Backman, Patrick N. M.S., Purdue University, May 2016. Alternative Regulation of MYC in Lung Cancer. Major Professor: Andrea Kasinski. Lung cancer is the leading cause of cancer deaths in the United States, accounting for 27% of all cancer induced deaths 1 . In an attempt to create a effective targeted therapy for the treatment of lung cancer, a strategy used to treat an activated Kras G12D/+ ;...
Retinal regeneration and repair are severely impeded in higher mammalian animals. Although Müller cells can be activated and show some characteristics of progenitor cells when injured or under pathological conditions, they quickly form gliosis scars. Unfortunately, the basic mechanisms that impede retinal regeneration remain unknown. We studied retinas from Royal College of Surgeon (RCS) rats a...
MicroRNA (miR)-200 family members (miR-200s) are frequently silenced in advanced cancer and have been implicated in the process of epithelial-to-mesenchymal transition (EMT). We previously reported that miR-200s were silenced through promoter methylation in acquired EGFR-tyrosine kinase inhibitor (TKI) resistant non-small cell lung cancer (NSCLC) cells harboring EMT features. In this study, we ...
Inflammatory stimuli clearly contribute to lung cancer development and progression, but the underlying pathogenic mechanisms are not fully understood. We found that the proinflammatory cytokine IL-1b is dramatically elevated in the serum of patients with non–small cell lung cancer (NSCLC). In vitro studies showed that IL-1b promoted the proliferation and migration of NSCLC cells. Mechanisticall...
Abstract INTRODUCTION Diffuse midline glioma (DMG) is the most lethal of all childhood cancers. LIN28B an RNA binding protein expressed in a variety cancers, which suppresses let-7 family microRNAs, turn plethora oncogenes. However, role DMG has not yet been explored. Therefore, we sought to determine pattern expression and potential function using rare cell lines. METHODS All studies were perf...
We examined the anti-cancer effects and molecular mechanism of simvastatin in human castration-resistant prostate cancer (CRPC) cells, particularly focused on LIN28B and its target molecule, let-7 microRNA (miRNA) among the various target genes of NF-κB. A human CRPC cell line (PC3) was used in the current study. Gene expression patterns were evaluated using real time-PCR and western blot analy...
PURPOSE Single-nucleotide polymorphism (SNP) markers within LIN28B have been reported to be related to the timing of pubertal growth. However, no study has investigated the frequency of genetic markers in girls with precocious puberty (PP) or early puberty (EP). This study aimed to determine the frequency of putative genetic markers in girls with PP or EP. METHODS Genomic DNAs were obtained f...
UNLABELLED Neuroblastoma is the most commonly diagnosed solid tumour outside the central nervous system in children. However, genetic factors underlying neuroblastoma remain largely unclear. Previous genome-wide association study indicated that lin-28 homolog B (LIN28B) might play an important role in the development of neuroblastoma and also contributed to its poor overall survival. With the p...
Mouse B cell precursors from fetal liver and adult bone marrow (BM) generate distinctive B cell progeny when transplanted into immunodeficient recipients, supporting a two-pathway model for B lymphopoiesis, fetal "B-1" and adult "B-2." Recently, Lin28b was shown to be important for the switch between fetal and adult pathways; however, neither the mechanism of Lin28b action nor the importance of...
Lin28 and Lin28b are related RNA-binding proteins that inhibit the maturation of miRNAs of the let-7 family and participate in the control of cellular stemness and early embryonic development. Considerable interest has arisen recently concerning other physiological roles of the Lin28/let-7 axis, including its potential involvement in the control of puberty, as suggested by genome-wide associati...
