Cyclin-dependent kinase inhibitor 2A (CDKN2A) is a key regulator of cell cycle arrest and senescence in endothelial colony-forming cells (ECFCs) in moyamoya disease (MMD)
CONCLUSION: Our study suggests that CDKN2A plays an important role in the growth retardation of MMD ECFCs by inducing cell cycle arrest and senescence.PMID:37138505 | DOI:10.3340/jkns.2023.0005

MYC induces immunotherapy and interferon- γ resistance through downregulation of JAK2
Cancer Immunol Res. 2023 Apr 19:CIR-22-0184. doi: 10.1158/2326-6066.CIR-22-0184. Online ahead of print.ABSTRACTImmunotherapy has revolutionized the treatment of advanced melanoma. Because the pathways mediating resistance to immunotherapy are largely unknown, we conducted transcriptome profiling of pre-immunotherapy tumor biopsies from melanoma patients that received PD-1 blockade or adoptive cell therapy with tumor-infiltrating lymphocytes. We identified two melanoma-intrinsic, mutually exclusive gene programs, which were controlled by interferon-γ (IFNγ) and MYC, and the association with immunotherapy outcome. MYC-over...

Attenuation of cancer proliferation by suppression of glypican-1 and its pleiotropic effects in neoplastic behavior
Oncotarget. 2023 Mar 21;14:219-235. doi: 10.18632/oncotarget.28388.ABSTRACTGlypicans (GPC1-6) are associated with tumorigenic processes and their involvement in neoplastic behavior has been discussed in different cancer types. Here, a cancer-wide GPC expression study, using clinical cancer patient data in The Cancer Genome Atlas, reveals net upregulation of GPC1 and GPC2 in primary solid tumors, whereas GPC3, GPC5 and GPC6 display lowered expression pattern compared to normal tissues. Focusing on GPC1, survival analyses of the clinical cancer patient data reveal statistically significant correlation between high expression...

MDM2 promotes cancer cell survival through regulating the expression of HIF-1 α and pVHL in retinoblastoma
In this study, we investigated the role of MDM2 and its relation to HIF-1α in RB. Expression analysis on primary human RB samples showed that MDM2 expression was positively correlated with that of HIF-1α while negatively correlated with von Hippel-Lindau protein (pVHL), the regulator of HIF-1α. In agreement, RB cells with MDM2 overexpression showed increased expression of HIF-1α and decreased expression of pVHL, while cells with MDM2 siRNA knockdown or MDM2-specific inhibitor showed the opposite effect under hypoxia. Further immuno-precipitation analysis revealed that MDM2 could directly interact with pVHL and promotes...
