Isolation and Identification of an α-Galactosidase-Producing Lactosphaera pasteurii Strain and Its Enzymatic Expression Analysis

Molecules, 2022
α-Galactosidase (EC 3.2.1.22) refers to a group of enzymes that hydrolyze oligosaccharides containing α-galactoside-banded glycosides, such as stachyose, raffinose, and verbascose.

pHYPER, a shRNA vector for high-efficiency RNA interference in embryonic stem cells

BioTechniques, 2007
RNA interference (RNAi) is a powerful method to generate loss-of-function phenotypes. Plasmid vectors with RNA polymerase III promoters have been developed to express short hairpin RNAs (shRNAs) in mammalian cells.

Epigenetic regulation of cholesterol homeostasis [PDF]

Frontiers in Genetics, 2014
Although best known as a risk factor for cardiovascular disease, cholesterol is a vital component of all mammalian cells. In addition to key structural roles, cholesterol is a vital biochemical precursor for numerous biologically important compounds including oxysterols and bile acids, as well as acting as an activator of critical morphogenic systems ...

Engineering a CRISPR-associated IscB system for developing miniature genome-editing tools in human cells and mouse embryos

Nature Communications
IscB, as the putative ancestor of Cas9, possesses a compact size, making it suitable for in vivo delivery. OgeuIscB is the first IscB protein known to function in eukaryotic cells but requires a complex TAM (NWRRNA).

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

scIVNL-seq resolves in vivo single-cell RNA dynamics of immune cells during Salmonella infection

Nature Communications
The immune response against pathogens involves multiple cell state transitions and complex gene expression changes. Here, we establish a single-cell in vivo new RNA labeling sequencing method (scIVNL-seq) and apply it to survey time-resolved RNA dynamics

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Asymmetric division of stem cells and its cancer relevance

Cell Regeneration
Asymmetric division is a fundamental process for generating cell diversity and maintaining the stem cell population. During asymmetric division, proteins, organelles, and even RNA are distributed unequally between the two daughter cells, determining ...

PICALM::MLLT10 translocated leukemia

FEBS Letters, EarlyView.
This comprehensive review of PICALM::MLLT10 translocated acute leukemia provides an in‐depth review of the structure and function of CALM, AF10, and the fusion oncoprotein (1). The multifaceted molecular mechanisms of oncogenesis, including nucleocytoplasmic shuttling (2), epigenetic modifications (3), and disruption of endocytosis (4), are then ...
