MicroRNAs down-regulate homologous recombination in the G1 phase of cycling cells to maintain genomic stability

open access: yeseLife, 2014
Homologous recombination (HR)-mediated repair of DNA double-strand break (DSB)s is restricted to the post-replicative phases of the cell cycle. Initiation of HR in the G1 phase blocks non-homologous end joining (NHEJ) impairing DSB repair.

Compensatory metabolic networks in pancreatic cancers upon perturbation of glutamine metabolism

open access: yesNature Communications, 2017
Glutaminase inhibition (GLSi) has promising activity against certain cancers. Here, the authors show that GLSi has no effect on multiple mouse models of pancreatic cancer and characterize the metabolic pathways activated in response to GLSi whose ...

Oncogenic KRAS supports pancreatic cancer through regulation of nucleotide synthesis

open access: yesNature Communications, 2018
Pancreatic ductal adenocarcinoma (PDAC) cells display varying degrees of reliance on oncogenic KRAS. Here the authors show that KRAS-resistant PDAC cells maintain nucleotides synthesis through a KRAS-independent upregulation of the non-oxidative pentose ...

NCOA4 maintains murine erythropoiesis via cell autonomous and non-autonomous mechanisms

open access: yesHaematologica, 2019
Ncoa4 mediates autophagic degradation of ferritin, the cytosolic iron storage complex, to maintain intracellular iron homeostasis. Recent evidence also supports a role for Ncoa4 in systemic iron homeostasis and erythropoiesis.

The Role of NCOA4-Mediated Ferritinophagy in Health and Disease

open access: yesPharmaceuticals, 2018
Nuclear receptor coactivator 4 (NCOA4) is a selective cargo receptor that mediates the autophagic degradation of ferritin (“ferritinophagy„), the cytosolic iron storage complex.
