26595804 ASPP1/2-PP1 complexes are required for chromosome segregation and kinetochore-microtubule attachments.
25660448 ASPP1/2 interacted with centrosome linker protein C-Nap1. Co-depletion of ASPP1 and ASPP2 inhibited re-association of C-Nap1 with centrosome at the end of mitosis.

23392125 ASPP1 and ASPP2 cooperate with oncogenic RAS to enhance the transcription and apoptotic function of p53.
23088536 When the Px(T)PxR motif is deleted or mutated via insertion of a phosphorylation site mimic (T311D), PP-1c fails to bind to all three ASPP proteins, ASPP1, ASPP2 and iASPP.
22552744 the mRNA expression of ASPP1 and ASPP2 was frequently dowregulated in tumor tissues, and this decreased significantly in samples expressing wild-type p53
22169642 ASPP1 promoter methylation may be associated with the malignant progression of non-small cell lung cancer, and ASPP1 expression promotes cellular apoptosis.
22068052 The ability of ASPP1 to activate YAP results in the decreased expression of LATS2, which lowers the ability of p53 to induce p21, cell-cycle arrest and senescence.
21479363 overexpression of ASPP1 rendered MCF-7 and MDA-MB231 breast cancer cells more sensitive to resveratrol-mediated apoptosis via the E2F pathway
21102414 Suggest that downregulation of ASPP1 by hypermethylation may be involved in the pathogenesis and progress of gestational trophoblastic disease, probably through its effect on apoptosis.
21041411 Data show that ASPP1 enhances nuclear accumulation of YAP/TAZ and YAP/TAZ-dependent transcriptional regulation.
21041410 Data show that Lats2 and ASPP1 shunt p53 to proapoptotic promoters and promote the death of polyploid cells.

20034025 ASPP1 and ASPP2 genes are frequently down-regulated by DNA methylation in HBV-positive hepatocellular carcinoma, which may play important roles in the development of HCC
16314841 results demonstrate that decreased expression of ASPP1 in patients with ALL is due to an abnormal methylation of its promoter and is associated with a poor prognosis
16139958 role of ASPP1, ASPP2, and iASPP as apoptotic specific regulators of p53 [review]
15782125 Mdm2 and mdmx prevent ASPP1 and ASPP2 from stimulating the apoptotic function of p53 by binding and inhibiting the transcriptional activity of p53.
15757645 ASPP1 CpG island aberrant methylation could be one molecular and genetic alteration in wild-type p53 tumours.
