Objective:To evaluate the effect of down-regulation of RACK1 expression on growth and radiosensitivity of oral squamous cell carcinoma cells.Methods:The shRNA vector for RACK1 gene was constructed and transfected into HSC-3 cells by lipofectamine. The stably-transfected cell line was obtained by constructing G418. The expression levels of RACK1 mRNA and protein were detected by RT-PCR and Western blot. The cell proliferation was detected by CCK8 assay. Cell apoptosis was examined by flow cytometry. The invasive and metastatic capabilities of cancer cells were assessed by cell invasion assay in vitro.The effect of X-ray irradiation combined with down-regulation of RACK1 expression upon cell proliferation was assessed by clone formation assay. The xenograft tumor nude mouse model was established to observe the inhibitory effect of down-regulating RACK1 gene expression combined with X-ray irradiation on oral squamous cell carcinoma. Results:RT-PCR revealed that the expression level of RACK1 mRNA of transfected HSC-3 cells was significantly down-regulated ( P<0.05). Western blot showed that the expression level of RACK1 protein was significantly down-regulated ( P<0.05). CCK8 assay demonstrated that down-regulation of RACK1 expression could remarkably inhibit the growth of HSC-3 cells ( P<0.05). RACK1 gene shRNA interference combined with X-ray irradiation significantly enhanced the apoptosis rate of HSC-3 cells ( P<0.05). The number of invasion cells in vitro in the RACK1 silencing group was evidently decreased ( P<0.05). Clone formation assay showed that the survival fraction in the shRACK1 group was significantly lower than that in the control group. The sensitization enhancement ratio was 1.37(ratio of D 0 value). Xenograft tumor experiment in nude mice showed that tumor growth was significantly inhibited in the shRACK1 group, the tumor volume was significantly decreased and the tumor mass was significantly lower than those in the control group (all P<0.05). Conclusion:Down-regulating RACK1 expression can enhance the radiosensitivity of oral squamous cell carcinoma cells, providing novel thinking to improve the radiosensitivity of oral squamous cell carcinoma.

Objective To establish real-time PCR method for the detection of JAK2 V617F mutation and evaluate its clinical significance in patients with myeloprollferative disorders and leukemia.Methods 71 chronic myelocytic leukemia(CML) patients, 22 essential thrombocythemia (ET) patients, 11 primary myelofibrosis (PMF) patients, 9 polycythemia vera (PV) patients and 7 cosinophilia patients were enrolled in this study. JAK2 V617F mutation was determined by real-time PCR and amplification refractory mutation system (ARMS), followed by sequencing. Human erythroleukemia cell (HEL cell)DNA was used as homozygous control of JAK2 V617F mutation. The detection limit for either real-time PCR or ARMS was evaluated. Results Real-time PCR assay showed that there was a melting temperature(Tin) peak at (75.0±0.2)℃ for wild type samples and a Tm peak at (76.6±0.2)℃ for mutation type samples. JAK2 V617F mutation was detected in 8(88.9%) patients with PV, 12(54.5%) patients with ET and 7(63.6%) patients with PMF respectively. But there was only one positive case in 71 CML patient (1.4%). The results showed complete concordance with ARMS results and confirmed by sequencing. The mutation could be detected in 102 HEL cells per 106 white blood cells by real-time PCR, whereas the mutation can be assessed in 104 HEL cells per 106 white blood cells by ARMS. Thus, the sensitivity of real-time PCR was 100-fold higher than ARMS. Conclusions The real-time PCR method is successfully established for detection of JAK2 V617F mutation. This method is more sensitive, convenient than ARMS, and suitable for clinical application. There is high frequency of JAK2 V617F mutation in myeloproliferative disorders and it could be used as the diagnostic marker for myeloproliferative disorders.

Objective To investigate a new single nucleotid polymorphism (SNP) intron5(+4668C/T) in SLC22A12 in primary gout patients and the association between clinical characteristics and genotypes. Methods One hundred and one primary gout patients and 186 healthy subjects were recruited into this study. Blood pressure, body mass index (BMI) was recorded. Serum uric acid, glucose, lipid and creatinine were detected. DNA was extracted from peripheral blood to amplify the fragment located in intron 5. The genotypes of SLC22A12 can be detected with high-resolution melting (HRM) assay, followed by sequencing analysis. Chi-square test was used for statistical analysis. Results ① A new SNP in intron 5 of SLC22A12 was identi-fied successfully by HRM, which was defined as intron 5 (+4668C/T). CC, CT and TT genotypes were unam-biguously distinguished with HRM technology, which was fully concordant with sequencing. ②The genotypes of CC, CT and TT in male and female groups were 28.1%, 33.7%, 38.2% and 20.0%, 47.1%, 32.9%, respectively.③ However, no significant differences of genotype distribution were found concerning BMI, blood pressure, creatinine, total cholesterol and triglyceride in both male group and female group. But the serum uric acid levels in the CC genotype were significantly higher than those with the CT+TT genotypes. ④ The genotype frequencies of CC and CT+TT in high uric acid group were remarkably different from those in low uric acid group (21.2%, 78.8%,; 35.0%, 65.0%; P<0.05). Conclusion A new SNP has been successfully discovered with HRM technology with simplicity, rapidity and accuracy. T allele of intron 5 (+4668C/T) may be a genetic protective factor for hyperuricemia among Chinese population.

Objective To establish quantitative method for detection of methylation level of DLC-1 promoter with HRM technology to analyze its association with pathological parameters in prostate cancer.Methods 89 prostate cancer tissue samples and 10 matched normal tissue samples were enrolled into this study.Prostate cancer cells were obtained by LCM.DNA was extracted and modified for methylation determination.CpGenome Universal Methylated DNA was chosen as 100% methylation sample.Then the calibrators representative of 100%,80%,50%,30%,10% and 0% methylation levels were prepared with dilution in a DNA sample of peripheral blood from healthy subjects(100% non-methylation).The DLC-1 methylation levels in prostate cancer tissue samples were detected with HRM.The associations of methylated level with age of patients,PSA value,TNM stage were investigated respectively.ResultsThe melting curves representing 100%,80%,50%,30%,10% and 0% methylation levels were aligned from right to left.The methylation levels of 10 adjacent normal samples and 35 prostate cancer samples were overlapped with 0% methylated calibrator.The methylation levels of 5 cancer samples ranged between 0% and 30%.The methylation levels of 29 cancer samples ranged between 31% and 80%.The methylation levels of 20 cancer samples ranged between 81% and 100%.HRM could be used to reliably detect the as low as 10% methylation for each assay,whereas methylation specific PCR(MSP) could be used to detect 30% methylation level.No significant association between methylation level and patients' age(X~2=3.29,P=0.19),PSA level(X~2=2.04,P=0.36) was found.However,DLC-1 methylation was higher in the prostate cancer tissues with advanced TNM stage(X~2=9.04,P=.01).Conclusions The quantitative method for DLC-1 methylation with HRM is successfully established.It is convenient with good reproducibility and high sensitivity.DLC-1 methylation could be used as the molecular marker for estimation of malignancy in prostate cancer.
