Abstract

Zinc-finger E-box binding homeobox 1 (ZEB1) is an important regulator of epithelial-to-mesenchymal transition and is associated with various types of metastasis. Gastric cancer patients often develop peritoneal carcinomatosis, of which the detection of free cancer cells in the peritoneal washes is an important predictor. We analyzed the correlation of ZEB1 mRNA levels in the peritoneal washing (pZEB1) with clinicopathological variables and survival in 107 gastric cancer patients who underwent surgery and peritoneal washing cytology. Reverse transcription-polymerase chain reaction was performed to quantify pZEB1. The patients were classified into the pZEB1(High) (n=27) and the pZEB1(Low) (n=80) groups based on their pZEB1 expression. pZEB1 was statistically correlated with pathological T stage (P=0.03) and vascular involvement (P=0.03). At 5 years, the disease-specific survival was 36.4% for the pZEB1(High) group and 64.7% for the pZEB1(Low) group (P=0.02), whereas the disease-free survival rate was 46.9% for the pZEB1(High) group and 83.0% for the pZEB1(Low) group (P=0.03). When subclassified into 4 categories based on washing cytology and pZEB1, survival was significantly lower in the pZEB1(High) compared to the pZEB1(Low) gro...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.
