Nucleosided derived antibiotics to fight microbial drug resistance: New utilities for an established class of drugs? [PDF]

open access: yes, 2016
Novel antibiotics are urgently needed to combat the rise of infections due to drug-resistant microorganisms. Numerous natural nucleosides and their synthetically modified analogues have been reported to have moderate to good antibiotic activity against ...

Oleanolic acid blocks the purine salvage pathway for cancer therapy by inactivating SOD1 and stimulating lysosomal proteolysis

open access: yesMolecular Therapy: Oncolytics, 2021
Metabolic reprogramming is a core hallmark of cancer and is key for tumorigenesis and tumor progression. Investigation of metabolic perturbation by anti-cancer compounds would allow a thorough understanding of the underlying mechanisms of these agents ...

Nucleotide precursors prevent folic acid-resistant neural tube defects in the mouse [PDF]

open access: yes, 2013
Closure of the neural tube during embryogenesis is a crucial step in development of the central nervous system. Failure of this process results in neural tube defects, including spina bifida and anencephaly, which are among the most common birth defects ...

Cathepsin B modulates lysosomal biogenesis and host defense against Francisella novicida infection [PDF]

open access: yes, 2016
Lysosomal cathepsins regulate an exquisite range of biological functions, and their deregulation is associated with inflammatory, metabolic, and degenerative diseases in humans.

Intrauterine Undernourishment Alters TH1/TH2 Cytokine Balance and Attenuates Lung Allergic Inflammation in Wistar Rats [PDF]

open access: yes, 2012
IL-4 produced by Th2 cells can block cytokine production by Th1 cells, and Th1 IFN-gamma is known to counterregulate Th2 immune response, inhibiting allergic eosinophilia.

Falling from grace: HPRT is not suitable as an endogenous control for cancer-related studies

open access: yesMolecular & Cellular Oncology, 2019
HPRT is a housekeeping enzyme involved in recycling guanine and inosine in the purine salvage pathway. As a housekeeping gene, HPRT has been widely used as an endogenous control for molecular studies evaluating changes in gene expression.

The Secreted Acid Phosphatase Domain-Containing GRA44 from Toxoplasma gondii Is Required for c-Myc Induction in Infected Cells. [PDF]

open access: yes, 2020
During host cell invasion, the eukaryotic pathogen Toxoplasma gondii forms a parasitophorous vacuole to safely reside within the cell, while it is partitioned from host cell defense mechanisms.
