چکیده

Lung cancer remains the most prevalent malignancy and the primary cause of cancer-related deaths worldwide. Unique mutations patterns can be found in lung cancer subtypes, in individual cancers, or within a single tumor, and drugs that target these genetic mutations and signal transduction pathways are often beneficial to patients. In this study, we used the Ion Torrent AmpliSeq Cancer Panel to sequence 737 loci from 45 cancer-related genes and oncogenes to identify genetic mutations in 48 formalin-fixed, paraffin-embedded (FFPE) human lung cancer samples from Chinese patients. We found frequent mutations in EGFR, KRAS, PIK3CA, and TP53 genes. Moreover, we observed that a portion of the lung cancer samples harbored two or more mutations in these key genes. This study demonstrates the feasibility of using the Ion Torrent sequencing to efficiently identify genetic mutations in individual tumors for targeted lung cancer therapy.

Homozygosity Mapping and Targeted Sanger Sequencing Identifies Three Novel CRB1 (Cumbs homologue 1) Mutations in Iranian Retinal Degeneration Families

Background: Inherited retinal diseases (IRDs) are a group of genetic disorders with high degrees of clinical, genetic and allelic heterogeneity. IRDs generally show progressive retinal cell death resulting in gradual vision loss. IRDs constitute a broad spectrum of disorders including retinitis pigmentosa and Leber congenital amaurosis. In this study, we performed genotyping studies to identify...

Human Cancer Modeling: Recapitulating Tumor Heterogeneity Towards Personalized Medicine

Despite diagnostic, preventive and therapeutic advances, growing incidence of cancer and high rate of mortality among patients affected by specific cancer types indicate current clinical measures are not ideally useful in eradicating cancer. Chemoresistance and subsequent disease relapse are believed to be mainly driven by the cell-molecular heterogeneity of human tumors that necessitates perso...

Identification of a Novel Tumor-Binding Peptide for Lung Cancer Through in-vitro Panning

Tumor-targeted therapies are playing growing roles in cancer research. The exploitation of these powerful therapeutic modalities largely depends on the discovery of tumor-targeting ligands. Phage display has proven a promising high throughput screening tool for the identification of novel specific peptides with high binding affinity to cancer cells. In the present study, we describe the use of ...

Detection of Mutations in Exons 5 and 8 of Tumor Suppressor Tp53 Gene in Patients with Squamous Cell Carcinoma of Lung Hospitalized in Afzalipour Hospital, Kerman, Iran

Introduction: Despite improvements in the diagnosis and treatment of lung cancer in the past two decades, it has remained the most common cause of death from cancer worldwide. Among all genes that are mutated in lung cancer, TP53 located on chromosome 17P13/1 has a significant diagnostic and prognostic value. TP53 mutations have been extensively studied in lung cancer and TP53 mutational spectr...
