RNA-seq profiling of BAG neurons in C. elegans npr-1 and npr-1;arcp-1 animals

ABSTRACT: The extent to which behavior is shaped by experience varies between individuals. Genetic differences contribute to this variation but the neural mechanisms are not understood. In this study, we identify a natural genetic variant of the dendritic scaffolding protein ARCP-1 that modifies individual behavioral flexibility in C. elegans. Disrupting ARCP-1 alters how previous oxygen experience modulates escape behavior in response to carbon dioxide. ARCP-1 normally suppresses CO2 aversion by inhibiting signaling from the BAG CO2-sensing neurons. To further investigate how disrupting ARCP-1 alters BAG function, we specifically labeled these neurons with GFP, used FACS to isolate the fluorescent cells from acutely dissociated arcp-1 mutant and control animals, and profiled their gene expression using RNA-Seq. We find transcriptional changes for a broad range of gene classes and link altered neuropeptide expression to increased CO2 aversion in the arcp-1 mutant.

Next Generation Sequencing of PD-iPSC derived midbrain dopaminergic(mDA) neurons treated with CDC (C021 dihychloride) or BAG (BAG 956)

Project description:Purpose: The goals of this study are to identify cellular pathways to recover a-syn aggregation-mediated toxicity induced in response to CDC or BAG treatment on PD-iPSC derived mDA neurons. Methods: mRNA profiles of 30-day-old PD-mDA neurons with CDC or BAG treatment for 1 day were generated by deep sequencing, in duplicate, using Illumina HiSeq. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) followed by ANOVA (ANOVA) and TopHat followed by Cufflinks. Conclusions: Our study represents the detailed analysis of mDA neuronal transcriptomes in response to CDC or BAG treatments, with biologic replicates, generated by RNA-seq technology. Our results show that CDC or BAG treatment could rescue the toxcity from a-syn aggregation via purine metabolism / ion transport pathways.

Targeting the androgen receptor N-terminus via the cochaperone Bag-1L [ChIP-Seq]

Project description:Targeting the activation function-1 (AF-1) at the N-terminus of the androgen receptor (AR) is an attractive therapeutic alternative to the current approaches to inhibit AR action in prostate cancer (PCa). Here we show that the AR AF-1 is bound by the BAG domain of the cochaperone Bag-1L. Mutations in this domain or loss of Bag-1L abrogates AR signaling and reduces PCa growth. Correspondingly, Bag-1L protein levels increase with progression of primary prostate tumors to castration-resistant PCa, correlating inversely with patient response to abiraterone therapy. Intriguingly, BAG domain residues important for its interaction with the AR AF-1 overlap a potentially druggable pocket of this protein. Bag-1L is therefore a putative therapeutic target for the inhibition of AR AF-1 activity.

Over-expression of BAG-1 in head and neck squamous cell carcinomas (HNSCC) is associated with cisplatin-resistance

Project description:In order to improve therapy for head and neck squamous cell carcinoma (HNSCC), biomarkers associated with local and/or distant tumor relapses and cancer drug resistance are urgently needed. This study identified a potential biomarker, BAG-1 (Bcl-2 associated athanogene-1), that is implicated in HNSCC insensitive to cisplatin and tumor progression. Advanced HNSCC cells revealed resistant to cisplatin accompanied by increased expression of BAG-1 protein. siRNA knockdown of BAG-1 expression resulted in significant improvement of HNSCC sensitivity to cisplatin. BAG-1 expression enhanced stability of BCL-xL and conferred cisplatin resistant to the HNSCC cells. In addition, high levels of expression of phospho AKT, BAG-1, and BCL- xL were observed in advanced HNSCC compared to in that of primary HNSCC. Conclusion: Increased expression of BAG-1 was associated with cisplatin resistance and tumor progression in HNSCC patients and warrants further validation in larger independent studies. Over expression of BAG-1 may be a biomarker for cisplatin resistance in patients with primary or recurrent HNSCCs and targeting BAG-1 could be helpful in overcoming cisplatin resistance.

Acquisition of Innate Odor Preference Depends on Spontaneous and Experiential Activities During Critical Period

Project description:Animals possess inborn ability to recognize certain odors to avoid predators, seek food and find mates. Innate odor preference has been thought to be genetically hardwired. Here we report that acquisition of innate odor recognition requires spontaneous neural activity and is influenced by sensory experience during early postnatal development. Genetic silencing of mouse olfactory sensory neurons during the critical period has little impact on odor sensitivity, discrimination and recognition later in life. However, it abolishes innate odor preference and alters the patterns of activation in brain centers. Moreover, exposure to an aversive odor during the critical period abolishes aversion in adulthood in an odor specific manner. The loss of innate aversion is associated with broadened projection of OSNs. Thus, a delicate balance of neural activity is required during critical period in establishing innate odor preference and ectopic projection is a convergent mechanism to alter innate odor valence

LNCaP prostate cancer cell lines overexpressing wild-type or GARRPR-mutant Bag-1L

Project description:The BF-3 pocket of the androgen receptor (AR) has been identified as an allosteric modulator of the transactivation function of the AR. We now demonstrate that a duplicated GARRPR motif at the N-terminus of the cochaperone Bag-1L functions through this BF-3 domain. Amino acid exchanges in these two motifs impair binding of Bag-1L to the AR but increase the androgen-dependent activation of a subset of AR-target genes. We have therefore identified GARRPR as a novel BF-3 regulatory sequence important for fine-tuning the activity of the receptor. LNCaP cells stably expressing the empty vector construct (=control), or wild-type or N-terminal GARRPR mutant Bag-1L were cultured under hormone-starvation conditions for 72 h and then treated with vehicle or 10 nM DHT for 4 h. Biological triplicate samples were analyzed for each cell line.
