Abstract
The intriguing molecular pathways involved in oral carcinogenesis are still ambiguous. The oral squamous cell carcinoma (OSCC) ranks as the most common type constituting more than 90% of the globally diagnosed oral cancers cases. The elevation in the OSCC incidence rate during past 10 years has an alarming impression on human healthcare. The major challenges associated with OSCC include delayed diagnosis, high metastatic rates, and low 5-year survival rates. The present work foundations on reverse genetic strategy and involves the identification of genes showing expressional variability in an OSCC case lacking addictive proclivities for tobacco, betel nut, and/or alcohol, major etiologies. The expression modulations in the identified genes were analyzed in 16 patients comprising oral pre-cancer and cancer histo-pathologies. The genes SCCA1 and KRT1 were found to down regulate while DNAJC13, GIPC2, MRPL17, IG-Vreg, SSFA2, and UPF0415 upregulated in the oral pre-cancer and cancer pathologies, implicating the genes as crucial players in oral carcinogenesis.

Abstract
Persistent infection with high-risk human papillomavirus (HPV) genotypes is the leading cause of cervical cancer development. To this end several studies have focused on designing molecular assays for HPV genotyping, which are considered as the gold standard for the early diagnosis of HPV infection. Moreover, the tendency of HPV DNA to be integrated into the host chromosome is a determining event for cervical oncogenesis. Thus, the establishment of molecular techniques was promoted in order to investigate the physical status of the HPV DNA and the locus of viral insertion into the host chromosome. The molecular approaches that have been developed recently facilitate the collection of a wide spectrum of valuable information specific to each individual patient and therefore can significantly contribute to the establishment of a personalised prognosis, diagnosis and treatment of HPV-positive patients. The present review focuses on state of the art molecular assays for HPV detection and genotyping for intra-lesion analyses, it examines molecular approaches for the determination of HPV-DNA physical status and it discusses the criteria for selecting the most appropriate regions of viral DNA to be incorporated in HPV genotyping and in the determination of HPV-DNA physical status.

Abstract
Background: Cervical cancer is one of the important reasons of mortality among females. Prevention, early diagnosis and immediate treatment can affect the rate of mortality in this cancer and several epidemiological studies have shown a strong relationship between human papilloma viruses (HPVs) and cervical cancer. Objectives: The present study was conducted to survey HPV infections in a women population with cervical cancer and cervical dysplasia/metaplasia in southwest of Iran. Materials and Methods: 72 paraffin-embedded cervical biopsies which had been previously archived from women with cervical cancer and cervical dysplasia were examined by polymerase chain reaction (PCR). Afterward, the detected HPV strains were typed by restriction fragment length polymorphism (RFLP) analysis of PCR amplicons. Results: 60 out of 72 samples had necessary requirements and HPV DNA was detected in 43.3% of these samples. Most HPV positive samples belonged to women aged from 48 to 63 years. On the other hand, HPV infection among patients with squamous cell carcinoma (SCC) was 48.78% and in women with dysplasia/metaplasia was 26.66%. The most prevalent type of the human papilloma virus was HPV16 (100%). Conclusions: Knowing the most prevalent type of the human papilloma viruses circulating in the population (HPV16) can be applied in the future screening and managing programs of this major disease and also in vaccination against the prevalent types of the virus. Meanwhile, it seems that more studies should be performed to determine the role of different risk factors involved in development of the disease, especially those related with social behaviors and traditions with respect to different areas.

Abstract
BACKGROUND Condyloma acuminatum (CA)-related human papillomavirus (HPV) typing has focused on the prevalence of HPV types. The correlation between HPV types and the clinical features of CA has rarely been documented. AIMS The purpose of this study was to investigate the relationship between HPV types and the clinical features of CA. METHODS Polymerase chain reaction-restriction fragment length polymorphism was used to type HPV in the CA lesions from 80 Chinese patients with full clinical data. RESULTS We determined that HPV6 and HPV11 single infections were the most frequent and accounted for 38.7 and 36.3%, respectively. Multiple infections caused by HPV6, HPV11, HPV16, HPV18, and/or HPV31 accounted for the remaining 25%. We were the first to document the HPV11 and HPV31 co-infection in a patient with colon carcinoma infected anal CA in China. The statistical analysis demonstrated that multiple HPV infections predisposed an individual to more warts, larger warts, a longer disease course, and a greater frequency of recurrence. The cases infected with the high-risk type, HPV16, accounted for 60% of the multiple infections and had a higher relapse rate than any other type of HPV infection. CONCLUSIONS Compared with a single HPV type infection, multiple HPV infections in CA were related to a more severe disease and a worse prognosis. These data provide useful information for the treatment and prognosis of CA. Mapping the proportion of CA caused by the virus types pre-vaccination enables the prediction of the vaccination benefits regarding CA burden reduction.

