Ionizing radiation is one of the most effective tools in cancer therapy. In a previous study, we reported that protein tyrosine kinase (PTK) inhibitors modulate the radiation responses in the human chronic myelogenous leukemia (CML) cell line K562. The receptor tyrosine kinase inhibitor, genistein, delayed radiation-induced cell death, while non-recepter tyrosine kinase inhibitor, herbimycin A (HMA) enhances radiation-induced apoptosis. In this study, we focused on the modulation of radiation-induced cell death by genistein and performed PCR-select suppression subtractive hybridization (SSH) to understand its molecular mechanism. We identified human thymidine kinase 1 (TK1), which is cell cycle regulatory gene and confirmed expression of TK1 mRNA by Northern blot analysis. Expression of TKl mRNA and TK1 enzymatic activity were parallel in their increase and decrease. TK1 is involved in G1-S phase transition of cell cycle progression. In cell cycle analysis, we showed that radiation induced G2 arrest in K

The prognostic significance of percentage of tumour involvement according to disease risk group in men treated with radical prostatectomy

引用

Asian Journal of Andrology 2011年第6期13卷 828-832页

作者： Jong Jin Oh Sang Cheol lee Chang Wook jeong Cheol Yong Yoon Seong Jin jeong Sung Kyu Hong Seok-Soo Byun Yoon Kwan Rho Gheeyoung Choe Sang eun lee Department of Urology Seoul National University Bundang Hospital Seongnam Kyunggi-do 463-707 Korea Department of Pathology Seoul National University Bundang Hospital Seongnam Kyunggi-do 463-707 Korea

We investigated the prognostic significance of percentage of tumour involvement （PTI） according to the clinicopathological features of prostate cancer among patients who underwent radical prostatectomy （RP）. A retrospective study of 534 patients who underwent RP between September 2003 and March 2008 without any neoadjuvant or adjuvant therapy was performed. The associations of PTI with various clinicopathological features and biochemical recurrence-free survival were examined via uni- and multivariate analyses. The predictive accuracy of the multivariate model was assessed with a receiver operating characteristics-derived area under the curve. PTI was demonstrated to be significantly associated with preoperative prostate-specific antigen （PSA） level （P=0.001）, pathological Gleason score （P〈0.001）, extraprostatic tumour extension （P〈0.001）, seminal vesicle invasion （P〈0.001） and positive surgical margin （P〈0.001） in univariate analyses. When patients were stratified into disease risk groups, PTI was an independent predictor of biochemical recurrence-free survival in multivariate analysis only among the low-risk group （P=0.033） but not the intermediate- （P=0.287） or the high-risk groups （P=0.828）. The addition of the PTI did not significantly increase the accuracy of the multivariate model devised for the prediction of biochemical recurrence-free survival among both total patients （P=-0.459） and the low-risk group （P=0.268）, respectively. In conclusion, although PTI appeared to be a more significant prognostic factor among patients with low-risk disease than among those with higher risk diseases, overall, the PTI may not provide additional prognostic information beyond what can already be obtained via established prognostic factors.

Dominance of Brassica and No Effects of Raphanus in Mature Seed Production in Intergeneric Hybrid between Brassica rapa ssp. Pekinensis and Raphanus

引用

American Journal of Plant Sciences 2022年第3期13卷 416-432页

作者： Soo-Seong lee Cho Yee Son eunsil Kim Hosub Shin jeong eun Park Seung Hwa Yu Jin Hoe Huh BioBreeding Institute Anseong Gyeonggi South Korea Department of Agriculture Forestry and Bioresources College of Agriculture & Life Science Seoul National University Seoul South Korea

We succeeded in producing mature seed from a line of Brassica rapa ssp. pekinensis that had been hybridized with Raphanus sativus var. major. Our focus was on dominance of B. rapa ssp. pekinensis;radish (R. sativus var. major) had no influence. Marker tests for similarity showed that the original CR291M-64 x HwiM-2 hybrid was an inbred CR291M-64, rather than a genuine cross;this appears to have resulted from weak self-incompatibility in this strain. The plants from the mature seed bloomed with reddish flowers differently shown up to present. The intergeneric hybrid between Brassica inbred and Raphanus hybrid was very weak in strength compared to the Brassica inbred which was self-pollinated even though the cause of the weak was not identified. The hybrids between Brassica hybrid, dominant and elite recessive, and Raphanus can be developed in large quantities using mature hybrid seed without resorting to ovule culture techniques.

