Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Current Treatments and New Possible Complementary Therapies for Epithelial Ovarian Cancer

open access: yesBiomedicines, 2021
Epithelial ovarian cancer (EOC) is one of the deadliest gynaecological malignancies. The late diagnosis is frequent due to the absence of specific symptomatology and the molecular complexity of the disease, which includes a high angiogenesis potential ...

Membrane Fusion‐Mediated Cytosolic Delivery of Threose Nucleic Acids via Homotypic Nanoparticles Overcomes Drug Resistance in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study introduces a biomimetic “nanofusion” platform that integrates the biostability of threose nucleic acids (TNA) with homotypic cell‐membrane cloaking to combat drug‐resistant TNBC. By leveraging a non‐canonical membrane‐fusion pathway for direct cytosolic delivery, the platform bypasses endosomal sequestration. To achieve potent AKT2 silencing

Upfront maintenance poly(Adenosine Diphosphate Ribose) polymerase inhibitors in ovarian cancer: A ray of hope or just a mirage!

open access: yesIndian Journal of Medical and Paediatric Oncology, 2020
Poly(adenosine diphosphate ribose) polymerase inhibitors (PARPis), when used in patients harboring tumor with homologous recombination deficiency, with or without BRCA mutation, have shown favorable outcomes in relapsed, advanced metastatic breast and ...

Membrane‐Permeable Nucleoside T‐1106 Diphosphate and Triphosphate Analogues as Antiviral Pronucleotides

open access: yesChemistry – A European Journal, EarlyView.
Favipiravir (T‐705) and the non‐fluorinated counterpart (T‐1106) are antiviral agents that inhibit the RNA‐dependent RNA polymerase (RdRp) of various RNA viruses. The antiviral efficacy of nucleoside analogues is strongly dependent on their intracellular activation by cellular kinases to produce their corresponding triphosphate metabolites (T‐705‐RTP ...

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to

Inhibition of poly (adenosine diphosphate-ribose) polymerase attenuates lung-kidney crosstalk induced by intratracheal lipopolysaccharide instillation in rats

open access: yesRespiratory Research, 2013
BackgroundAcute respiratory distress syndrome (ARDS) is a severe form of lung injury that frequently occurs during pneumonia and sepsis. Lung inflammation in ARDS patients may have deleterious effects on remote organs such as the kidney.
