Abstract: Abstract of thesis entitled Identification and characterization of cancer-related genes in esophageal squamous cell carcinoma Submitted by Fu Li For the degree of Doctor of Philosophy at The University of Hong Kong in June 2007 Esophageal squamous cell carcinoma (ESCC) is the sixth leading cause of cancer death worldwide and the fourth most common malignancies in China. Previous studies have shown that ESCC is a lethal disease caused by a combination of environmental and genetic risk factors. However, the genetic steps involved in carcinogenesis of ESCC are still unclear. This study aims to identify more ESCC-related genes and to characterize their roles in the tumorigenesis of ESCC. Deletion of chromosome 3p is common in ESCC, suggesting the existence of one or more tumor suppressor genes (TSGs) at this region. Single-nucleotide polymorphism (SNP)-mass spectrometry-genotyping (SMSG), was applied to investigate loss of heterozygosity (LOH) on 3p in 100 primary ESCC cases with 386 SNP markers. The accuracy of LOH frequency detected by SMSG was further validated by quantitative real-time PCR in five selected SNP loci and the results demonstrated that SMSG is a reliable tool for LOH screening. Four minimal deleted regions (MDRs) at 3p26.3, 3p22, i3p21.3 and 3p14.2 were identified. Absent and down-regulated expression of candidate TSGs from MDRs and other frequent LOH loci, including CHL1, APG7L, PCAF, RBMS3, PLCD1 and CACNA2D3, were detected in primary ESCC tumors and ESCC cell lines. Deletions of MDR-1, 2 and 4 correlated with both advanced tumor stage and poor differentiation in ESCC further strengthened the clinical relevance to these deleted regions. A potential TSG located at 3p22, Phospholipase C-δ1 (PLCD1), was subsequently characterized. Absent expression of PLCD1 was detected in 26/50 (52%) primary ESCCs and 4/9 (44.4%) ESCC cell lines, which was significantly associated with DNA- copy-number loss and promoter hypermethylation (P The majority of ESCC patients presented with advanced/metastatic disease upon diagnosis let us to identify new biomarkers for molecular tumor staging and prognostic evaluation. Differentially expressed proteins among different stages of primary ESCCs and their paired nontumorous tissues were compared by proteomics-based technology. Among 18 differentially expressed proteins, the expression levels of alpha-actinin 4 ii(ACTN4) and 67 kDa laminin receptor (67LR) progressively increased from stage I to III. Clinicopathological correlation study using TMA revealed that ACTN4 overexpression was significantly associated with advanced clinical stage and lymph node metastasis while 67LR overexpression was significantly correlated with advanced clinical stage. In summary, this study provided evidence that more ESCC-associated 3p

Abstract: Esophageal squamous cell carcinoma (ESCC), the major histological subtype of esophageal cancer, is one of the most common malignancies with poor prognosis in the world. Despite continued development of diagnosis and treatment, ESCC remains the sixth leading cause of cancer death worldwide. Current treatment regimens in ESCC are often characterized by ineffectiveness and poor selectivity. Therapeutic methods directed at cancer-associated genes or cancer stem cells (CSCs) may be effective approaches to cure this deadly cancer. Therefore, this study aims to identify specific ESCC-related genes and cancer stemness genes which help us to develop new targeted agents to achieving objective, long-lasting therapeutic responses in ESCC. To obtain an accurate overview of genetic changes occurring in ESCC patients, our group performed microarray-based mRNA expression profiling and high-throughout transcriptome sequencing (RNA-Seq) to compare differentially expressed genes between ESCC tumors and their corresponding non-tumorous tissues. Prostate stem cell antigen (PSCA) was considered to be a candidate of primary interest due to significantly reduced expression in both microarray and RNA-Seq data. In this study, we examined the role of PSCA on the pathogenesis of esophageal cancer. Our results showed that PSCA was frequently down-regulated in ESCC. Its expression was negatively regulated by transcription factor SOX5. Also, we provided evidence that down-regulation of PSCA was associated with poor clinical outcomes of patients with ESCC. Both in vitro and in vivo assays revealed that PSCA could arrest cell cycle progression and promote differentiation. To further elucidate the mechanism involved in biological function of PSCA, we performed co-immunoprecipitation and mass spectroscopy to identify proteins that associate with PSCA. This study found that RB1CC1, a key signaling node to regulate cellular proliferation and differentiation, interacted specifically with PSCA both in vitro and in vivo. Binding of PSCA and RB1CC1 in cytoplasm resulted in stabilization and translocation of RB1CC1 into nucleus and then further regulates the crucial cell cycle and differentiation genes. Furthermore, in order to identify the cancer stemness genes specifically expressed in CSCs of ESCC, we utilized gene expression analysis to profile 34 stemness-associated genes in ESCC specimens. Developmental pluripotency associated 4 (DPPA4), a well known pluripotent marker of stem cell, was considered as the best candidate. Our following histopathological study demonstrated that DPPA4 rigorously marked the rare CSCs, in contrast to core stemness factors (OCT4 and SOX2) and previous reported CSC markers (CD90 and CD44), which expressed in a large population of cancer cells. Moreover, the expression of DPPA4 was also found to have prognostic value in ESCC, as the appearance of DPPA4+ cells was significantly associated with poor differentiation, advanced stage and higher incidences of lymph node metastasis. Finally, our functional studies showed that ESCC cells expressing exogenous DPPA4 conferred an enhanced ability to initiate tumor, self-renew, resist chemotherapy and metastasize through lymphatic system. In summary, this study provide evidence indicating that novel tumor suppressor gene PSCA and cancer stemness gene DPPA4 may contribute to the development and pr