Sojucktang induces apoptosis via loss of mitochondrial membrane potential and caspase-3 activation in KLE human endometrial cancer cells

引用

Chinese Science Bulletin 2009年第23期54卷 4387-4392页

作者： OH Yeon-Suk KWON Hee-Young jeong Soo-Jin PARK Ki-Young KIM Sun-Young lee Hyo-Jung lee Hyo-jeong lee eun-Ok AHN Kwang Seok KIM Sung-Hoon Cancer Preventive Material Development Research Center Oriental Medical CollegeKyunghee University College of Medicine Kyunghee University

Sojucktang (SJT) has long been used for the treatment of endometrial diseases in Korea. However, the mechanisms responsible for the SJT-induced apoptosis in endometrial cancer cells remain unclear. In the present study, SJT was demonstrated to show cytotoxic effect and induce apoptotic cell death via mitochondrial regulation in KLE endometrial cancer cells. Linderae Radix, Glycyrrhizae Radix, Zedoariae Rhizoma, Trogopterorum Faeces and Agelicae Gigantis Radix were found to be the potent constituent herbs of SJT to significantly decrease the viability of KLE cells by a tetra zolium salt (XTT) assay. Apoptotic bodies were observed in SJT-treated KLE cells by 4′-6-diamidino-2-phenylindole (DAPI) and TdT-mediated-dUTP nick-end labeling (TUNEL) assay. SJT also increased sub-G1 DNA contents of the cell cycle undergoing apoptosis in a dose-dependent manner. Furthermore, it was observed that SJT activated caspase-3 and cleaved poly (ADP-ribose) polymerase (PARP), and decreased mitochondrial membrane potential in a dose-dependent manner. Taken together, this study shows that SJT exerts anti-tumor activity against KLE endometrial cancer cells via mitochondrial dependent apoptosis induction.

Naturally occurring mutations in the reverse transcriptase region of hepatitis B virus polymerase from treatment-na?ve Korean patients infected with genotype C2

AIM To report naturally occurring mutations in the reverse transcriptase region(RT) of hepatitis B virus(HBV) polymerase from treatment na?ve Korean chronic patients infected with genotype *** Here, full-length HBV reverse transcriptase RT sequences were amplified and sequenced from 131 treatment na?ve Korean patients chronically infected with hepatitis B genotype C2. The patients had two distinct clinical statuses: 59 patients with chronic hepatitis(CH) and 72 patients with hepatocellular carcinoma(HCC). The deduced amino acids(AAs) at42 previously reported potential nucleos(t)ide analog resistance(NAr) mutation positions in the RT region were analyzed. RESULTS Potential NAr mutations involving 24 positions were found in 79 of the 131 patients(60.3%). Notably, AA substitutions at 2 positions(rt184 and rt204) involved in primary drug resistance and at 2 positions(rt80 and rt180) that functioned as secondary/compensatory mutations were detected in 10 patients(1 CH patient and 9 HCC patients) and 7 patients(1 CH and 6 HCC patients), respectively. The overall mutation frequencies in the HCC patients(3.17%, 96/3024 mutations) were significantly higher than the frequencies in the CH patients(2.09%, 52/2478 mutations)(P = 0.003). In addition, a total of 3 NAr positions, rt80, rt139 and rt204 were found to be significantly related to HCC from treatment na?ve Korean patients. CONCLUSION Our data showed that naturally occurring NAr mutations in South Korea might contribute to liver disease progression(particularly HCC generation) in chronic patients with genotype C2 infections.
