Abstract

Basic helix‑loop‑helix family member e41 (BHLHE41) serves an important role in regulating cell differentiation, circadian rhythms and the response to hypoxia. However, the roles of BHLHE41 in clear cell renal cell carcinoma (ccRCC) remain unclear. The aim of the present study was to analyze the expression of BHLHE41 in ccRCC and investigate the effect of downregulated BHLHE41 on the growth and migration of ccRCC cells. The expression of BHLHE41 in ccRCC was demonstrated to be significantly increased in gene expression microarray datasets and RNA sequencing data. Reverse transcription‑quantitative polymerase chain reaction and western blot analysis demonstrated that BHLHE41 expression in fresh ccRCC tissues was increased, compared with than their adjacent non‑tumorous controls. BHLHE41 knockdown significantly reduced cell proliferation and migration of A498 and CAKI‑1 cells. For the investigation of the molecules mediated by BHLHE41, immunoblotting analyses revealed that phosphorylation of p70S6K and protein levels of E‑cadherin were reduced. Additionally, a lower frequency methylation was determined in the BHLHE41 3'‑untranslated region through The Cancer Genome Atlas dataset analysis for the first time. These observations demo...Continue Reading

Adenocarcinoma, Clear Cell

Clear Cell Adenocarcinoma is a tumor that arises in the female genital tract and is characterized by cells that appear clear under the microscope. Discover the latest research here.

Adherens Junctions

An adherens junction is defined as a cell junction whose cytoplasmic face is linked to the actin cytoskeleton. They can appear as bands encircling the cell (zonula adherens) or as spots of attachment to the extracellular matrix (adhesion plaques). Adherens junctions uniquely disassemble in uterine epithelial cells to allow the blastocyst to penetrate between epithelial cells. Discover the latest research on adherens junctions here.

Cell Migration

Cell migration is involved in a variety of physiological and pathological processes such as embryonic development, cancer metastasis, blood vessel formation and remoulding, tissue regeneration, immune surveillance and inflammation. Here is the latest research.

Cadherins and Catenins

Cadherins (named for "calcium-dependent adhesion") are a type of cell adhesion molecule (CAM) that is important in the formation of adherens junctions to bind cells with each other. Catenins are a family of proteins found in complexes with cadherin cell adhesion molecules of animal cells: alpha-catenin can bind to β-catenin and can also bind actin. β-catenin binds the cytoplasmic domain of some cadherins. Discover the latest research on cadherins and catenins here.

Carcinoma, Squamous Cell

Basal cell carcinoma is a form of malignant skin cancer found on the head and neck regions and has low rates of metastasis. Discover the latest research on basal cell carcinoma here.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
