EXO1 Facilitates MiDAS and Prevents Genome Instability and Cell Death in Ewing Sarcoma

This study identifies EXO1 as essential for Ewing sarcoma cell survival and shows its role in preventing genome instability and cell death by facilitating MiDAS.

XPF mediates 3' flap processing for FEN1-independent Okazaki fragment maturation

This paper shows that XPF degrades 3' flaps in human cells when FEN1 is deficient, enabling Okazaki fragment maturation and preventing DNA damage.

PARP1-mediated 5' flap dynamics facilitate Okazaki fragment maturation

This study identifies context-dependent roles of PARP1 in regulating Okazaki fragment maturation by controlling 5' flap dynamics and DNA ligation processes.

Oncometabolite fumarate impairs ATR-CHK1 signaling by succinating RPA1 in Fumarate Hydratase-deficient renal cell carcinoma cells

This study shows fumarate impairs ATR-CHK1 signaling by succinating RPA1, leading to defective DNA repair and cell cycle control in FH-dRCC.

DNA replication errors drive genome-wide small inverted triplication dynamics

The paper identifies DNA replication errors as a source of small inverted triplication (SIT) structural variants in yeast, showing their formation mechanism and characteristics.

Adaptive regulation of dNTP homeostasis confers osimertinib resistance in EGFR mutant non-small cell lung carcinoma

This study identifies dNTP homeostasis regulation as a mechanism of osimertinib resistance in EGFR-mutant NSCLC, revealing therapeutic targets through two regulatory axes.
