Abstract

The Drosophila gonadal (gdl) gene is a member of a gene cluster that maps cytogenetically to the 71CD interval of chromosome 3. The gene is bordered distally by z600, a gene expressed predominantly during early embryogenesis, and proximally by Eip28/29, a gene regulated by ecdysone in Drosophila cell lines. gdl can be expressed in either of two modes in adults: gdlF expression leads to the transcripts 1300 and 1000, which are found in the ovaries, whereas gdlM expression leads to the transcripts 1500 and 1200, which are found in the testes. In situ hybridization analysis reveals that this expression occurs in the germ line during oogenesis and spermatogenesis. Structural studies identify an unusual gdl sequence organization. The ovarian and testes transcripts differ at their 5' ends because of the utilization of different transcription initiation sites. This result indicates that alternative promoter usage is responsible for sex-specific gdl expression. Within an expression mode, the two transcripts differ at their 3' ends as a result of multiple polyadenylation site usage; one of these sites resides within the 5' exon of the Eip28/29 gene. gdl is overlapped by z600 as well because the z600 transcript is polyadenylated at posit...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.
