Cervical cancer is one of the most common types of female malignant tumor. It is well established that radiotherapy (RT) is the first‑line treatment of cervical cancer; however, radioresistance is a substantial obstacle to cervical cancer RT. At present, the mechanism underlying radioresistance remains unclear. Emerging evidence has demonstrated that long non‑coding RNAs (lncRNAs) function as crucial regulators of diverse cancers. Aerobic glycolysis, which is a common phenomenon in cancer cells, is associated with various biological functions, including radioresistance...

Wogonin, a naturally occurring bioactive monoflavonoid isolated from Scutellariae radix (roots of Scutellariae baicalensis Georgi), has known anticancer effects. However, the molecular signaling mechanism by which wogonin inhibits invasiveness in breast cancer cells remains unclear. In the present study, it was observed that wogonin exerted an inhibitory effect on the lipopolysaccharide (LPS)‑enhanced invasiveness of MDA‑MB‑231 cells. In addition, wogonin inhibited the synthesis of interleukin‑8 (IL‑8) and matrix metallopeptidase‑9 (MMP‑9), which are critical for promoting invasiveness in MDA‑MB‑231 cells...

Ubiquitylation of lysine residues in proteins serves a pivotal role in the efficient removal of misfolded or unused proteins and in the control of various regulatory pathways by monitoring protein activity that may lead to protein degradation. The loss of ubiquitylated lysines may affect the ubiquitin‑mediated regulatory network and result in the emergence of novel phenotypes. The present study analyzed mouse ubiquitylation data and orthologous proteins from 62 mammals to identify 193 conserved ubiquitylation sites from 169 proteins that were lost in the Euarchonta lineage leading to humans...

Aerobic glycolysis is one of the characteristics of tumor metabolism and contributes to the development of tumors. Studies have identified that microRNA (miRNA/miR) serves an important role in glucose metabolism of tumors. miR‑199a‑3p is a member of the miR‑199a family that controls the outcomes of cell survival and death processes, and previous studies have indicated that the expression of miR‑199a‑3p is low and may be an inhibitor in several cancer types, including testicular tumors. The present study discussed the role and underlying mechanism of miR‑199a‑3p in aerobic glycolysis of Ntera‑2 cells and identified its downstream factors...

Numerous studies have demonstrated the presence of resident nucleus pulposus stem/progenitor cells (NPSCs) in the tissue of the intervertebral disc (IVD). However, the cellular identity of NPSCs during IVD degeneration and ageing are poorly defined at present, despite significant progress in the understanding of NPSC biology. In the present study, NPSCs were isolated from human degenerated IVD and were characterized by flow cytometry, gene expression assays and proliferation and multipotency analysis. The results of the present study demonstrated that NPSCs isolated from human degenerated IVD may be divided into two groups according to the expression of mesenchymal stem cell (MSC) surface markers: The high expression of MSC surface markers group (H‑NPSCs) was highly positive for CD29, CD44, CD73, CD90 and CD105 at rates >95%, and the low expression of MSC markers surface markers group (L‑NPSCs), with the expression of CD29 and CD105 exhibiting individual variability, however, all at rates <95%...

Stem cell transplantation is a promising clinical strategy for curing ischemic cardiomyopathy. However, its efficacy is impaired by low cell survival following transplantation, partly caused by insufficient resistance of the transplanted stem cells to severe oxidative stress at the injury site. In the current study, it was demonstrated that the small‑molecule macrophage migration inhibitory factor (MIF) enhanced the defense of bone marrow‑derived mesenchymal stem cells (MSCs) against hypoxia/serum deprivation (SD)‑induced apoptosis in vitro...

EpCAM (epithelial cell adhesion molecule) is a type I transmembrane glycoprotein, which was originally identified as a tumor‑associated antigen due to its high expression level in rapidly growing epithelial tumors. Germ line mutations of the human EpCAM gene have been indicated as the cause of congenital tufting enteropathy. Previous studies based on cell models have revealed that EpCAM contributes to various biological processes including cell adhesion, signaling, migration and proliferation. Due to the previous lack of genetic animal models, the in vivo functions of EpCAM remain largely unknown...
