Autism-associated SNPs in the clock genes _npas2_, _per1_ and the homeobox gene _en2_ alter DNA sequences that show characteristics of microRNA genes. [PDF]

open access: yes, 2008
Intronic single nucleotide polymorphisms (SNPs) in the clock genes _npas2_ and _per1_ and the homeobox gene _en2_ are reported to be associated with autism.

MicroRNA Factory: RISC Assembly from Precursor MicroRNAs [PDF]

open access: yesMolecular Cell, 2012
RNA silencing requires assembly of an effector complex, RNA-induced silencing complex (RISC), composed of a small RNA and the Ago protein. In this issue of Molecular Cell, Liu et al. (2012) provide insights of miRNP/RISC assembly pathways in mammals, using an in vitro human RISC assembly assay programmed by pre-miRNAs.

Next‐generation proteomics improves lung cancer risk prediction

open access: yesMolecular Oncology, EarlyView.
This is one of very few studies that used prediagnostic blood samples from participants of two large population‐based cohorts. We identified, evaluated, and validated an innovative protein marker model that outperformed an established risk prediction model and criteria employed by low‐dose computed tomography in lung cancer screening trials.

Fasting induces a subcutaneous-to-visceral fat switch mediated by microRNA-149-3p and suppression of PRDM16

open access: yesNature Communications, 2016
Visceral adiposity is associated with metabolic diseases, whereas subcutaneous adiposity is comparatively benign. Here, the authors report that subcutaneous adipose tissue adopts visceral-like characteristics in response to prolonged fasting, and show ...

Salmonella produce microRNA-like RNA fragment Sal-1 in the infected cells to facilitate intracellular survival. [PDF]

open access: yes, 2017
Salmonella have developed a sophisticated machinery to evade immune clearance and promote survival in the infected cells. Previous studies were mostly focused on either bacteria itself or host cells, the interaction mechanism of host-pathogen awaits ...

MicroRNA-17, MicroRNA-19b, MicroRNA-146a, MicroRNA-302d Expressions in Hepatoblastoma and Clinical Importance

open access: yesJournal of Pediatric Hematology/Oncology, 2019
Hepatoblastoma (HB) is the most common liver malignancy in children. The prognosis changes according to the histologic subtypes of HB. In the present study, we aimed to characterize the expression level of selected microRNAs (miRNAs) in HB as well as in histologic subtypes, and to consider the association with the prognosis.

Understanding cooperativity of microRNAs via microRNA association networks [PDF]

open access: yesBMC Genomics, 2013
MicroRNAs (miRNAs) are key components in post-transcriptional gene regulation in multicellular organisms. As they control cooperatively a large number of their target genes, they affect the complexity of gene regulation. One of the challenges to understand miRNA-mediated regulation is to identify co-regulating miRNAs that simultaneously regulate their ...

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

open access: yesMolecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

MicroR159 regulation of most conserved targets in Arabidopsis has negligible phenotypic effects [PDF]

open access: yes, 2016
BACKGROUND A current challenge of microRNA (miRNA) research is the identification of biologically relevant miRNA:target gene relationships. In plants, high miRNA:target gene complementarity has enabled accurate target predictions, and slicing of target ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...
