Study on rRNA Genes in Mycobacterium smegmatis [PDF]

Microbiology and Immunology, 1988
AbstractThe number of rRNA genes in Mycobacterium smegmatis was examined by hybridization of BamHI and SalI digests of chromosomal DNA with 3′‐end‐labeled 5S, 16S, 23S rRNA and tRNA. Each RNA probe gave two hybridization bands. The PstI fragments of 6.6 kilobases were cloned to pBR322.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Isolation of Partial Housekeeping Genes on Tuntun Angin (Elaeocarpus floribundu)

Biosaintifika: Journal of Biology & Biology Education, 2019
Some genes like 18S rRNA, 26S rRNA, elongation factor 1-alpha (EF1a), and beta-tubulin (TUB) are members of housekeeping genes group that are commonly used as internal control in gene expression study.

A renaissance for the pioneering 16S rRNA gene [PDF]

Current Opinion in Microbiology, 2008
Culture-independent molecular surveys using the 16S rRNA gene have become a mainstay for characterizing microbial community structure over the past quarter century. More recently this approach has been overshadowed by metagenomics, which provides a global overview of a community's functional potential rather than just an inventory of its inhabitants ...

Glycogen Synthase Kinase (GSK) 3β phosphorylates and protects nuclear myosin 1c from proteasome-mediated degradation to activate rDNA transcription in early G1 cells [PDF]

, 2014
Nuclear myosin 1c (NM1) mediates RNA polymerase I (pol I) transcription activation and cell cycle progression by facilitating PCAF-mediated H3K9 acetylation, but the molecular mechanism by which NM1 is regulated remains unclear.

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance

Aging and Cancer, EarlyView.
NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

Piezoelectric Surface Charge and Dynamic Stimulation Synergize to Promote Cardiac Myoblast Alignment and Maturation

Advanced Healthcare Materials, EarlyView.
Surface polarization of PVDF films combined with mechanical stimulation generates piezoelectric electrical cues that modulate cardiomyoblast behaviour. Non‐poled and poled PVDF substrates provide distinct electroactive microenvironments influencing cell adhesion, proliferation, and differentiation.

Rearranged Subtelomeric rRNA Genes in Giardia duodenalis [PDF]

Eukaryotic Cell, 2005
ABSTRACT Giardia duodenalis has linear chromosomes capped with typical eukaryotic repeats [(TAGGG) n ], subtelomeric rRNA genes, and telomere gene units. The absence of two closely associated NotI sites in the large-subunit rRNA gene was used as an indicator in ...
