Introduction

Pluripotent stem cells (PSCs) have been useful to generate differentiated progenies for cell replacement therapy, and disease models. The Parkinson’s Disease (PD) field was arguably one of the first to have embraced the promise of stem cells. However, regardless of the differentiation protocols used, cultures and grafts continue to contain multiple cell types with midbrain dopamine (mDA) neural progenitors (NPs) and neurons representing only a fraction of total cells in the dish or graft. During cell differentiation, recruitment of transcription factors (TFs) to repressed genes in euchromatin is essential to activate new transcriptional programs, which is impeded by condensed …

Uveal melanoma is the most common primary intraocular malignant tumor in adults and arises from the transformation of melanocytes in the uveal tract. Even after treatment of the primary tumor, up to 50% of patients succumb to metastatic disease. The liver is the predominant organ of metastasis. There is an important need to provide effective treatment options for advanced stage uveal melanoma. To provide the preclinical basis for new treatments, it is important to understand the molecular underpinnings of the disease. Recent genomic studies have shown that mutations within components of G protein-coupled receptor (GPCR) signaling are early events associated …

OBJECTIVES

  • To define the mutant p53-regulated transcriptome of lung cancer cells with alterations at V157 and R158 in the p53 tumor suppressor.
  • To determine the biological effects of lung-enriched p53 mutations in lung cancer cells.
