Cell Biology, Genetics, and Biochemistry for Pre-Clinical Students

, 2022
This book is an undergraduate medical-level resource for foundational knowledge across the disciplines of genetics, cell biology and biochemistry. This text is designed for a course in first year undergraduate medical course that is delivered typically before students start to explore systems physiology and pathophysiology. The text is meant to provide

In vivo evidence for glycyl radical insertion into a catalytically inactive variant of pyruvate formate‐lyase

FEBS Letters, EarlyView.
Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Inhibitors of sterol synthesis. Submicromolar 14 alpha-ethyl-5 alpha-cholest-7-ene-3 beta, 15 alpha-diol causes a major modification of the sterol composition of CHO-K1 cells and a marked change in cell morphology.

Journal of Lipid Research, 1994
Incubation of Chinese hamster ovary cells (CHO-K1) with 14 alpha-ethyl-5 alpha-cholest-7-ene-3 beta,15 alpha-diol (0.1 microM) in lipid-deficient medium led to a major change in cellular sterol composition, which was characterized by a very marked ...

Cloning BRD4 long isoform into overexpression vectors for stable overexpression of BRD4-L in mammalian cells

STAR Protocols, 2022
Summary: Molecular cloning of BRD4-L is a challenging technique, because the DNA insert is formed by a long, GC-rich sequence, which folds into secondary structures.

P‐glycoprotein modulates the fluidity gradient of the plasma membrane of multidrug resistant CHO cells

FEBS Letters, EarlyView.
To explore the impact of the overexpression of the multidrug‐transporter P‐glycoprotein (ABCB1) on membrane fluidity, we compared the transversal gradient of mobility and microviscosity in plasma membranes of drug‐sensitive Chinese hamster ovary cells (AuxB1) and their multidrug‐resistant derivatives (B30) using the fluorescent n‐(9‐anthroyloxy) fatty ...

G-quadruplex Structures Contribute to Differential Radiosensitivity of the Human Genome

iScience, 2019
Summary: DNA, the fundamental unit of human cell, generally exists in Watson-Crick base-paired B-DNA form. Often, DNA folds into non-B forms, such as four-stranded G-quadruplexes.

Differential neuronal functions of LNX1 and LNX2 revealed by behavioural analysis in single and double knockout mice

Behavioral and Brain Functions
Background Ligand of NUMB protein-X 1 (LNX1) and LNX2 proteins are closely related PDZ domain-containing E3 ubiquitin ligases that interact with and potentially modulate numerous synaptic and neurodevelopmentally important proteins.

Evolutionary interplay between viruses and R‐loops

FEBS Letters, EarlyView.
Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

The microvascular endothelium of the blood-brain barrier is highly restrictive to JC Polyomavirus neuroinvasion

Microbiology Spectrum
JC Polyomavirus is the causative agent of progressive multifocal leukoencephalopathy (PML), an often-fatal demyelinating disease. Unfortunately, a diagnosis of PML occurs only after patients have suffered irreversible neuropathologies.

Flow‐based immunomagnetic enrichment of circulating tumor cells from diagnostic leukapheresis product

Molecular Oncology, EarlyView.
The number of circulating tumor cells obtained from prostate cancer patients was increased approximately 5‐fold compared to regular CellSearch when processing 2 mL diagnostic leukapheresis material aliquots and increased by 44‐fold when processing 20 mL DLA aliquots using the flow enrichment target capture Halbach‐array.
