Abstract

Prostatic cancer (PCa) is the first common cancer in male, and the prognostic variables are beneficial for clinical trial design and treatment strategies for PCa. This study was performed to identify more potential biomarkers for the prognosis of patients with PCa. The transcriptome data and survival information of a cohort including 498 subjects with PCa were downloaded from TCGA. A total of 4293 differentially expressed genes (DEGs), including 1362 prognosis-related DEGs, were identified in PCa tissues compared with normal tissues. Upregulated genes, including serine/arginine-rich splicing factors (SRSFs; such as SRSF2, SRSF5, SRSF7 and SRSF8), and ubiquitin conjugating enzyme E2 (UBE2) members (such as UBE2D2, UBE2G2, UBE2J1 and UBE2E1), were identified as negative prognostic biomarkers of PCa, as the high expression of them correlated with poor overall survival of PCa patients. Several downregulated Golgi-ER traffic mediators (such as SEC31A, TMED2, and TMED10) were identified as positive prognostic biomarkers of PCa, as the high expression of them correlated with good overall survival of PCa patients. These genes were of great interests in prognosis of PCa, and some of them may be constructive for the augmentation of clini...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.
