Abstract
Colon signet-ring cell carcinoma (SRCC) is a rare type of malignant dedifferentiated adenocarcinomas, and is associated with poor survival. However, an in-depth study of the biological features of SRCC is hindered by the lack of a reliable in vitro model of colon SRCC. Thus, the establishment of cell cultures from SRCC has become the most challenging task. Here, by harnessing the power of the organoid culture system, we describe the establishment of a human colon SRCC organoid line from a surgical sample from one patient with colon SRCC. The colon SRCC organoid line, YQ-173, was characterized for morphology, histology, ultrastructure and chromosome stability levels, showing that it resembles the histological and growth characteristics of the original tumor cells; xenografts were used to show that it also has a high tumor formation rate. RNA sequencing of YQ-173 compared with the normal tissue verified its mucinous nature. Capture-based targeted DNA sequencing combined with drug screening based on a bespoke 88 compound library identified that JAK2 might be a treatment target. An in vitro drug screening found that AT9283 and Pacritinib could be effective JAK2 inhibitors, which was consistent with the in vivo xenograft response. We report, for the first time, the establishment of an SRCC organoid line allowing in-depth study of SRCC biology, as well as a strategy to assess in vitro drug testing in a personalized fashion.

Differential effects of p53 on bystander phenotypes induced by gamma ray and high LET heavy ion radiation. LIFE SCIENCES IN SPACE RESEARCH 2014; 1:53-59. [PMID: 26432589 DOI: 10.1016/j.lssr.2014.02.003] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/04/2014] [Revised: 02/04/2014] [Accepted: 02/04/2014] [Indexed: 06/05/2023]
Abstract
High LET particle irradiation has several potential advantages over γ-rays such as p53-independent response. The purpose of this work is to disclose the effect of p53 on the bystander effect induced by different LET irradiations and underlying mechanism. Lymphocyte cells of TK6 (wild type p53) and HMy2.CIR (mutated p53) were exposed to either low or high LET irradiation, then their mitochondrial dysfunction and ROS generation were detected. The micronuclei (MN) induction in HL-7702 hepatocytes co-cultured with irradiated lymphocytes was also measured. It was found that the mitochondrial dysfunction, p66(Shc) activation, and intracellular ROS were enhanced in TK6 but not in HMy2.CIR cells after γ-ray irradiation, but all of them were increased in both cell lines after carbon and iron irradiation. Consistently, the bystander effect of MN formation in HL-7702 cells was only triggered by γ-irradiated TK6 cells but not by γ-irradiated HMy2.CIR cells. But this bystander effect was induced by both lymphocyte cell lines after heavy ion irradiation. PFT-μ, an inhibitor of p53, only partly inhibited ROS generation and bystander effect induced by 30 keV/μm carbon-irradiated TK6 cells but failed to suppress the bystander effect induced by the TK6 cells irradiated with either 70 keV/μm carbon or 180 keV/μm iron. The mitochondrial inhibitors of rotenone and oligomycin eliminated heavy ion induced ROS generation in TK6 and HMy2.CIR cells and hence diminished the bystander effect on HL-7702 cells. These results clearly demonstrate that the bystander effect is p53-dependent for low LET irradiation, but it is p53-independent for high LET irradiation which may be because of p53-independent ROS generation due to mitochondrial dysfunction.

APMIS 2013; 121:582-91. [PMID: 23489260 DOI: 10.1111/apm.12043] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2012] [Accepted: 10/09/2012] [Indexed: 12/19/2022]
Abstract
The aim of the study was to investigate the expression levels of 'NPM'/nucleophosmin/B23 and human epidermal growth factor receptor 2 (Her-2)/neu in gastric cancer (GC) and corresponding non-malignant tissues, correlation with their clinicopathological parameters and the relationship of nucleophosmin/B23 and Her-2/neu in the occurrence and development of GC. A total of 131 postoperative patients were examined for nucleophosmin/B23 expression by immuno-histochemistry and for Her-2/neu expression by fluorescence in situ hybridization with the median follow-up period of 38 months. The positive expression rates of nucleophosmin (NPM) in neoplastic tissues and adjacent gastric mucosa were 65.6% and 52.7%, respectively. Nucleophosmin/B23 levels were linked to more advanced tumor stages, poor prognosis, and likelihood of recurrence (p < 0.05). The Cox multivariate analysis indicated that the nucleophosmin/B23 expression was an independent indicator for tumor recurrence (p = 0.011). Of the total GC specimens 12.21% were positive for Her-2/neu, but whose expression was of no correlation with patients' survival. Patients who were positive for Her-2/neu also had high NPM expression levels (p = 0.0303). The results suggest that nucleophosmin/B23 is a favorable prognostic indicator for GC. But Her-2/neu has no relationship with the prognosis of GC. The combined clinical significance of nucleophosmin/B23 and Her-2/neu remains to be further investigated.
