TranscriptomicsRe-evaluation of the roles of DROSHA, Exportin 5, and DICER in microRNA biogenesis
Biogenesis of canonical microRNAs (miRNAs) involves multiple steps: nuclear processing of primary miRNA (pri-miRNA) by DROSHA, nuclear export of precursor miRNA (pre-miRNA) by Exportin 5 (XPO5), and cytoplasmic processing of pre-miRNA by DICER. To gain a deeper understanding of the contribution of e...

TranscriptomicsMicroRNA microarray in atmpk3 and atmpk6 Arabidopsis mutants
MicroRNA microarray profiling was performed in Arabidopsis seedlings - Col-0, atmpk3 and atmpk6 mutants to uncover the roles of MPK3 and MPK6 in microRNA biogenesis pathway.

TranscriptomicsIn depth analysis of the interaction of HIV 1 with cellular microRNA biogenesis and effector mechanisms
The question of how HIV 1 interfaces with cellular microRNA (miRNA) biogenesis and effector mechanisms has been highly controversial. Here, we first used deep sequencing of small RNAs present in two different infected cell lines (TZM-bl and C8166) and two types of primary human cells (CD4+ PBMCs and...

TranscriptomicsmicroRNA expression in murine hematopoietic stem cells
MicroRNAs influence hematopoietic differentiation, but little is known about their effects on the stem cell state. Here, we report that the microRNA processing enzyme Dicer is essential for stem cell persistence in vivo and a specific microRNA, miR-125a controls the size of the stem cell population ...

TranscriptomicsSRF Overexpression Leads to Altered Expression of MicroRNAs and Contributes to Cardiac Hypertrophy
The role of SRF in the regulation of microRNA expression and microRNA biogenesis in cardiac hypertrophy has not been well established. In this report, we employed a distinct transgenic mouse model to study the impact of SRF on cardiac microRNA expression and microRNA biogenesis. Cardiac-specific ove...

TranscriptomicsRegulation of the microRNA processor DGCR8 by the tumor suppressor ING1
The ING familiy of tumor suppressor proteins control several cellular functions relevant to anti-tumor protection, like cell-cycle control, apoptosis, senescence or migration. ING proteins are functionally linked to the p53 pathway, and they participate in transcriptional control via the recognisit...

TranscriptomicsNOT2 proteins promote Pol II-dependent transcription and interact with multiple miRNA biogenesis factors in Arabidopsis
MicroRNAs (miRNAs) play key regulatory roles in numerous developmental and physiological processes in animals and plants. The elaborate mechanism of miRNA biogenesis involves transcription and multiple processing steps. Here, we report the identification of a pair of evolutionarily conserved NOT2_3_...
