Role of asprosin and meteorin-like peptide in progression of actinic keratosis to squamous cell carcinoma.

Squamous cell carcinoma (SCC) often develops from an underlying premalignant lesion. Factors that affect the progression of actinic keratosis (AK) to invasive SCC are not fully known. Asprosin (ASP) and meteorin-like peptide (METRNL) are adipokines that are involved primarily in glucose metabolism.

General guidelines for CRISPR/Cas-based genome editing in plants.

CRISPR (clustered regularly interspaced short palindromic repeats)/Cas (CRISPR-associated) technology is a versatile genome editing tool that has been used to improve agriculturally important plant traits. Due to its precision, CRISPR/Cas9 is more effective than either conventional plant breeding methods or standard genetic engineering approaches for the rapid development of new varieties resilient to climate change. In addition to knowledge in tissue culture-based plant transformation, effective gene-specific single guide RNA (sgRNA) design, prediction of its off-target effect and utilization of vectors, promoters, Cas proteins and terminators is required for CRISPR/Cas9.

A promising independent prognostic biomarker in colorectal cancer: P2X7 receptor.

The P2X7 receptor (P2X7R) is an exclusive member of the purinergic receptor family that plays a key role in tumor progression, including colorectal cancer (CRC). P2X7R supports the tumor cells to resist unfavorable conditions by stimulating GLUT-1 expression. GLUT1 is the major glucose transporter in CRC cells and is indicated to be a poor prognostic indicator in patients with CRC.

P2X7 receptor as an independent prognostic indicator in gastric cancer.

Gastric cancer (GC) is one of the foremost causes of cancer-related death around the world. The P2X7 receptor (P2X7R), a member of the P2X7R subfamily of P2 receptors, is a unique molecule that has been shown to affect tumor growth and progression as well as various inflammatory processes, including proliferation of T lymphocytes, release of cytokines, and production of free oxygen radicals. P2X7R has been established as a prognostic parameter in some cancers, and recently, it has been investigated in the development of new targeted therapies.

Intratumoral Cytotoxic T-Lymphocyte Density and PD-L1 Expression Are Prognostic Biomarkers for Patients with Colorectal Cancer.

Cytotoxic T-lymphocyte (CTL)-mediated inflammatory response to tumors plays a crucial role in preventing the progression of some cancers. Programmed cell death ligand 1 (PD-L1), a cell-surface glycoprotein, has been reported to repress T-cell-mediated immune responses against tumors. However, the clinical significance of PD-L1 in colorectal cancer (CRC) remains unclear.
