Challenges of drug resistance in the management of pancreatic cancer [PDF]

open access: yes, 2010
The current treatment of choice for metastatic pancreatic cancer involves single agent gemcitabine or combination of gemcitabine with capecitabine and erlotinib (tyrosine kinase inhibitor).

Anticancer sensitivities and biological characteristics of HCT116 cells resistant to the selective poly(ADP‐ribose) glycohydrolase inhibitor

open access: yesFEBS Open Bio, Volume 16, Issue 5, Page 1020-1029, May 2026.
We analyzed alterations of PAR metabolism‐related proteins in PARG inhibitor‐resistant HCT116RPDD cells. Although PARG levels remained unchanged, HCT116RPDD cells exhibited reduced PARP1 and ARH3 expression and elevated PAR levels. Interestingly, HCT116RPDD cells exhibited slightly elevated intracellular NAD+/NADH and ATP levels. Our findings suggest a

Metabolic Dependencies in Pancreatic Cancer. [PDF]

open access: yes, 2018
Pancreatic ductal adenocarcinoma (PDA) is a highly lethal cancer with a long-term survival rate under 10%. Available cytotoxic chemotherapies have significant side effects, and only marginal therapeutic efficacy. FDA approved drugs currently used against

Pharmacology and clinical drug candidates in redox medicine [PDF]

open access: yes, 2015
SIGNIFICANCE Oxidative stress is suggested to be a disease mechanism common to a wide range of disorders affecting human health. However, so far, the pharmacotherapeutic exploitation of this, for example, based on chemical scavenging of pro-oxidant ...

NAD+‒circadian rhythm coupling in dementia

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract The circadian rhythm system and sleep coordinate whole‐body functions across the 24‐h cycle, yet these rhythms progressively deteriorate with neurodegenerative diseases, including dementia. Growing evidence indicates that nicotinamide adenine dinucleotide (NAD+) interacts with the circadian system through multiple molecular pathways and that ...

Regulation of Peripheral Molecular Clocks in Mammalian Tissues and In Vitro Skeletal Muscle Activation of AMP-Activated Protein Kinase via AICAR

open access: yes, 2014
Most organisms possess a common molecular machinery that governs cellular and tissue circadian rhythmicity through a roughly 24-hour transcription-translation feedback loop.

Isocitrate Dehydrogenase Mutations in Cancer: From Bench to Bedside Applications

open access: yesMedComm, Volume 7, Issue 5, May 2026.
Mutant isocitrate dehydrogenase affects multiple cancer types. Alterations in IDH1 and IDH2 result in abnormal enzyme activity, leading to the overproduction of D‐2‐hydroxyglutarate (D‐2HG). This metabolite disrupts cellular metabolism and epigenetic regulation, driving cancer initiation, progression, and metastasis.

Apoptotic gene expression in neuropathic pain [PDF]

open access: yes, 2008
Pain initiated or caused by a primary lesion or dysfunction in the nervous system is defined as neuropathic pain. It results from direct injury to nerves in the peripheral or central nervous system and is associated with several clinical symptoms ...

Association between Cigarette Smoking and Hypoxanthine Guanine Phosphoribosyltransferase Activity

open access: yesKaohsiung Journal of Medical Sciences, 2005
The aim of this study was to investigate the association between smoking behavior and hypoxanthine guanine phosphoribosyltransferase (HGPRT) activity. A cross-sectional study was performed of 82 men, including 38 non-smokers and 44 smokers.

Orotic Aciduria [PDF]

open access: yes, 2018
Orotic acid is an intermediate found in the pathway for pyrimidine synthesis. The mitochondrial enzyme dihydroorotate dehydrogenase (DHODH) catalyzes the production of orotic acid by the conversion of the compound dihydroorotate to orotic acid.
