Natural polyamines, such as spermidine and spermine, exert strong anti-inflammatory effects, but their therapeutic benefits are limited by rapid absorption in the small intestine, resulting in low colonic availability. In this study, engineered Citrobacter freundii overexpressing ppk1 (CPP) coul...

P granules in C. elegans are required for fertility and function to maintain germ cell identity and pluripotency.  Sterility in the absence of P granules is often accompanied by the mis-expression of soma-specific proteins and the initiation of somatic differentiation in germ cells.  To investigate ...

Germ Granules Govern Small RNA Inheritance
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...

Local translation at the synapse plays key roles in neuron development and activity-dependent synaptic plasticity. mRNAs are translocated from the neuronal soma to the distant synapses as compacted ribonucleoparticles referred to as RNA granules. These contain many RNA-binding proteins, including th...

In C. elegans nematodes, components of liquid-like germ granules were shown to be required for transgenerational small RNA inheritance. Surprisingly, we show here that mutants with defective germ granules can nevertheless inherit potent small RNA-based silencing responses, but some of the mutants lo...

WAGO-4 Localization to Germ Granules Is Important for Its Accurate Small RNA Loading
The study aimed to investigate the mechanisms of Jianxin (JX) granules, a Traditional Chinese Medicine formulation, in the treatment of heart failure (HF) using metabolomic profiling. The HF model was established by ligation of left coronary artery. The successfully modeled rats were randomly divide...

These datasets profile the expression of small RNAs with 5p monophosphates and 3p hydroxyls (including miRNAs, 21U-RNAs) in young adult worms from the wt, prg-1 mutant, and fog-2 mutant backgrounds. These datasets were prepared in the Craig C. Mello laboratory using T4 RNA ligase 1. Keywords: miRNA...
