Dihydrofolate reductase of Streptococcus faecium II. Purification and some properties of two dihydrofolate reductases from the Amethopterin-resistant mutant, Streptococcus Faecium Var. Durans Strain A [PDF]

, 1968
From a single amethopterin-resistant organism, Streptococcus faecium var. durans strain A, two different dihydrofolate reductases have been obtained as essentially homogeneous proteins in good yield.

Modeling Dihydrofolate Reductase

The FASEB Journal, 2010
Dihydrofolate reductase (DHFR) is a ubiquitous enzyme that catalyzes the reduction of dihydrofolate (DHF) to tetrahydrofolate (THF). THF is crucial for purine and thymidylate synthesis, precursors to DNA and RNA. Inhibition of DHFR leads to cessation of cell proliferation because the cell

Synthetic biology approaches to generate temperature‐sensitive alleles for the Sterile Insect Technique

Insect Science, EarlyView.
Abstract The Sterile Insect Technique (SIT) is an environmentally friendly, sustainable pest control approach, which uses large‐scale releases of sterile insects to suppress or eradicate target populations through infertile matings. The efficiency of SIT is enhanced by male‐only releases requiring genetic sexing strains (GSSs) that are classically ...

Metformin sensitises hepatocarcinoma cells to methotrexate by targeting dihydrofolate reductase

Cell Death and Disease, 2021
Metformin, the first-line drug for type II diabetes, has recently been considered an anticancer agent. However, the molecular target and underlying mechanism of metformin’s anti-cancer effects remain largely unclear.

Mitochondrial Protein Import [PDF]

, 1987
The role of nucleoside triphosphates (NTPs) in mitochondrial protein import was investigated with the precursors of N. crassa ADP/ATP carrier, F1-ATPase subunit β, F0-ATPase subunit 9, and fusion proteins between subunit 9 and mouse dihydrofolate ...

Anti‐inflammatory effects of physical stimuli: The central role of networks in shaping the future of pharmacological research

British Journal of Pharmacology, EarlyView.
Addressing complexity in the study of life sciences through Systems Biology and Systems Medicine has been transformative, making Systems Pharmacology the next logical step. In this review, we focus on physical stimuli, whose potential in pharmacology has been neglected, despite demonstrated therapeutic properties.

Hippo Pathway Drives Durable Non‐Cell‐Autonomous Ferroptosis Resistance in Lung Cancer

Cancer Science, EarlyView.
YAP/TAZ, key effectors in lung cancer progression, paradoxically sensitize tumor cells to ferroptosis. This study reveals that YAP/TAZ‐low cells confer non‐cell‐autonomous, GCH1‐mediated durable ferroptosis resistance to neighboring YAP/TAZ‐high cells via a soluble factor, highlighting a Hippo pathway‐linked mechanism of tumor adaptation and survival ...
