Objective: Interferon-${\gamma}$ (IFN-${\gamma}$) and signal transducers and activators of transcription (STATs) each play an important role in carcinogenesis associated with viral infection. Cervical cancer is almost invariably associated with infection by human papillomavirus (HPV), and previous studies suggested that dysregulation of the signal pathway involved in IFN-${\gamma}$ and STATs is associated. Our objective was to evaluate the association of SNPs in STAT2, STAT3, and IFN-${\gamma}$ with cervical cancer susceptibility in Chinese Han women in Hunan province. Materials and Methods: Genomic DNA was extracted from peripheral blood samples of 234 cervical cancer patients and 216 healthy female controls. STAT2 and STAT3 genotyping was performed using polymerase chain reaction-restriction enzyme (PCR-RE) analysis. IFN-${\gamma}$ genotyping was detected by PCR-amplification of specific allele (PASA). Results: For STAT2 rs2066807 polymorphisms, there was no significant difference of genotype distribution (P=0.827) and allele frequencies (P=0.830, OR=1.09, 95% CI: 0.51-2.31) between cases and controls. For STAT3 rs957970 polymorphisms, there was no significant difference of genotype distribution (P=0.455) and allele frequencies (P=0.560, OR=0.92, 95% CI: 0.71-1.20) between cases and controls. For IFN-${\gamma}$ +874A/T polymorphisms, there was no significant difference of genotype distribution (P=0.652) and allele frequencies (P=0.527, OR=1.12, 95% CI: 0.79-1.59) between cases and controls. Conclusion: These results suggest that polymorphisms in STAT2, STAT3 and IFN-${\gamma}$ genes are not likely to be strong predictors of cervical cancer in Han women in southern China.

Background: Public awareness/knowledge on oral and pharyngeal cancer (OPC), potentially malignant disorders (PMODs) and their risk factors is crucial for prevention and early detection of OPC and PMODs. Yet, there are no published data available on the awareness and knowledge of OPC and PMODs among people living in Far North Queensland, Australia. Materials and Methods: This study was conducted as a cross sectional survey. A self-administered questionnaire was designed and consisted of relevant questions to ascertain socio-demographic information, awareness and knowledge of OPC, PMODs and risk factors and questions on participant's exposure to risk factors and dietary history were also included. Survey was carried out at the Dental Clinic of the James Cook University School of Dentistry (JCU Dental), Cairns, Australia. Subjects above the age of 20 years (n=366) were randomly selected during the period from 31st July to 6th September 2013 and questionnaire was distributed to complete while they are waiting for treatment. Data analysis was carried out using SPSS version 21 and the chi -squared test was employed to compare groups. P<0.05 was considered statistically significant. Results: The study revealed that 52.3% of the respondents were aware of the existence of OPC but only 19.0% were aware of PMODs. Of those who were aware of oral cancer, 92% agreed or strongly agreed that smoking is a strong risk factor for OPC. Similarly a relatively high proportion of the respondents agreed or strongly agreed that tobacco chewing (84%), tobacco chewing with areca nut (68%), chewing areca nut alone (51%) and exposure to actinic radiation (71%) as risk factors. However, the results for alcohol intake, age, and HPV infection were found to be relatively poor with proportions 33%, 34%, and 23% respectively. Conclusions: This study revealed an alarming lack of awareness and knowledge of OPC and PMODs.

자궁경부암은 전 세계적으로 네번째를 차지하는 여성암이다. 자궁경부암의 대부분 원인은 인유두종 바이러스의 감염이다. 인유두종 바이러스를 검출하기 위해 다양한 분자진단학적 방법들이 고안되었다. 분자진단학적 방법 중의 real-time PCR은 목표 DNA 또는 RNA의 정량과 민감도 향상을 목표로 도입되었다. 특히, real-time PCR 과정은 수행 전에 RNA 추출 및 상보적인 DNA 합성 과정이 필요하다. 따라서 본 연구에서는 민감하고 적합한 상보적인 DNA 합성 키트를 알아보기 위해서 상보적인 DNA 합성에 이용되는 두 개의 상용화된 키트를 평가하였다. 자궁경부암 세포주에서 두개의 상보적인 DNA 합성 키트의 $R^2$과 효율성을 비교한 결과 차이가 없었다. 그러나 Invitrogen 키트보다 Takara 키트가 $10^2$ 및 $10^3$ SiHa 세포주에서 P<0.001를 나타내었고 $10^1$ 및 $10^2$ HeLa 세포주에서도 P<0.001를 나타내었다. 이를 통해 Takara 키트가 Invitrogen키트보다 민감도가 높음을 알 수 있었다. 또한 40개의 탈락세포검체의 8, 4, 2, 1 mL을 이용하여 상보적인 DNA 합성 키트를 비교한 결과 Invitrogen 키트보다 Takara 키트가 8, 4, 1 mL에서 P<0.01 및 0.5 mL에서 P<0.05을 나타내어 임상 검체를 이용하였을 때에도 Takara 키트가 Invitrogen 키트보다 민감도가 높음을 알 수 있었다. 본 연구는 적합한 상보적인 DNA 합성 키트를 확인하기 위해 수행되었으며, 상보적인 DNA 합성 키트가 real-time PCR 결과 다양성에 영향을 미친다는 것을 시사하였다.
