miR-375 is not expression in human macrophages, however there is an enhanced accumulation of miR-375 in macrophages upon coculture with breast cancer cells. The target landscape of this miR in macrophages is not known. Ago-RIP-Seq was aimed to identify miR-375 targets in human macrophages.

We performed Ago HITS-CLIP to identify targets of viral and human miRNAs in latently KSHV-infected PEL cells Ago HITS-CLIP was performed in two latently infected PEL cell lines, BCBL-1 and BC-3; Argonaute-immunoprecipitation of UV cross-linked Ago-miRNA-mRNA complexes, followed by RNA isolation, lib...

Purpose: The establishment of cell lineages occurs via a dynamic progression of gene regulatory networks that underlie developmental commitment and differentiation. To investigate how microRNAs (miRs) function in this process, we compared miRs and miR targets at the initiation of the two major ectod...

In humans, there are four Ago proteins (Ago1M-bM-^@M-^S4) and AGO1- and 2 were previously implicated in TGS induced by exogenous siRNAs and microRNAs (miRs) directed against gene promoter transcripts via promotion of changes in histone covalent modifications and DNA methylation. Not-with-standing, m...

AGO protein immunoprecipitation was combined with high-throughput sequencing of associated small RNAs. AGO2, AGO10, and to a lesser extent AGO1 were shown to associate with siRNAs derived from silencing suppressor (HC-Pro)-deficient TuMV-AS9, but not with siRNAs derived from wild-type TuMV. Co-immun...

During microRNA (miRNA)-guided gene silencing, Argonaute (Ago) proteins interact with a member of the TNRC6/GW protein family. Here we used a short GW protein-derived peptide fused to GST and demonstrate that it binds to Ago proteins with high affinity. This allows for the simultaneous isolation of ...

Small non-coding RNAs have emerged as key players in modulation of viral infection. A unique example is the critical dependence of hepatitis C virus (HCV) on the liver-specific microRNA (miRNA), miR-122, which has surfaced as therapeutic target. Here, we used crosslinking immunoprecipitation (CLIP) ...

To fully characterize smRNAs associated with AGO1 and AGO4, we developed a two-step protocol to purify AGO/smRNA complexes from flowers, leaves, roots and seedlings with enhanced purity, and sequenced the smRNAs by IlluminaM-CM-"M-BM-^@M-BM-^Ys technology. We identified some additional miRNAs, colla...

High-throughput pyrosequencing of endogenous small RNAs from >95% male enriched populations of alg-3(tm1155);alg-4(ok1041);fog-2(q71) and fog-2(q71) worms as well as purified spermatids from fem-3(q20) adult worms. Gametogenesis is thermosensitive in numerous metazoa ranging from worms to man. In C...

MicroRNA precursors (pre-miRNAs) are short hairpin RNAs that are rapidly processed into mature microRNAs (miRNAs) in the cytoplasm. Due to their low abundance in cells, sequencing-based studies of pre-miRNAs have been limited. We successfully enriched for and deep sequenced pre-miRNAs in human cells...
