Involvement of miR-199a-5p-loaded mesoporous silica nanoparticle-polyethyleneimine-KALA in osteogenic differentiation.

Background/purpose: While there are numerous reports on surgical techniques and materials for bone grafting, limited methods are available to enhance the body's inherent capacity to heal bones. Here we investigated microRNA-199a (miR-199a), a molecular that promotes osteoblast differentiation and bone healing.

Materials And Methods: To construct a miR-199a delivery complex, miR-199a-5p mimics were coated with mesoporous silica nanoparticles (MSNs) following modified with polyethyleneimine (PEI) and peptide WEAKLAKALAKALAKHLAKALAKALKACEA (KALA) to obtain 199a-5p-loaded MSN-PEI-KALA.

Role of increased IGFBP2 in trophoblast cell proliferation and recurrent spontaneous abortion development: A pilot study.

Recurrent spontaneous abortion (RSA) is a serious condition that adversely affects women's health. Differentially expressed proteins (DEPs) in plasma of patients experiencing RSA is helpful to find new therapeutic targets and identified with mass spectrometry. In 57 DEPs, 21 were upregulated and 36 were downregulated in RSA.

HSCs-derived exosomes regulate the levels of inflammatory cytokines in HIBECs through miR-122-5p mediated p38 MAPK signaling pathway.

PBC is an autoimmune-mediated liver disease, and intrahepatic biliary epithelial cells (IBECs) are the target cells of early damage. Previous studies found that miRNAs and inflammation is closely related to PBC. In this study, we extracted exosomes from serum and human IBECs supernatant, and RNA-sequence analyzed the expression profiles of miRNAs.

Bone Marrow Mesenchymal Stem Cells Release miR-378a-5p-Carried Extracellular Vesicles to Alleviate Rheumatoid Arthritis.

This study investigates whether bone marrow mesenchymal stem cell (BMSC)-derived extracellular vesicles (EVs) can affect rheumatoid arthritis (RA) by delivering microRNA (miR)-378a-5p to regulate the interferon regulatory factor 1/signal transducer and transcription 1 (IRF1/STAT1) axis. We identified RA-associated miRNAs using the GEO microarray dataset GSE121894. We found the most important miRNAs in RA synovial tissues using RT-qPCR.

MicroRNA-221-3p Targets THBS1 to Promote Wound Healing in Diabetes.

Introduction: Diabetes foot ulcer (DFU) is a serious complication of diabetes characterized with chronic foot ulceration, poor wound healing (WH), and persistent inflammation. MiR-221-3p, as microRNA, has been shown to accelerate WH in previous study, but the underlying mechanisms are poorly understood.

Methods: In this study, we aimed to determine how miR-221-3p influences WH by targeting THBS1.

Roles of Non-Coding RNAs in Primary Biliary Cholangitis.

Primary biliary cholangitis (PBC) is an autoimmune-mediated chronic cholestatic liver disease, fatigue, and skin itching are the most common clinical symptoms. Its main pathological feature is the progressive damage and destruction of bile duct epithelial cells. Non-coding RNA (NcRNA, mainly including microRNA, long non-coding RNA and circular RNA) plays a role in the pathological and biological processes of various diseases, especially autoimmune diseases.
