    1. CHK1 inhibitor SRA737 is active in PARP inhibitor resistant and CCNE1 amplified ovarian cancer

      [Paper-level Aggregated] PMCID: PMC11253285

      Evidence Type(s): Oncogenic, Functional

      Justification: Oncogenic: The text discusses the resistance mechanisms in tumor cells and the effects of specific treatments, indicating that the variants S3C and S4D may be involved in oncogenic processes related to PARPi resistance and tumor growth. Functional: The study assesses the functional impact of SRA737 and PARPi on cell growth and signaling pathways, demonstrating how these variants influence the response to treatment and cellular behavior.

      Gene→Variant (gene-first): CHEK1(1111):S3C PARP1(142):S4D

      Genes: CHEK1(1111) PARP1(142)

      Variants: S3C S4D

    2. To determine if the synergy observed in vitro for PARPi-resistant cells translated to in vivo efficacy, SRA737 and PARPi combination therapy was tested in five HGSOC PDX models. Two HR competent CCNE1 amplified HGSOC PDX

      [Paragraph-level] PMCID: PMC11253285 Section: RESULTS PassageIndex: 18

      Evidence Type(s): Predictive, Prognostic

      Justification: Predictive: The passage discusses the response to therapy involving SRA737 and PARP inhibitors (PARPi), indicating a correlation with treatment response in specific PDX models. Prognostic: The mention of a trending increase in survival with combination therapy compared to monotherapy suggests a correlation with disease outcome, although it did not reach statistical significance.

      Genes: 142

      Variants: S4D

    3. PARPi-resistant JHOS4 PR (BRCA1MUT), PEO1 PR (BRCA2MUT), FUOV1, and OVCAR3 (CCNE1amp) cells were further tested for the mechanism by which SRA737 and PARPi synergistically inhibit tumor cell growth. Parental PEO1 and JHO

      [Paragraph-level] PMCID: PMC11253285 Section: RESULTS PassageIndex: 15

      Evidence Type(s): Oncogenic, Functional

      Justification: Oncogenic: The passage discusses the mechanism by which SRA737 and PARPi synergistically inhibit tumor cell growth, indicating that the variant S3C is involved in tumor development or progression through its effects on cell lines with specific mutations. Functional: The passage describes how exposure to SRA737 results in specific phosphorylation changes in CHK1 and other proteins, indicating that the variant alters molecular or biochemical function related to tumor cell growth.
