Transformation of acellular dermis matrix with dicalcium phosphate into 3D porous scaffold for bone regeneration.

Animal derived biomaterials have attracted much attentions in treating large size bone defect due to their excellent biocompatibility and potent bioactivities offered by the biomacromolecules and growth factors contained in these materials. Dermis-derived matrix (ADM) has been used as skin grafts and wound dressings for decades, however its application in bone tissue engineering has been largely limited as ADM possesses a dense structure which does not support bone tissue ingrowth. Recently, we have successfully fabricated porous scaffold structure using an ADM with the aid of micronization technique.

Sensing of mycobacterial arabinogalactan by galectin-9 exacerbates mycobacterial infection.

Mycobacterial arabinogalactan (AG) is an essential cell wall component of mycobacteria and a frequent structural and bio-synthetical target for anti-tuberculosis (TB) drug development. Here, we report that mycobacterial AG is recognized by galectin-9 and exacerbates mycobacterial infection. Administration of AG-specific aptamers inhibits cellular infiltration caused by Mycobacterium tuberculosis (Mtb) or Mycobacterium bovis BCG, and moderately increases survival of Mtb-infected mice or Mycobacterium marinum-infected zebrafish.

Targeted and nontargeted metabolomics analysis for determining the effect of storage time on the metabolites and taste quality of keemun black tea.

The black tea could be stored for a long time, and subsequently affects the flavor characteristics. In the present study, the effects of storage years (1, 2, 3, 4, 5, 10, 17 and 20 years) on the chemical profiling and taste quality of keemun black tea (KBT) were compared by metabolomics and quantitative sensory evaluation. The main polyphenols were degraded during the storing, especially 10-year storage, but caffeine and theobromine were stable.

Nuclear mA reader YTHDC1 regulates the scaffold function of LINE1 RNA in mouse ESCs and early embryos.

N-methyladenosine (mA) on chromosome-associated regulatory RNAs (carRNAs), including repeat RNAs, plays important roles in tuning the chromatin state and transcription, but the intrinsic mechanism remains unclear. Here, we report that YTHDC1 plays indispensable roles in the self-renewal and differentiation potency of mouse embryonic stem cells (ESCs), which highly depends on the mA-binding ability. Ythdc1 is required for sufficient rRNA synthesis and repression of the 2-cell (2C) transcriptional program in ESCs, which recapitulates the transcriptome regulation by the LINE1 scaffold.

SIRT1 and gynecological malignancies (Review).

Sirtuin 1 (SIRT1), a member of the sirtuin protein family, is a nicotinamide adenine dinucleotide (NAD)‑dependent type III histone deacetylase and mono‑ADP‑ribosyltransferase. SIRT1 can deacetylate histones (H1, H3, and H4) and non‑histone proteins, and it is widely involved in various physiological and pathological processes in the body, including metabolism, aging, transcription, DNA damage and repair, apoptosis, cell cycle regulation, inflammation and cancer. Research has shown that SIRT1 is involved in tumorigenesis, tumor metastasis and chemotherapy resistance, but it exerts opposing effects and plays different roles in different pathogenic processes.
