Small RNAseq for B16F1 cells exposed to BrdU or L-Tyr

Project description:Purpose: to evaluate changes in the expression of microRNAs, which contribute to explain a phenotype of differential pigmentation and reduction of proliferation, in B16F1 melanoma cells exposed to analogue of tymidine BrdU or aminoacid L-Tyr Methods: Small RNAseq evaluation of the expression profiles of miRNAs in B16F1 melanoma cells exposed to BrdU (0.25 μg / mL) and L-Tyr (5 mM) for 72 h, as well as the expression by RT-qPCR of some molecular targets related with melanogenesis, cell cycle and senescence and construction of network models of regulation and co-expression of microRNAs. Results: It was confirmed that stimulation or melanogenic repression with L-Tyr or BrdU, respectively, generates changes in melanin concentration, reduction in proliferation and changes in expression of microRNAs 470-3p, 470-5p, 30d-5p , 129-5p, 148b-3p, 27b-3p and 211-5p, which presented patterns of coordinated co-expression, related to melanogenesis through their putative targets MITF, Tyr and Tyrp1 and control of cell cycle and senescence: Cyclin D1, Cdk2, Cdk4 and p21. Conclusion: This work improves our understanding of the events of melanogenesis, cell cycle control, and senescence mediated by the coordinated expression of miRNAs and helps to develop new approaches to a molecular biology of melanoma that operates in network

Comparison of transcriptomic profile of the murine B16F1-GFP-M melanoma cells with the derived dormant B16F1-GFP-D, B16F1-GFP-DB#1, B16F1-GFP-DB#2, B16F1-GFP-DB#3 melanoma cells

Project description:Cancer patients after successful therapy contain nested in their organs and/or circulating in the systemic fluids tumor cells that remain asymptomatic for an extended period of time. They stay dormant with no apparent immediate potential to develop into a clinically manifested tumor until activated by yet not well defined mechanisms. We previously developed tumor dormancy model of murine melanoma, a cancer with a high potential of phenotype plasticity to adapt to micro-environmental changes, in which to investigate cellular quiescence and related factors as a potential mechanism of tumour dormancy. In this study, to explore molecular mechanism responsible for cellular dormancy, we performed a comparative transcriptome analysis of dormant B16F1-GFP-D and derived dormant brain metastasis (DB) with maternal B16F1-GFP-M cells.

Transcription profiling of mouse untreated melanoma B16F1 cells vs control

Project description:B16F1 cells are a good model to study cell motility and cytoskeletal organization. In our lab, a combination of microscopy and gene silencing was used to approach the problem. Having gene expression profiles for B16F1 would facilitate and support subsequent gene silencing by RNAi as well as potentially identify new molecular players. We used microarrays to detail the expression profiles in cells cultured in regular conditions. These profile will serve as a reference point for further studies. Experiment Overall Design: Three biological replicats of control untreated B16F1 mouse melanoma cells were processed on mouse GeneChip arrays 430A. Reliability, variability, and reprodusibility of data generated by microarrays were addressed.

Nystagmus in the B6(CG)Tyr(c-2J)/J Albino Mouse: A Functional and RNAseq Analysis

Project description:PURPOSE: Infantile nystagmus syndrome (INS) is a gaze-holding disorder characterized by conjugate, uncontrolled eye oscillations that can result in significant visual acuity loss. INS is often associated with albinism, but the mechanism is unclear. Albino mice have nystagmus; however, a pigmented mouse with a tyr mutation making it phenotypically albino, the B6(CG)-Tyr(c-2J)/J (B6 albino), had not been tested. We tested optokinetic nystagmus reflexes (OKN) in B6 albino and control mice. RNA-Seq was performed on extraocular muscles (EOM), tibialis anterior muscle (TA), abducens (CN6), and oculomotor (CN3) neurons to uncover molecular differences that could account for nystagmus.

The effect of BrdU on gene expression profiles of B6C3F1 mice treated with furan

Project description:Furan is a mouse and rat hepatocarcinogen. We sought to determine the dose-dependent changes in gene expression upon exposure of B6C3F1 mice to furan in order to better understand furan’s mode of action. In this study we examined the transcriptional response in liver tissue of female B6C3F1 mice to BrdU treatment (in drinking water for 5 days before sacrifice). This was a toxicogenomic study in which mice were also exposed to 0, 1 or 8 mg/kg bw furan (by oral gavage) for 3 weeks. Mice were sacrificed four hours after the final furan exposure. Each dose group had 4-5 biological replicates. We used a two-colour reference design and SurePrint G3 Mouse GE 8x60K microarrays (Agilent). Please note that data for all non-BrdU treated animals was previously reported in GEO [GSE48644]. All samples (with or without BrdU) were part of the same randomized block design for the microarrays.
