Olaparib for patients with tumors harboring alterations in homologous recombination repair genes: Results from the drug rediscovery protocol

open access: yesInternational Journal of Cancer, Volume 158, Issue 6, Page 1617-1627, 15 March 2026.
What's new? PARP inhibitors are effective in patients with inactivating alterations in the BRCA1/2 genes across tumor types. However, the efficacy of PARP inhibitors in patients with other inactivated homologous recombination repair genes remains unclear. This knowledge gap and discrepancies in EMA/FDA approvals highlight the need for better biomarkers.

Hepatitis C Virus Nonstructural 5A Protein Inhibits Lipopolysaccharide-Mediated Apoptosis of Hepatocytes by Decreasing Expression of Toll-Like Receptor 4 [PDF]

open access: yes, 2017
Background. Hepatitis C virus (HCV) nonstructural protein 5A (NS5A) has been shown to modulate multiple cellular processes, including apoptosis. The aim of this study was to assess the effects of HCV NS5A on apoptosis induced by Toll-like receptor (TLR ...

The Problem of the "Prebiotic and Never Born Proteins"

open access: yes, 2012
It has been argued that the limited set of proteins used by life as we know it could not have arisen by the process of Darwinian selection from all possible proteins.

Exploring NAD(+) metabolism in host-pathogen interactions [PDF]

open access: yes, 2016
Nicotinamide adenine dinucleotide (NAD+) is a vital molecule found in all living cells. NAD+ intracellular levels are dictated by its synthesis, using the de novo and/or salvage pathway, and through its catabolic use as co-enzyme or co-substrate.

Molecular mechanisms of the non-coenzyme action of thiamin in brain. Biochemical, structural and pathway analysis [PDF]

open access: yes, 2015
Thiamin (vitamin B1) is a pharmacological agent boosting central metabolism through the action of the coenzyme thiamin diphosphate (ThDP). However, positive effects, including improved cognition, of high thiamin doses in neurodegeneration may be ...

Characterization of GDP-mannose Pyrophosphorylase from Escherichia Coli O157:H7 EDL933 and Its Broad Substrate Specificity

open access: yes, 2005
GDP-mannose pyrophosphorylase gene (ManC) of Escherichia coli (E. coli) O157 was cloned and expressed as a highly soluble protein in E. coli BL21 (DE3). The enzyme was subsequently purified using hydrophobic and ion exchange chromatographies. ManC showed

Ferrichrome identified from induces apoptosis through its iron-binding site in gastric cancer cells

open access: yesTumor Biology, 2017
Ferrichrome is known to be a siderophore, but it was recently identified as a tumor-suppressive molecule derived from Lactobacillus casei ATCC334 ( L. casei ). In the present study, we investigated the effects of ferrichrome in gastric cancer cells. Cell

Salvage enzymes in nucleotide biosynthesis [PDF]

open access: yes, 2007
Balanced pools of deoxyribonucleoside triphosphates (dNTPs), the building blocks of DNA, and ribonucleoside triphosphates (NTPs), the precursors of RNA, are crucial for a controlled cell proliferation.

Poly(Adenosine Diphosphate Ribose) Synthesis during Herpes Simplex Virus Infection

open access: yesIntervirology, 1979
Immediately after infection of baby hamster kidney cells with herpes simplex virus (HSV), cellular DNA synthesis was blocked, while extensive HSV DNA synthesis began. These dramatic alterations of the control mechanisms for these two DNA synthesizing systems were not accompanied by a change in the poly(adenosine diphosphate ribose) polymerase activity.
