Small Non-coding RNAs Are Dysregulated in Huntington’s Disease Transgenic Mice Independently of the Therapeutic Effects of an Environmental Intervention

Small Non-coding RNAs Are Dysregulated in Huntington's Disease Transgenic Mice Independently of the Therapeutic Effects of an Environmental Intervention

Huntington’s illness (HD) is a neurodegenerative dysfunction brought on by a trinucleotide repeat enlargement in the huntingtin gene. Transcriptomic dysregulations are well-documented in HD and alterations in small non-coding RNAs (sncRNAs), notably microRNAs (miRNAs), may underpin that phenomenon. Additionally, environmental enrichment (EE), which is used to mannequin a stimulating way of life in pre-clinical analysis, … Read more

Of rodents and ruminants: a comparison of small noncoding RNA requirements in mouse and bovine reproduction

Ruminants are main producers of meat and milk, thus managing their reproductive potential is a key ingredient in cost-effective, protected, and environment friendly meals manufacturing. Of explicit concern, defects in male germ cells and feminine germ cells might result in considerably lowered reside births relative to fertilization. However, the underlying molecular drivers of these defects … Read more

A Novel Small RNA Promotes Motility and Virulence of Enterohemorrhagic Escherichia coli O157:H7 in Response to Ammonium

A Novel Small RNA Promotes Motility and Virulence of Enterohemorrhagic Escherichia coli O157:H7 in Response to Ammonium

Enterohemorrhagic Escherichia coli serotype O157:H7 (O157) is a crucial, foodborne, human intestinal pathogen that causes extreme acute hemorrhagic diarrhea, belly cramping, and even loss of life. Small RNAs (sRNAs) are noncoding regulatory molecules that sense environmental adjustments and set off numerous virulence-related signaling pathways; nonetheless, few such sRNAs have been recognized in O157. Here, we report a … Read more

The immune and metabolic changes with age in giant panda blood by combined transcriptome and DNA methylation analysis

Giant panda (Ailuropoda melanoleuca) is an endangered mammalian species. Exploring immune and metabolic changes that happen in giant pandas with age is vital for his or her safety. In this examine, we systematically investigated the physiological and biochemical indicators in blood, in addition to the transcriptome, and methylation profiles of younger, grownup, and outdated giant … Read more

Rare genetic variation at transcription factor binding sites modulates local DNA methylation profiles

Rare genetic variation at transcription factor binding sites modulates local DNA methylation profiles

Although DNA methylation is one of the best characterised epigenetic mark, the mechanism by which it’s focused to particular areas within the genome stays unclear. Recent research have revealed that local DNA methylation profiles may be dictated by cis-regulatory DNA sequences that primarily function by way of DNA-binding components. Consistent with this discovering, we now … Read more

DNA methylation changes in response to ocean acidification at the time of larval metamorphosis in the edible oyster, Crassostrea hongkongensis

Introduction: Recently we have identified a novel RASSF1C-PIWIL1-piRNA pathway that promotes lung cancer cell progression and migration. PIWI-like proteins interact with piRNAs to form complexes that regulate gene expression at the transcriptional and translational levels. We have illustrated in previous work that RASSF1C modulates the expression of the PIWIL1-piRNA gene axis, suggesting the hypothesis that the RASSF1C-PIWI-piRNA pathway could potentially contribute to lung cancer stem cell development and progression, in part, through modulation of gene methylation of both oncogenic and tumor suppressor genes. Therefore, we tested this hypothesis using a non-small cell lung cancer (NSCLC) cell model to identify Candidate Differentially Methylated Regions (DMRs) modulated by the RASSF1C-PIWIL1-piRNA pathway. Materials and methods: We studied the impact of over-expressing RASSF1C and knocking down RASSF1C and PIWIL1 expression on global gene DNA methylation in the NSCLC cell line H1299 using the Reduced Representation Bisulfite Sequencing (RRBS) method. Results: DMRs were identified by comparing DNA methylation profiles of experimental and control cells. Over-expression of RASSF1C and knocking down RASSF1C and PIWIL1 modulated DNA methylation of genomic regions; and statistically significant candidate genes residing DMR regions in lung cancer cells were identified, including oncogenes and tumor suppressors. One of the hypermethylated genes, Gem Interacting Protein (GMIP), displays tumor suppressor properties. GMIP expression attenuates lung cancer cell migration, and its over-expression is associated with longer survival of lung cancer patients. Conclusions: The RASSF1C-PIWI-piRNA pathway modulates key oncogenes and tumor suppressor genes. GMIP is hypermethylated by this pathway and has tumor suppressor properties.

Unprecedented price of elevated CO2 degree in the ocean and the subsequent modifications in carbonate system including decreased pH, often called ocean acidification (OA), is predicted to disrupt not solely the calcification course of but additionally a number of different physiological and developmental processes in a selection of marine organisms, including edible oysters.
