The Protumorigenic Role Of Caspase-8 In Neuroblastoma, Devin Drew Twitchell
The Protumorigenic Role Of Caspase-8 In Neuroblastoma, Devin Drew Twitchell
Theses and Dissertations (ETD)
Neuroblastoma (NB), the most common extracranial solid tumor in children, accounts for 15% of cancer-related deaths in pediatric patients. Caspase-8 (casp8), a proapoptotic protein, is silenced in approximately, 50-70% of neuroblastoma patient samples. Loss of casp8 has been suggested to increase NB metastasis and correlated, in some studies, with advanced-stage NB. Furthermore, decreased casp8 expression may facilitate neuroblastoma tumorigenesis by protecting cells from cell death mediated by either integrins or chemotherapeutics. Paradoxically, casp8 expression is maintained in 30-50% of NB patient samples giving rise to the possibility that casp8 may provide selective advantages for NB tumorigenesis. Caspase-8 is shown to …

Effects Of Dna Damage And Cdk Inhibitors On The Nucleoli, Vineet Garg
Effects Of Dna Damage And Cdk Inhibitors On The Nucleoli, Vineet Garg
Theses and Dissertations
The nucleolus is the primary site of ribogenesis and consists of three compartments, namely, fibrillar center (FC), dense fibrillar component (DFC) and granular component (GC). Recent studies have observed a novel structure distinct from these three compartments which forms in the nucleolus upon DNA damage called Intranucleolar body (INoB). Previous studies in our laboratory have found INoBs forming in HT1080 fibrosarcoma cell lines after ectopic overexpression of damage-inducible cell cycle inhibitor p21. This INoB formation has been observed to be decreased by Senexin A which is an inhibitor of transcription regulating kinases CDK8/CDK19.
Here we show that INoB formation correlates …
