Genomic and epigenomic mapping of leptin-responsive neuronal populations involved in body weight regulation. [PDF]

, 2019
Genome wide association studies (GWAS) in obesity have identified a large number of noncoding loci located near genes expressed in the central nervous system.

Circular RNA expression landscapes in myelodysplastic neoplasms: Associations with mutational signatures and disease progression

Molecular Oncology, EarlyView.
In this explorative study, the abundance of circular RNA molecules in bone marrow stem cells was found to be elevated in patients with high‐risk myelodysplastic neoplasms, and to be associated with an increased risk of progression to acute myeloid leukemia.

Conservation and implications of eukaryote transcriptional regulatory regions across multiple species

BMC Genomics, 2008
Background Increasing evidence shows that whole genomes of eukaryotes are almost entirely transcribed into both protein coding genes and an enormous number of non-protein-coding RNAs (ncRNAs).

Transcription regulatory elements In the late region of bacteriophage T5 DNA

Nucleic Acids Research, 1983
Transcription promoters and terminators have been cloned from the late region of bacteriophage T5 DNA and their strengths determined in vivo in plasmid derivatives. DNA sequence analysis shows these transcription signals to be remarkable in that, in all four cases studied in detail, the promoters and terminators overlapped or were very close together.

Colorectal cancer‐derived FGF19 is a metabolically active serum biomarker that exerts enteroendocrine effects on mouse liver

Molecular Oncology, EarlyView.
Meta‐transcriptome analysis identified FGF19 as a peptide enteroendocrine hormone associated with colorectal cancer prognosis. In vivo xenograft models showed release of FGF19 into the blood at levels that correlated with tumor volumes. Tumoral‐FGF19 altered murine liver metabolism through FGFR4, thereby reducing bile acid synthesis and increasing ...

Subtype‐specific enhancer RNAs define transcriptional regulators and prognosis in breast cancers

Molecular Oncology, EarlyView.
This study employed machine learning methodologies to perform the subtype‐specific classification of RNA‐seq data sets, which are mapped on enhancers from TCGA‐derived breast cancer patients. Their integration with gene expression (referred to as ProxCReAM eRNAs) and chromatin accessibility profiles has the potential to identify lineage‐specific and ...

Functional Analysis of Heme Regulatory Elements of the Transcriptional Activator Hap1

Biochemical and Biophysical Research Communications, 2000
Heme regulation of the activity of diverse proteins was thought to be mediated by heme-responsive motifs (HRMs). The yeast transcriptional activator Hap1 contains seven HRMs: HRM1-7. Three copies of a 17-amino-acid repeat are also located in the region encompassing HRM1 to -6. We examined the effects of these HRMs and repeats on heme regulation of Hap1

Genetic attenuation of ALDH1A1 increases metastatic potential and aggressiveness in colorectal cancer

Molecular Oncology, EarlyView.
Aldehyde dehydrogenase 1A1 (ALDH1A1) is a cancer stem cell marker in several malignancies. We established a novel epithelial cell line from rectal adenocarcinoma with unique overexpression of this enzyme. Genetic attenuation of ALDH1A1 led to increased invasive capacity and metastatic potential, the inhibition of proliferation activity, and ultimately ...
