Dynamic removal of replication protein A by Dna2 facilitates primer cleavage during Okazaki fragment processing in Saccharomyces cerevisiae [PDF]

, 2008
Eukaryotic Okazaki fragments are initiated by an RNA/DNA primer, which is removed before the fragments are joined. Polymerase d displaces the primer into a flap for processing.

MYC Binding Near Transcriptional End Sites Regulates Basal Gene Expression, Read‐Through Transcription, and Intragenic Contacts

Advanced Science, EarlyView.
MYC is a transcription factor (TF) that binds DNA near transcriptional start sites (TSSs) and within enhancer elements. Here, unappreciated sites of MYC binding in the vicinity of transcriptional end sites (TESs) of many genes in multiple cell types in association with numerous other TFs are described previously.

BAG2 Inhibits Cervical Cancer Progression by Modulating Type I Interferon Signaling through Stabilizing STING

Advanced Science, EarlyView.
Based on IP‐MS analysis, BAG2 is confirmed to be essential for ubiquitination and protein homeostasis regulation of STING in cervical cancer. BAG2 inhibits the ubiquitination and degradation of STING by forming a complex with STUB1, thereby activating the type I IFN signaling pathway and inhibiting the development of cervical cancer.

Quantitation of intracellular NAD(P)H can monitor an imbalance of DNA single strand break repair in base excision repair deficient cells in real time [PDF]

, 2003
DNA single strand breaks (SSBs) are one of the most frequent DNA lesions in genomic DNA generated either by oxidative stress or during the base excision repair pathways.

PSMD14 Stabilizes SLC7A11 to Ameliorate Glucocorticoid‐Induced Osteoporosis by Suppressing Osteocyte Ferroptosis

Advanced Science, EarlyView.
Glucocorticoid‐induced osteoporosis (GIOP) triggers osteocyte ferroptosis via SLC7A11 degradation. PSMD14 stabilizes SLC7A11 by counteracting glucocorticoid‐driven ubiquitination, preserving cystine uptake and glutathione synthesis. AAV‐mediated PSMD14 delivery or its agonist Pantethine rescues osteocyte survival and bone loss in GIOP mice.

Diallyl Trisulfide From Garlic Regulates RAB18 Phase Separation to Inhibit Lipophagy and Induce Cuproptosis in Hepatic Stellate Cells for Antifibrotic Effects

Advanced Science, EarlyView.
Diallyl trisulfides (DATs) selectively induce cuproptosis in hepatic stellate cells (HSCs) by targeting Ras‐related protein Rab‐18 (RAB18) and regulating lipophagy. DATs promote RAB18 phase separation, enhance mitochondrial‐associated membrane structures (MAMs) formation, and increase succinylation of dihydrolipoamide dehydrogenase (DLD) at K320.

In Vivo Reprogramming of Tissue‐Derived Extracellular Vesicles for Treating Chronic Tissue Injury Through Metabolic Engineering

Advanced Science, EarlyView.
Inspired by exercise‐induced metabolic rewiring and EV secretion, this study shows that in vivo metabolic engineering strategy can reprogram EV secretion pattern and simultaneously attenuate multiple tissue injury in CKD status, highlighting that it is a potential strategy for treating diverse chronic diseases.

ATP-dependent DNA ligases [PDF]

, 2002
By catalyzing the joining of breaks in the phosphodiester backbone of duplex DNA, DNA ligases play a vital role in the diverse processes of DNA replication, recombination and repair.

COPS5 Triggers Ferroptosis Defense by Stabilizing MK2 in Hepatocellular Carcinoma

Advanced Science, EarlyView.
COPS5, which is overexpressed in HCC in an amplification‐ and ATF4‐dependent manner, stabilizes MK2 through deubiquitination and, in turn, induces HSPB1 activation, protecting HCC cells from ferroptosis and thus promoting sorafenib resistance and tumor progression. Abstract Sorafenib, which is proven to serve as a potent ferroptosis inducer, is used as
