Efficacy of serum-free cultured human umbilical cord mesenchymal stem cells in the treatment of knee osteoarthritis in mice.

Background: We investigated the efficacy of intra-articular injection of human umbilical cord mesenchymal stem cells (hUC-MSCs) for the treatment of osteoarthritis (OA) progression in the knee joint. Although many experimental studies of hUC-MSCs have been published, these studies have mainly used fetal bovine serum-containing cultures of hUC-MSCs; serum-free cultures generally avoid the shortcomings of serum-containing cultures and are not subject to ethical limitations, have a wide range of prospects for clinical application, and provide a basis or animal experimentation for clinical experiments.

Aim: To study the therapeutic effects of serum-free hUC-MSCs (N-hUCMSCs) in a mouse model of knee OA.

A new clinical prognosis model for breast cancer with ADSS as the hub gene.

m6A-related lncRNA-based immune infiltration characteristic analysis and prognostic model for colonic adenocarcinoma.

Background: Colonic adenocarcinoma (COAD) is a common gastrointestinal tract tumor, and its occurrence and progression are typically associated with genomic instability, tumor-suppressor gene and oncogene mutations, and tumor mutational load. N6-methyladenosine (mA) modification of RNAs and long non-coding RNA (lncRNA) expression are important in tumorigenesis and progression. However, the regulatory roles of mA-associated lncRNAs in the tumor microenvironment, stratification of prognosis, and immunotherapy are unclear.

Hypomethylation-driven overexpression of HJURP promotes progression of hepatocellular carcinoma and is associated with poor prognosis.

Our previous studies have initially identified HJURP, which encodes a Holliday junction recognizing protein, as a hepatocellular carcinoma (HCC) susceptibility gene. In this report, we showed that the HJURP is highly expressed in HCC tissues compared to adjacent normal tissues. Overexpression of HJURP in HCC tissues is mainly due to the hypomethylation of HJURP promoter region.

CD11b is involved in coxsackievirus B3-induced viral myocarditis in mice by inducing Th17 cells.

Viral myocarditis (VMC) caused by coxsackievirus B3 (CVB3) infection is a life-threatening disease. The cardiac damage during VMC is not mainly due to the direct cytotoxic effect of the virus on cardiomyocytes but mostly involves the induction of immune responses. Integrin CD11b plays an important role in immune response, for instance, in the induction of Th17 cells.
