Biochemical changes and quality characterization of cold-stored 'Sahebi' grape in response to postharvest application of GABA.

In this study, the effect of γ-aminobutyric acid (GABA) at 0 (control), 20 and 40 mM on maintaining postharvest quality, chilling tolerance and fungal decay of 'Sahebi' grapevine (Vitis vinifera L.) was investigated during 60 days storage at 1 °C. GABA-treated fruits especially at 40 mM showed less weight loss (35%), rachis browning (30%) and decay incident (63%) compared to the control.

The cross-talk between signaling pathways, noncoding RNAs and DNA damage response: Emerging players in cancer progression.

The DNA damage response (DDR) pathway's primary purpose is to maintain the genome structure's integrity and stability. A great deal of effort has done to understand the exact molecular mechanisms of non-coding RNAs, such as lncRNA, miRNAs, and circRNAs, in distinct cellular and genomic processes and cancer progression. In this regard, the ncRNAs possible regulatory role in DDR via modulation of key components expression and controlling repair signaling pathway activation is validated.

miR-192 enhances sensitivity of methotrexate drug to MG-63 osteosarcoma cancer cells.

Chemo-resistance remains a considerable obstacle encountered in osteosarcoma (OS) therapy. Evidence has implied that a reduction in the expression of microRNAs (miRs/miRNAs) leads to exacerbated chemo-resistance. Hence, to better understand the role of miR-192 in the pathogenesis of OS during methotrexate (MTX) treatment, we restore miR-192 in the MG-63 cells and investigate the mechanisms, which are associated with MTX-resistance in OS.
