Conditional Reprogramming for Patient-Derived Cancer Models and Next-Generation Living Biobanks. Cells 2019; 8:E1327. [PMID: 31717887 PMCID: PMC6912808 DOI: 10.3390/cells8111327] [Citation(s) in RCA: 55] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/02/2019] [Revised: 10/14/2019] [Accepted: 10/25/2019] [Indexed: 12/21/2022] Open
Abstract
Traditional cancer models including cell lines and animal models have limited applications in both basic and clinical cancer research. Genomics-based precision oncology only help 2-20% patients with solid cancer. Functional diagnostics and patient-derived cancer models are needed for precision cancer biology. In this review, we will summarize applications of conditional cell reprogramming (CR) in cancer research and next generation living biobanks (NGLB). Together with organoids, CR has been cited in two NCI (National Cancer Institute, USA) programs (PDMR: patient-derived cancer model repository; HCMI: human cancer model initiatives. HCMI will be distributed through ATCC). Briefly, the CR method is a simple co-culture technology with a Rho kinase inhibitor, Y-27632, in combination with fibroblast feeder cells, which allows us to rapidly expand both normal and malignant epithelial cells from diverse anatomic sites and mammalian species and does not require transfection with exogenous viral or cellular genes. Establishment of CR cells from both normal and tumor tissue is highly efficient. The robust nature of the technique is exemplified by the ability to produce 2 × 106 cells in five days from a core biopsy of tumor tissue. Normal CR cell cultures retain a normal karyotype and differentiation potential and CR cells derived from tumors retain their tumorigenic phenotype. CR also allows us to enrich cancer cells from urine (for bladder cancer), blood (for prostate cancer), and pleural effusion (for non-small cell lung carcinoma). The ability to produce inexhaustible cell populations using CR technology from small biopsies and cryopreserved specimens has the potential to transform biobanking repositories (NGLB: next-generation living biobank) and current pathology practice by enabling genetic, biochemical, metabolomic, proteomic, and biological assays, including chemosensitivity testing as a functional diagnostics tool for precision cancer medicine. We discussed analyses of patient-derived matched normal and tumor models using a case with tongue squamous cell carcinoma as an example. Last, we summarized applications in cancer research, disease modeling, drug discovery, and regenerative medicine of CR-based NGLB.

Karatas OF. Antiproliferative potential of miR-33a in laryngeal cancer Hep-2 cells via targeting PIM1. Head Neck 2018; 40:2455-2461. [PMID: 30102806 DOI: 10.1002/hed.25361] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2017] [Revised: 03/21/2018] [Accepted: 05/17/2018] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Laryngeal cancer is a frequent cause of cancer-associated mortality worldwide with an overall poor prognosis along with high mortality rates. Therefore, comprehensive investigation of underlying molecular mechanisms of laryngeal carcinogenesis remains an important problem. METHODS In this study, proliferative and apoptotic features of Hep-2 cells overexpressing microRNA-33a (miR-33a) were evaluated and in silico analysis along with literature search was used to find putative targets of miR-33a. The potential of PIM1 (pim-1 oncogene) as a direct target of miR-33a was tested using quantitative real-time polymerase chain reaction, Western blot, and luciferase assay. RESULTS Induced miR-33a expression significantly inhibited proliferation through inducing apoptosis of Hep-2 cells. Further in vitro tests showed downregulation of PIM1 in messenger ribonucleic acid (mRNA) and protein level upon miR-33a overexpression and confirmed PIM1 as a direct target of miR-33a. CONCLUSIONS Mir-33a was demonstrated to act as a tumor suppressor in larnygeal cancer via directly targeting the 3' untranslated region of PIM1.

Association of periodontitis and human papillomavirus in oral rinse specimens: Results from the National Health and Nutrition Survey 2009-2012. J Am Dent Assoc 2017; 146:382-9. [PMID: 26025825 DOI: 10.1016/j.adaj.2015.01.019] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2014] [Revised: 01/20/2015] [Accepted: 01/20/2015] [Indexed: 01/22/2023]
Abstract
BACKGROUND Human papillomavirus (HPV)-positive oropharyngeal squamous cell carcinomas are increasing in incidence and are becoming significant public health concerns. Periodontitis is a chronic condition in which the affected tissue may facilitate oral HPV infection and persistence. The purpose of this study was to determine if an association of the presence of HPV in oral rinse specimens and periodontal disease exists. METHODS The authors combined the National Health and Nutrition Examination Survey (NHANES) data for years 2009-2010 and 2011-2012. The authors included participants aged 30-69 years who had clinically assessed periodontal and HPV data (n = 6,004). The authors analyzed the data using the Rao-Scott χ(2) test and logistic regression. RESULTS There were 498 participants who had the presence of HPV in oral rinse specimens. The adjusted odds ratio for the presence of HPV in oral rinse specimens with relation to periodontal disease was 1.04 (95% confidence interval, 0.63-1.73), adjusting for sex, race and ethnicity, education, age, income-to-poverty ratio, smoking, alcohol use, and number of sex partners during their lifetime. CONCLUSIONS The authors failed to reject the hypothesis of no association of the presence of HPV in oral rinse specimens and periodontitis. PRACTICAL IMPLICATIONS Although oral HPV infection is a serious concern, the authors found that periodontitis was not shown to be related to the presence of HPV in oral rinse specimens in adjusted analyses in this study.

Abstract
Our study aimed to identify the association between a PIM1 polymorphism and PIM1 expression levels with clinicopathological features of esophageal squamous cell carcinoma (ESCC). A total of 168 patients with ESCC were recruited as the case group, and 180 healthy individuals were included as the control group. Polymerase chain reaction-direct sequencing was employed to analyze all genotypes containing the PIM1 -1 882 A>T mutation. Immunohistochemistry was used to detect PIM1 expression. The distributions of genotype AA and allele A of PIM1 -1 882 A>T were higher in the case group than in the control group (both P<0.05). AT + TT carriers had a lower risk of ESCC than AA carriers (P<0.05). PIM1 polymorphism was related to the invasion depth, degree of differentiation, and lymphatic metastasis of ESCC (P<0.05). PIM1 expression was associated with lymphatic metastasis of ESCC and PIM1 polymorphism (both P<0.05). PIM1 -1 882 A>T and the overexpression of PIM1 were associated with the clinicopathological features of ESCC, and PIM1 -1 882 A>T may help to reduce the risk of ESCC in the Asian population.
