Multidimensional OMICs reveal ARID1A orchestrated control of DNA damage, splicing, and cell cycle in normal‐like and malignant urothelial cells

Molecular Oncology, EarlyView.
Loss of the frequently mutated chromatin remodeler ARID1A, a subunit of the SWI/SNF cBAF complex, results in less open chromatin, alternative splicing, and the failure to stop cells from progressing through the cell cycle after DNA damage in bladder (cancer) cells. Created in BioRender. Epigenetic regulators, such as the SWI/SNF complex, with important

CHARACTERIZATION OF 18S RIBOSOMAL RNA FRAGMENT FROM Solanum tuberosum L. var. Granola POTATO

Scripta Biologica, 2018
Potato (Solanum tuberosum L.) is a prime horticultural commodity. One of the varieties of potato that widely cultivated in Indonesia is Granola. This study characterized the variety Granola based on the 18S sequences of rRNA gene fragment.

Variation of expression levels of seven housekeeping genes at different life-history stages in Porphyra yezoensis. [PDF]

PLoS ONE, 2013
In order to identify the optimal internal control for relative real-time PCR when studying target gene expression in the red alga Porphyra yezoensis, we quantified the expression of seven housekeeping genes (18S ribosomal RNA, 30S ribosomal protein S8 ...

Stochasticity and traffic jams in the transcription of ribosomal RNA: Intriguing role of termination and antitermination [PDF]

Proc. Natl. Acad. Sci. USA 105, 18159-18164 (2008), 2008
In fast growing bacteria, ribosomal RNA (rRNA) is required to be transcribed at very high rates to sustain the high cellular demand on ribosome synthesis. This results in dense traffic of RNA polymerases (RNAP). We developed a stochastic model, integrating results of single-molecule and quantitative in vivo studies of E.

Targeting the AKT/mTOR pathway attenuates the metastatic potential of colorectal carcinoma circulating tumor cells in a murine xenotransplantation model

Molecular Oncology, EarlyView.
Dual targeting of AKT and mTOR using MK2206 and RAD001 reduces tumor burden in an intracardiac colon cancer circulating tumor cell xenotransplantation model. Analysis of AKT isoform‐specific knockdowns in CTC‐MCC‐41 reveals differentially regulated proteins and phospho‐proteins by liquid chromatography coupled mass spectrometry. Circulating tumor cells

Nucleotide sequence of the 5′-and 3′-domains for rabbit 18S ribosomal RNA [PDF]

Nucleic Acids Research, 1982
By direct RNA sequence analysis we have determined the primary structures of both the 5' and 3' domains for rabbit 18S ribosomal RNA. Purified 18S rRNA was labeled in vitro at either its 5' or 3' terminus with 32P, base-specifically fragmented enzymatically and chemically, and the resulting fragments electrophoretically fractionated by size in adjacent

Stochastic kinetics of ribosomes: single motor properties and collective behavior [PDF]

Physical Review E, vol.80, 011908 (2009), 2009
Synthesis of protein molecules in a cell are carried out by ribosomes. A ribosome can be regarded as a molecular motor which utilizes the input chemical energy to move on a messenger RNA (mRNA) track that also serves as a template for the polymerization of the corresponding protein.

Tryptophan‐sensing receptor GPR142 expression levels are directly regulated by proinflammatory cytokines in ghrelin‐producing cells

FEBS Open Bio, EarlyView.
GPR142, a tryptophan‐sensing receptor, stimulates gastrointestinal hormones like ghrelin and is linked to inflammation regulation. Proinflammatory cytokines suppress ghrelin production, while tryptophan levels decrease via IDO1 activation. Our findings reveal that proinflammatory cytokines directly regulate GPR142 expression in ghrelin‐producing cells,

Comprehensive analysis of the circular RNA expression profile and circRNA–miRNA–mRNA network in the goat skin with divergent wool curvature

Animal Research and One Health, EarlyView., 2023
In our study, we conducted circRNA expression profiling of Zhongwei goat skin exhibiting divergent curvature wool phenotypes at two developmental stages using the RNA‐seq. Functional verification assay demonstrated that circRNA8782 regulated fibroblast proliferation.
