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]
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"
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]
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]
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 ...

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