The synthetic lethal association between BRCA deficiency and poly (ADP-ribose) polymerase (PARP) inhibition supports PARP inhibitor (PARPi) clinical efficacy in BRCA-mutated tumors. PARPis also demonstrate activity non-BRCA mutated tumors presumably through induction of PARP1-DNA trapping. Despite pronounced response, therapeutic resistance to inevitably develops. An abundance knowledge has been built around mechanisms tumors, however, parallel understanding settings remains insufficient. In...

To avoid the impact from background events directly $e^+e^-$ annihilations or $J/ψ$ decays, we propose a novel approach to investigate $η$ in particular for its rare forbidden by using $η^\prime\rightarrowππη$ produced decays at $τ-$charm factories. Based on MC studies of few typical $η\rightarrow ππ$, $γl^+l^- (l= e, μ)$, $l^+l^-$, as well $l^+l^-π^0$, sensitivities could be obviously improved taking advantage extra constraint $η^\prime$. Using one trillion accumulated Super $τ$-Charm...
