HOW(S) RIP-seq in D. melanogaster testes

ABSTRACT: Held out wings (HOW) is an RNA-binding protein essential for spermatogenesis in Drosophila melanogaster. HOW is a signal transduction and activation of RNA (STAR) protein, these proteins are important post-transcriptional regulators of RNAs. The characteristics of RNA-binding by the conserved short cytoplasmic isoform, HOW(S), are unknown. In vivo RIP-seq identified 121 novel transcripts bound by HOW(S) in spermatogonia, many with signal transduction functions. (A/G/U)CUAAC motifs were enriched in 3'-UTRs and GCG(A/U)G in 5'-UTRs. HOW binds with high-affinity to sites containing the CUAAC motif from lola and hipk mRNAs, but not to GCG(A/U)G 5’-UTR motifs. Overall, this study provides new insight into STAR protein-RNA interactions and potential importance to spermatogenesis.

Cdk1-mediated threonine phosphorylation of Sam68 modulates its RNA binding, alternative splicing activity, and cellular functions

Project description:Sam68 is a member of the STAR family of proteins that directly link signal transduction with post-transcriptional gene regulation. Sam68 controls the alternative splicing of many oncogenic proteins and its role is modulated by post-translational modifications, including serine/threonine phosphorylation, that differ at various stages of the cell cycle. However, the molecular basis and mechanisms of these modulations remain largely unknown. Here, we combined mass spectrometry, NMR spectroscopy, and cell biology techniques to provide a comprehensive post-translational modification (PTM) mapping of Sam68 at different stages of the cell cycle in HEK293 and HCT116 cells. We established that Sam68 is specifically phosphorylated at T33 and T317 by Cdk1, and demonstrated that these phosphorylation events reduce the binding of Sam68 to RNA, control its cellular localization, and reduce its alternative splicing activity, leading to a reduction in the induction of apoptosis and an increase in the proliferation of HCT116 cells.

Project description:modENCODE_submission_5003 This submission comes from a modENCODE project of Kevin White. For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: The White Lab is aiming to map the association of all the Transcription Factors (TF) on the genome of Drosophila melanogaster. One technique that we use for this purpose is chromatin immunoprecipitation coupled with deep sequencing (ChIP-seq) utilizing an Illumina next generation sequencing platform. The data generated by ChIP-seq experiments consist basically of a plot of signal intensity across the genome. The highest signals correspond to positions in the genome occupied by the tested TF. For data usage terms and conditions, please refer to http://www.genome.gov/27528022 and http://www.genome.gov/Pages/Research/ENCODE/ENCODEDataReleasePolicyFinal2008.pdf EXPERIMENT TYPE: CHIP-seq.

Androgen Promotes Differentiation of Promyelocytic Leukemia Zinc Finger (PLZF)+ Spermatogonia pool via Indirect Regulatory Pattern

Project description:We examined a regulatory role of the AR during the process of spermatogenesis. Using a SSCs-Sertoli cells co-culture system, we demonstrated that androgen negatively regulated Plzf in SSCs that co-exist with Sertoli cells. In addition, we identified Gata2 as a target of AR in Sertoli cells, and subsequently observed that Wilms tumor 1 (WT1) and β1-integrin as two putative intermediate molecules to transfer the differentiation signals to SSCs. This signal pathway was further verified using androgen pharmacological deprivation mice model. These results demonstrate a regulatory pattern of androgen in SSCs niche, that androgen turns off the stemness maintenance switch PLZF in undifferentiated spermatogonia populations to promote spermatogenesis in an indirect way via multiple steps of signal transduction.

Glucagon controls obesity-specific energy expenditure via persistent cAMP/PKA signaling

Project description:Glucagon (GCG) analogues are gaining attention as promising components in incretin-based therapeutics for obesity and metabolic dysfunction-associated steatohepatitis. However, the biology of chronic glucagon treatment, in particular, the molecular underpinnings of GCG-induced energy expenditure and lipid metabolism, remain poorly defined. We utilized a long-acting GCG analogue (LA-GCG) in conjunction with hepatic and adipose glucagon receptor knockout mouse models. Through an integrative approach that combined metabolic, biochemical and omics techniques, we investigated the molecular mechanisms underlying GCG-induced energy expenditure and metabolic benefits. We demonstrate that the LA-GCG enhances energy expenditure in diet-induced obese mice with an essential role of hepatic, but not adipose, GCGR signaling. Intriguingly, the enhancement in energy expenditure is observed only in obese but not in lean mice. The preferential efficacy is plausibly found in a prolonged activation of cAMP/PKA signaling through PDE4B/4D downregulation by LA-GCG. Conversely, the cAMP/PKA signaling is promptly attenuated by the PDE4B/4D activity in lean mice. Interestingly, unlike the EE phenotype, the lipid-clearing capacity of LA-GCG is independent of the PDE4/cAMP/PKA axis. These findings provide the molecular basis for GCG-induced energy expenditure and metabolic benefits and suggest the phenotypic segregation of cAMP/PKA-dependent and independent effects.
