Revealing the Selective Mechanisms of Inhibitors to PARP-1 and PARP-2 via Multiple Computational Methods
22 views | Jun 17 2020
Hongye Hu et al. provided new insights about how inhibitors specifically bound to PARP-1 over PARP-2, which might help facilitate the design of highly selective PARP-1 inhibitors in the future. [Read the Full Post]
Mechanism and Current Progress of Poly ADP-ribose Polymerase (PARP) Inhibitors in the Treatment of Ovarian Cancer
0 views | Jun 15 2020
Feiyue Zheng et al. highlighted the current research progress on PARP inhibitor resistance, which has become a challenge in clinics. [Read the Full Post]
CDK12-Altered Prostate Cancer: Clinical Features and Therapeutic Outcomes to Standard Systemic Therapies, Poly (ADP-Ribose) Polymerase Inhibitors, and PD-1 Inhibitors
20 views | Jun 01 2020
Emmanuel S Antonarakis et al. found that CDK12-altered prostate cancer was an aggressive subtype with poor outcomes to hormonal and taxane therapies as well as to PARP inhibitors. A proportion of these patients might respond favorably to PD-1 inhibitors, which implicated CDK12 deficiency in immunotherapy sensitivity. [Read the Full Post]
PARP and PARG Inhibitors in Cancer Treatment
28 views | May 28 2020
Dea Slade highlighted clinical performance of four PARP inhibitors used in cancer therapy (olaparib, rucaparib, niraparib, and talazoparib) and discussed the predictive biomarkers of inhibitor sensitivity, mechanisms of resistance as well as the means of overcoming them through combination therapy. [Read the Full Post]
Talazoparib in Patients With a Germline BRCA-Mutated Advanced Breast Cancer: Detailed Safety Analyses From the Phase III EMBRACA Trial
32 views | May 27 2020
Sara A Hurvitz et al. found that Talazoparib was associated with superior efficacy, favorable PROs, and lower HRU rate versus chemotherapy in gBRCA-mutated ABC. Toxicities were manageable with talazoparib dose modification and supportive care. [Read the Full Post]
Combination of PARP inhibitor olaparib, and PD-L1 inhibitor durvalumab, in recurrent ovarian cancer: a proof-of-concept phase 2 study.
35 views | May 15 2020
Lampert EJ et al. found that he PARPi and anti-PD-L1 combination showed modest clinical activity in recurrent ovarian cancer. Their correlative study results suggested immunomodulatory effects by olaparib/durvalumab in patients and indicate that VEGF/VEGFR pathway blockade would be necessary for improved efficacy of the combination [Read the Full Post]
Functional evaluation of five BRCA2 unclassified variants identified in a Sri Lankan cohort with inherited cancer syndromes using a mouse embryonic stem cell-based assay
35 views | May 13 2020
Sirisena N et al. highlighted the value of mouse embryonic stem cell-based assays for determining the functional significance of variants of unknown clinical significance and provide valuable information regarding risk estimation and genetic counseling of families carrying these BRCA2 variants. [Read the Full Post]
MiR-509-3 augments the synthetic lethality of PARPi by regulating HR repair in PDX model of HGSOC
85 views | Feb 11 2020
Sun C found that MiR-509-3 can sensitize ovarian cancer cells to Olaparib by impeding HR, which makes it a potential target in PARPi synergistic treatment. [Read the Full Post]
Synergistic lethality between PARP-trapping and alantolactone-induced oxidative DNA damage in homologous recombination-proficient cancer cells
94 views | Feb 10 2020
Wang H found that PARP trapping combined with specific pro-oxidative agents may provide safe and effective ways to broaden the therapeutic potential of PARP inhibitors. [Read the Full Post]
