Abstract

To clarify the potential effect of long non-coding RNA (lncRNA) TATDN1 on accelerating the proliferative rate and cell cycle progression of hepatocellular carcinoma (HCC) via sponging miRNA-6089, thus participating in the progression of HCC. TATDN1 expression in HCC tissues and normal tissues was first determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The correlation between TATDN1 expression to metastasis and overall survival of HCC was analyzed. The cellular level of TATDN1 in HCC cell lines was examined as well. Regulatory effects of TATDN1 on cell cycle progression and viability of HepG2 and SMMC7721 cells were evaluated. Subsequently, a potential target of TATDN1 was screened out and verified by Dual-Luciferase reporter gene assay. The expression pattern and biological function of the target gene miRNA-6089 in HCC were also determined. In a similar way, LIX1L was verified to be the target of miRNA-6089 and tested for its biological function in HCC. TATDN1 was upregulated in HCC tissues and cell lines. The overexpression of TATDN1 accelerated the proliferative rate and cell cycle progression of HCC. MiRNA-6089, the target gene of TATDN1, was lowly expressed in HCC. The overexpression of miRNA-6089 pa...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.
