The return of metabolism: biochemistry and physiology of glycolysis

open access: yesBiological Reviews, EarlyView.
ABSTRACT Glycolysis is a fundamental metabolic pathway central to the bioenergetics and physiology of virtually all living organisms. In this comprehensive review, we explore the intricate biochemical principles and evolutionary origins of glycolytic pathways, from the classical Embden–Meyerhof–Parnas (EMP) pathway in humans to various prokaryotic and ...

Identification of a dihydropyridine scaffold that blocks ryanodine receptors

open access: yesiScience, 2022
Summary: Ryanodine receptors (RyRs) are large, intracellular ion channels that control Ca2+ release from the sarco/endoplasmic reticulum. Dysregulation of RyRs in skeletal muscle, heart, and brain has been implicated in various muscle pathologies ...

Natural occurence of a biopolymer, poly (adenosine diphosphate ribose)

open access: yesNucleic Acids Research, 1977
Evidence for the natural occurrence of poly(adenosine diphosphate ribose) in vivo was obtained using a sensitive radioimmunoassay and poly(adenosine diphosphate ribose) glycohydrolase, which specifically hydrolyzes poly(adenosine diphosphate ribose).

Targeting Genome Maintenance Defects of Cancers Using Chain‐Terminating Nucleoside Analogs

open access: yesCancer Science, EarlyView.
Nucleoside analogs interfere with DNA replication either by their chain‐terminating properties or by serving as DNA damage on the template. The genome maintenance pathways required to maintain cellular tolerance to each nucleoside analog vary depending on the drug.

Synthesis and calcium mobilization activity of cADPR analogues which integrate nucleobase, northern and southern ribose modifications [PDF]

open access: yes, 2012
Novel cADPR mimics, which integrate nucleobase, northern and southern ribose modifications were synthesized. The key steps of the synthesis were a Cu(I)-catalyzed Hüisgen [3+2] cycloaddition and a microwave-assisted intramolecular pyrophosphorylation ...

Demonstration of high molecular weight poly (adenosine diphosphate ribose)

open access: yesNucleic Acids Research, 1978
An electrophoretic system was established that resolves poly(adenosine diphosphate ribose), enzymatically synthesized polymer from NAD+, by size difference of one residue on polyacrylamide gel. The existence of a polymer of at least 65 residues was demonstrated by band counting in this system. The polymer showed a heterogeneous size distribution on the

Reprogramming SREBP1‐dependent lipogenesis and inflammation in high‐risk breast with licochalcone A: A novel path to cancer prevention

open access: yesInternational Journal of Cancer, Volume 158, Issue 7, Page 1927-1940, 1 April 2026.
What's new? Endocrine drugs repurposed from treatment protocols are the primary medications available for breast cancer (BC) prevention in at‐risk women. Adverse effects, however, significantly minimize uptake and prevention impact. Here, the authors investigated licochalcone A (LicA), a non‐endocrine anti‐inflammatory agent with reported hematologic ...

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.
