensus sequence for glucocorticoid-receptor binding. A mutation in this sequence in RAO 01 may be responsible for the loss of glucocorticoid and androgen-receptor binding. It is concluded that at least one ...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.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

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.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
