Article Abstract

Strong loss-of-function or null mutants can sometimes lead to a penetrant early lethality, impairing the study of these genes' function. This is the case for the null mutant, which exhibits 100% penetrant lethality. Here, we describe how we used gene bashing to identify distinct regulatory regions in the locus. This allowed us to generate a null strain that is viable and still displays mutant Y-to-PDA transdifferentiation phenotype. Such strategy can be applied to many other mutants impacting viability.

Flamenco (Flam) is a prominent Piwi-interacting RNA (piRNA) locus expressed in Drosophila ovarian follicle cells that silences gypsy/mdg4 transposons to ensure female fertility. Promoter-bashing reporter assays in ovarian somatic sheet (OSS) cells uncover compact enhancer sequences within Flam. We confirm the enhancer sequence relevance in vivo with Drosophila Flam deletion mutants that compromise Flam piRNA levels and female fertility.

Article Synopsis
  • The study focuses on a special group of genes called piRNAs that help female animals stay fertile by stopping bad DNA pieces known as transposons from becoming active.
  • Scientists experimented with parts of these genes to learn how they work and found that a protein called Traffic Jam helps control them.
  • By looking at the effects of reducing Traffic Jam, the researchers discovered that it not only affects the piRNAs but also helps prevent problems caused by the transposons.

Gene regulation has been studied in for over 30 years. In this analysis of 102 publications, we find that most transcriptional cis-regulatory elements are located within 5,000 bp of the transcription start site. Over 75% of studies conclude that transcriptional elements and 5'UTRs activate-, while 3'UTRs repress gene expression.

Lung cancer is the world's highest morbidity and mortality of malignant tumors, with lung adenocarcinoma (LUAD) as a major subtype. The competitive endogenous RNA (ceRNA) regulative network provides opportunities to understand the relationships among different molecules, as well as the regulative mechanisms among them in order to investigate the whole transcriptome landscape in cancer pathology. We designed this work to explore the role of a key oncogene, MYC, in the pathogenesis of LUAD, and this study aims to identify important long noncoding RNA (lncRNA)-microRNA (miRNA)- transcription factor (TF) interactions in non-small cell lung cancer (NSCLC) using a bioinformatics analysis.
