A Matching Strategy To Guide Donor Selection for Ulcerative Colitis in Fecal Microbiota Transplantation: Meta-Analysis and Analytic Hierarchy Process.

Fecal microbiota transplantation (FMT) targeting gut microbiota has recently been applied to the treatment of ulcerative colitis (UC). However, preliminary trials showed that only a subset of patients responded to FMT, and the heterogeneity in donor gut microbiota probably played important roles in patients' responses, implying the significance of matching an appropriate donor to a specified patient. We developed a strategy to build a donor-recipient matching model to guide rational donor selection for UC in FMT.

DKK1 is epigenetically downregulated by promoter methylation and inhibits bile acid-induced gastric intestinal metaplasia.

Dickkopf-related protein 1 (DKK1) is essential to gastric cancer as an inhibitor of Wnt signaling. Gastric intestinal metaplasia (GIM) is an important precancerous lesion of gastric cancer that can be activated by bile acid reflux and chronic inflammation. However, the exact mechanism of DKK1 in bile acid-induced GIM has not been completely elucidated.

Down-regulation of CASC2 contributes to cisplatin resistance in gastric cancer by sponging miR-19a.

Increasing evidence suggests the involvement of long non-coding RNAs (lncRNAs) in chemoresistance of cancer treatment. However, their function and molecular mechanisms in gastric cancer chemoresistance are still not well elucidated. In the present study, we investigate the functional role of lncRNA cancer susceptibility candidate 2 (CASC2) in cisplatin (DDP) resistance of gastric cancer and discover the underlying molecular mechanism.

Intravenous administration of adipose tissue-derived stem cells enhances nerve healing and promotes BDNF expression via the TrkB signaling in a rat stroke model.

Previous studies have shown the beneficial effects of adipose-derived stem cells (ADSCs) transplantation in stroke. However, the molecular mechanism by which transplanted ADSCs promote nerve healing is not yet elucidated. In order to make clear the molecular mechanism for the neuroprotective effects of ADSCs and investigate roles of the BDNF-TrkB signaling in neuroprotection of ADSCs, we, therefore, examined the neurological function, brain water content, and the protein expression in middle cerebral artery occlusion (MCAO) rats with or without ADSCs transplantation.

TRF2 promotes multidrug resistance in gastric cancer cells.

The role of telomere in drug resistance has not been clearly understood. Recent studies have been focused on telomerase activity and telomere length, but the findings are still controversial. It's been found that DNA double-strand breaks induced by anticancer drugs or irradiation increase TRF2 expression as an early response to DNA damage, which inhibits activation of ATM-dependent DNA damage response network, indicating TRF2 might probably be a general DNA-repair factor rather than merely a telomere-binding factor.
