Stonewalling Drosophila stem cell differentiation by epigenetic controls

(Submitter supplied) Abstract: During Drosophila oogenesis, germline stem cell (GSC) identity is maintained largely by preventing the expression of factors that promote differentiation. This is accomplished via the activity of several genes acting either in the GSC or its niche. The translational repressors, Nanos and Pumilio, act in GSCs to prevent differentiation, likely by inhibiting translation of early differentiation factors, while niche signals prevent differentiation by silencing transcription of the differentiation factor Bam. more...

Dynamic regulation of alternative splicing and chromatin structure in Drosophila gonads revealed by RNA-seq

(Submitter supplied) Both transcription and post-transcriptional processes, such as alternative splicing, play crucial roles in controlling developmental programs in metazoans. Recently emerged RNA-seq method has brought our understanding of eukaryotic transcriptomes to a new level, because it can resolve both gene expression level and alternative splicing events simultaneously. To gain a better understanding of cellular differentiation in gonads, we analyzed mRNA profiles from Drosophila testes and ovaries using RNA-seq. more...

Defining the Expression of piRNAs and Transposable Elements in Drosophila Ovarian Germline Stem Cells and Niche Cells

(Submitter supplied) Summary: Piwi-interacting RNAs (piRNAs) are important for repressing transposable elements (TEs) and modulating gene expression in germ cells, thereby maintaining genome stability and germ cell function. Here, we show that the canonical piRNA clusters are more active in GSCs (germline stem cells) and their early progeny than late germ cells, and identify new piRNA clusters using deep RNA sequencing. more...

Drosophila YBX1 homolog YPS promotes ovarian germline stem cell development by preferentially recognizing 5-methylcytosine RNAs

(Submitter supplied) 5-Methylcytosine (m5C) is one of the most abundant RNA modifications, but its function in adult stem cell development remains poorly defined. This study shows that Ypsilon schachtel (YPS) promotes germ line stem cell (GSC) maintenance, proliferation, and differentiation in the adult Drosophila ovary by preferentially binding to m5C-containing RNAs. Highly conserved cold-shock domains (CSDs) of YPS and its human homolog Y box binding protein 1 (YBX1) exhibit preferential binding to m5C-containing RNAs through hydrophobic interactions. more...

Aubergine Controls Germline Stem Cell Self-Renewal and Progeny Differentiation via Distinct Mechanisms

(Submitter supplied) Purpose: Piwi family protein Aubergine (Aub) maintains genome integrity in late germ cells of the Drosophila ovary through piRNA-mediated repression of transposon activities. Although it is highly expressed in germline stem cells (GSCs) and early progeny, it remains unclear if it plays any roles in early GSC lineage development. Results: The study reveals a novel function of Aub in GSCs and their progeny, which promotes translation of self-renewal and differentiation factors by directly binding to its target mRNAs and interacting with translational initiation factors.

Whole genome gene expression profiles of migratory cells in the Drosophila ovary

(Submitter supplied) Cell migration contributes to normal development and homeostasis as well as to pathological processes such as inflammation and tumor metastasis. Previous genetic screens have revealed a few major signaling pathways that govern follicle cell migrations in the Drosophila ovary, several of which elicit transcriptional responses. However few downstream targets of the critical transcriptional regulators, such as the C/EBP homolog SLBO, have been identified. more...

Oo-site: A dashboard to visualize gene expression during Drosophila oogenesis reveals meiotic entry is regulated post-transcriptionally

(Submitter supplied) Determining how stem cell differentiation is controlled has important implications for understanding the etiology of degenerative disease and designing regenerative therapies. In vivo analyses of stem cell model systems have revealed regulatory paradigms for stem cell self-renewal and differentiation. The germarium of the female Drosophila gonad, which houses both germline and somatic stem cells, is one such model system. more...

A translation control module coordinates germline stem cell differentiation with ribosome biogenesis during Drosophila oogenesis [bam-aramis double mRNAseq]

(Submitter supplied) Ribosomal defects perturb stem cell differentiation, causing diseases called ribosomopathies. How ribosome levels control stem cell differentiation is not fully known. Here, we discovered three RNA helicases are required for ribosome biogenesis and for Drosophila oogenesis. Loss of these helicases, which we named Aramis, Athos and Porthos, lead to aberrant stabilization of p53, cell cycle arrest and stalled GSC differentiation. more...
