The Role Of Ptip In Breast Cancer, Lina Niu

Theses, Dissertations and Capstones

In the U.S., breast cancer comprises about 30% of all cancer cases (excluding skin cancer) in women. Such a high incidence makes breast cancer a significant health concern, but our understanding of the molecular and cellular mechanisms of this disease is still limited. Growing evidence suggests that the development of human breast cancer may involve epigenetics, which attributes changes in phenotype to mechanisms other than changes in the DNA sequence itself. Histones as the chief proteins of chromatin work on gene expression, and methylation of histone 3 lysine 4 (H3K4) results in transcriptional activation. Lately, Paired box (Pax) trans-activation domain-interacting …

Redox Regulation Of Differentiation In Neuroblastoma, Anne Marie Silvis

Theses, Dissertations and Capstones

Neuroblastoma is the most common extracranial solid tumor in childhood, ranking third in prevalence among infant cancers. Despite intensive therapy with surgery, radiation and chemotherapy, there is a high chance of tumor recurrence. These children are therefore given retinoids in the maintenance phase to differentiate the tumor cells and to avoid/lessen this incidence. Although 13-cis retinoic acid (13-cis RA) is currently used to treat neuroblastoma, there is much evidence supporting the prevalence of its metabolite, all-trans retinoic acid (ATRA), to be the main signaling retinoid in vivo.

The SK-N-SH neuroblastoma cell line, which is composed of three sub-types: sympatheoadrenal neuroblasts …
