Lung tumor discrimination by deep neural network model CanDo via DNA methylation in bronchial lavage.

Bronchoscopic-assisted discrimination of lung tumors presents challenges, especially in cases with contraindications or inaccessible lesions. Through meta-analysis and validation using the HumanMethylation450 database, this study identified methylation markers for molecular discrimination in lung tumors and designed a sequencing panel. DNA samples from 118 bronchial washing fluid (BWF) specimens underwent enrichment via multiplex PCR before targeted methylation sequencing.

Enhancing alfalfa resistance to Spodoptera herbivory by sequestering microRNA396 expression.

Sequestering microRNA396 by overexpression of MIM396 enhanced alfalfa resistance to Spodoptera litura larvae, which may be due to increased lignin content and enhanced low-molecular weight flavonoids and glucosinolates biosynthesis. Alfalfa (Medicago sativa), the most important leguminous forage crop, suffers from the outbreak of defoliator insects, especially Spodoptera litura, resulting in heavy losses in yield and forage quality. Here, we found that the expression of alfalfa microRNA396 (miR396) precursor genes and mature miR396 was significantly up-regulated in wounding treatment that simulates feeding injury by defoliator insects.
