Abstract

The aim of this study was to investigate the role of long noncoding ribonucleic acids (lncRNAs) AK024094 in regulating the progression of breast cancer (BCa) and the potential mechanism. Our findings might help to provide a theoretical basis for the targeted therapy of BCa. The relative expression level of lncRNA AK024094 in BCa and adjacent normal tissues was determined by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The prognostic potential of AK024094 in BCa was assessed by the Kaplan-Meier method. Meanwhile, AK024094 level in BCa cell lines was detected by qRT-PCR as well. The regulatory effects of AK024094 on the proliferative, migratory, and invasive abilities of MDA-MB-468 and MCF-7 cells were evaluated by functional assays. The Dual-Luciferase Reporter Gene Assay was applied to verify the binding between AK024094 and miRNA-181a. In addition, the rescue experiments were conducted to uncover the role of AK024094/miRNA-181a in the progression of BCa. AK024094 was significantly upregulated in BCa tissues and cell lines. Compared with BCa patients with low expression of AK024094, the tumor staging of those with a high level of AK024094 was remarkably worse. Meanwhile, the rate of distant metastasis was signifi...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.
