METTL3 promotes osteogenesis by regulating N6-methyladenosine-dependent primary processing of hsa-miR-4526.

The function and mechanism of pri-miRNA N6-methyladenosine (m6A) modification in promoting miRNA maturation and regulating osteoblastic differentiation are not fully understood. The aim of this study was to investigate the role and regulatory mechanism of miRNA shear maturation regulated by methyltransferase like 3 (METTL3) in human adipose-derived stem cell (hASC) osteogenesis. Firstly, we found METTL3 promoted osteogenesis both in vivo and in vitro.

The essential roles of mA modification in osteogenesis and common bone diseases.

N6-methyladenosine (mA) is the most prevalent modification in the eukaryotic transcriptome and has a wide range of functions in coding and noncoding RNAs. It affects the fate of the modified RNA, including its stability, splicing, and translation, and plays an important role in post-transcriptional regulation. Bones play a key role in supporting and protecting muscles and other organs, facilitating the movement of the organism, ensuring blood production, .

Detection of the freshness of rice by chemiluminescence.

Reactive oxygen species (ROS) are usually produced in rice under aerobic environmental conditions, resulting in peroxidative changes in polyunsaturated fatty acids, and affecting the deterioration of rice during storage. In addition, as an important enzyme that participates in removing ROS, peroxidase is also present in rice, and takes part in protecting rice from attack by ROS. Moreover, loss of peroxidase activity may give rise to rice deterioration during storage.

Identification of key miRNAs and targeted genes involved in the progression of oral squamous cell carcinoma.

Background/purpose: Oral squamous cell carcinoma (OSCC) is one of the most common types of head and neck squamous cell carcinoma. Accurate biomarkers are needed for early diagnosis and prognosis of OSCC. MicroRNAs (miRNAs) have shown great values in different types of cancers including OSCC.

Synthesis and structure-activity relationship study of new biaryl amide derivatives and their inhibitory effects against hepatitis C virus.

A series of novel biaryl amide derivatives were synthesized and evaluated for anti-HCV virus activity. Some significant SARs were uncovered. The intensive structural modifications led to fifteen novel compounds with more potent inhibitory activity compared to the hit compounds IMB 26 and IMB1f.

Application in photocatalytic degradation of zearalenone based on graphitic carbon nitride.

A semiconductor nano-material was prepared, and its degradation efficiency of zearalenone (ZEN) was studied. The photocatalytic material graphitic carbon nitride (g-C N ) was synthesized by the traditional method of hot cracking. Its structure was characterized by X-ray diffraction (XRD), Fourier-transform infrared (FTIR), X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM) and transmission electron microscopy (TEM).

A pan-cancer analysis of the prognostic and immunological role of β-actin (ACTB) in human cancers.

Beta-actin (ACTB), a highly conserved cytoskeleton structural protein, has been regarded as a common housekeep gene and used as a reference gene for years. However, accumulating evidence indicates that ACTB is abnormally expressed in multiple cancers and hence changes the cytoskeleton to affect the invasiveness and metastasis of tumors. This study aimed to investigate the function and clinical significance of ACTB in pan-cancer.

Synthesis and structure-activity relationship study of water-soluble carbazole sulfonamide derivatives as new anticancer agents.

Here, we formulated and investigated the structure-activity relationships of novel N-substituted carbazole sulfonamide derivatives with improved physicochemical properties. Most of these new compounds displayed good aqueous solubility. Certain molecules presented strong in vitro antiproliferative and in vivo antitumor activity.

Regulation of trichome development in tobacco by JcZFP8, a C2H2 zinc finger protein gene from Jatropha curcas L.

Trichomes are epidermal outgrowths of plant tissues that can secrete or store large quantities of secondary metabolites, which contribute to plant defense responses against stress. The use of bioengineering methods for regulating the development of trichomes and metabolism is a widely researched topic. In the present study, we demonstrate that JcZFP8, a C2H2 zinc finger protein gene from Jatropha curcas L.

The rational search for PDE10A inhibitors from Sophora flavescens roots using pharmacophore‑ and docking‑based virtual screening.

Phosphodiesterase 10A (PDE10A) has been confirmed to be an important target for the treatment of central nervous system (CNS) disorders. The purpose of the present study was to identify PDE10A inhibitors from herbs used in traditional Chinese medicine. Pharmacophore and molecular docking techniques were used to virtually screen the chemical molecule database of Sophora flavescens, a well‑known Chinese herb that has been used for improving mental health and regulating the CNS.
