MetabolomicsCDK4-driven ketogenesis rewires histone modification to promote leukemia

How ketogenic metabolites affect tumorigenesis, and whether ketone metabolism becomes deregulated in cancer cells, remain incompletely understood. Using T-cell acute lymphoblastic leukemia (T-ALL) as a model, we demonstrate that the ketone body β-hydroxybutyrate (BHB) is elevated in cancer cells ...

MetabolomicsCDK4/6 inhibitor-mediated cell overgrowth triggers an osmotic stress response and chronic p38MAPK activation to promote long-term cell cycle arrest

Cell size and the cell cycle are intrinsically coupled and abnormal increases in cell size are associated with senescence and permanent cell cycle arrest. The mechanism by which overgrowth primes cells to withdraw from the cell cycle remains unknown. We investigate this here using CDK4/6 inhibito...

MetabolomicsRBC Balanced Immuno-inflammatory Signatures Identify Advanced Breast Cancer Patients on CDK4/6 Inhibitors at Increased Risk of Progression and Death

Recent studies show red blood cell (RBC) plays an essential role in regulating immunity. Nevertheless, the association of immuno-inflammatory parameters, especially RBC balanced signatures, with survival outcomes and adverse events still require investigation for advanced breast cancer (ABC) pati...

TranscriptomicsExpression profile of BCR-ABL1-transformed, Cdk4 R24C, Cdk6 R31C cell lines
Cdk4 and Cdk6 are two related kinases that bind D-type cyclins and regulate cell cycle progression. Due to their relevance in cancer, Cdk4/6 inhibitors are currently in advanced clinical trials in multiple tumor types. Cdk4/6 are inhibited by INK4 proteins that exert tumor suppressing functions. To ...

MetabolomicsCell overgrowth potentiates osmotic and replication stresses to promote p38/p53/p21-dependent senescence
Abnormal increases in cell size are associated with senescence and cell cycle exit. The mechanisms by which overgrowth primes cells to withdraw from the cell cycle remain unknown. We address this question using CDK4/6 inhibitors, which arrest cells in G0/G1 and are licensed to treat advanced HR+/HER...

TranscriptomicsImpact of CDK4-deficiency on EM-BM-5-myc driven B-lymphoma
Impact of CDK4-deficiency on EM-BM-5-myc driven B-lymphoma By crossing mating CDK4 Knockout mice with EM-BM-5-myc mice,We found CDK4-deficiency enhances the EM-BM-5-myc induced B-lymphoma.We further to discover the molecular mechanism B-lymphoma cells form the cdk4+/+ EM-BM-5-myc and cdk4-/-EM-BM-...

TranscriptomicssiRNA profiling of human cell line IMR-32 at time point 0 and transiently transfected with siRNA against GFP, Cyclin D1 and CDK4 at time point 48 hours reveals the undifferentiated phenotype in neuroblastoma depends on Cyclin D1 and CDK4 activity
Genomic aberrations of Cyclin D1 (CCND1) and CDK4 in neuroblastoma indicate that dysregulation of the G1 entry checkpoint is an important cell cycle aberration in this pediatric tumor. Here we report that analysis of Affymetrix expression data of primary neuroblastic tumors shows an extensive over-e...

TranscriptomicsExpression data from vehicle or PD-0332991 treated human T-ALL lines
Cyclin D3 is critical hematopoiesis and loss of cyclin D3 leads to resistance to transformation of bone marrow progenitors by Notch1-IC. We used a small molecule targeting cyclin D3:CDK4/6 activity to study whether its inhibition is an effective therapeutic strategy. We analyzed T-ALL lines in vitro...

TranscriptomicsHTG EdgeSeq analysis of parental and CDK4/6i-resistant (Ribociclib or Palbociclib) T47D breast cancer cell clones
Do illuminate the vulnerabilities of CDK4/6i-resistant T47D breast cancer cells, we created CDK4/6i-resistant T47D cell clones through a gradual dose escalation protocol using the selective CDK4/6 inhibitors Ribociclib and Palbociclib. We then performed gene expression analysis targeting 2549 genes ...

ProteomicsAssessment of CDK4 as a serine kinase phosphorylating OGG1
The early studies showed the serine/threonine of OGG1 was phosphorylated by CDK4 in vitro, in our study, LC-MS/MS was performed, and Byonic engine was used to identify the precise site to be phosphorylated by CDK4.The present study discovered a high basal level of CDK4-mediated phosphorylation of OG...