Abstract
Cervical carcinoma is one of the major consequences of human papillomavirus (HPV) infections. Although HPV infections of cervix do not always progress to cancer, 90% cases of cervical cancer have been found associated with high risk HPV (hrHPV) infection. Usually, HPV infection is asymptomatic; however, this asymptomatic infection can cause abnormal changes in cervix ultimately leading to cancer development. These changes can be detected by the application of screening tests at regular time intervals. For this purpose, morphological, cytological, and DNA based techniques are available. Nevertheless, abnormal screening tests have only the predictive value for precancerous lesions and thus require further evaluation which is usually done by using diagnostic techniques. So far, colposcopy and histological examination alone were considered as the gold standards for cervical cancer diagnosis. Currently, some tests based on expression level of host cell biomarkers are also being used along with histology for diagnostic purpose. Albeit, these tests have significant specificity and sensitivity values but they are unable to suggest a particular viral genotype involved in infection. Diagnostic methods such as PCR, HPV genotyping assays, microarray, and mRNA based assays are useful to predict the genotypes as well as the quantity of viral load in a host cell. Similarly, these diagnostic procedures have high specificity and sensitivity ranges. However, only few of them are practiced commonly, as approval of these tests as routine diagnostic tests requires clinical validation and cost effectiveness.

Abstract
Cervical cancer, the third most common cancer that affects women worldwide, is caused by the human papillomavirus (HPV) and is treatable when detected at an early stage. To date, more than 100 different HPV types have been described, and the development of simple, low-cost, and accurate methods to distinguish HPV genotypes is highly warranted. In this study, an HPV genotyping assay based on polymerase chain reaction (PCR) was evaluated. This method involved the use of MY09/11 primers followed by restriction fragment length polymorphism (RFLP) analysis with the restriction enzymes HpyCH4V and NlaIII. Cervical specimens preserved using CytoRich Blue fluid were collected from 1,134 female volunteers for HPV detection, and 1,111 valid samples were amplified using PCR. The PCR method was sensitive enough to detect 25 copies of HPV18, and three copies of HPV16. Out of 202 PCR-positive samples, HPV genotypes were determined in 189 samples (93.6%) by this RFLP method. Results were then evaluated further by capillary sequencing method. Concordant results between the two tests were as high as 96.0%. Thirteen samples, which tested negative with RFLP, were verified as non-specific amplifications with PCR. In conclusion, this PCR-RFLP method using restriction enzymes HpyCH4V and NlaIII is simple, non-labor intensive, and is applicable for the inexpensive determination of HPV genotypes in clinical samples.

Abstract
Human Papillomavirus (HPV) is the most common sexually transmitted virus. Worldwide, the most common high-risk (HR)-HPV are -16/18, and approximately 70% of cervical cancers (CC) are due to infection by these genotypes. Persistent infection by HR-HPV is a necessary but not sufficient cause of this cancer, which develops over a long period through precursor lesions, which can be detected by cytological screening. Although this screening has decreased the incidence of CC, HPV-related cervical disease, including premalignant and malignant lesions, continues to be a major burden on health-care systems. Although not completely elucidated, the HPV-driven molecular mechanisms underlying the development of cervical lesions have provided a number of potential biomarkers for both diagnostic and prognostic use in the clinical management of women with HPV-related cervical disease, and these biomarkers can also be used to increase the positive predictive value of current screening methods. In addition, they can provide insights into the biology of HPV-induced cancer and thus lead to the development of nonsurgical therapies. Considering the importance of detecting HPV and related biomarkers, a variety of methods are being developed for these purposes. This review summarizes current knowledge of detection methods for HPV, and related biomarkers that can be used to discriminate lesions with a high risk of progression to CC.

Abstract
BACKGROUND Due to the differences in the oncogenic activity of human papillomaviruses (HPV), it is clinically important to accurately identify HPV types in a simple and time effective manner. OBJECTIVES We aimed at developing a straightforward and cost-effective assay to individually identify all mucosal HPVs, based on the amplification of L1 gene using MY09/11 primers, and subsequent restriction fragment length polymorphism (RFLP) analysis. STUDY DESIGN We made use of bioinformatic tools to analyze all published DNA sequences of 49 mucosal HPV types for PstI, HaeIII, DdeI and RsaI restriction sites. Based on the RFLP patterns, we have designed an original genotyping algorithm. RESULTS Each HPV type presented a distinct RFLP pattern, which was visually distinguishable on polyacrylamide gels. A set of 27 pre-selected patient samples of known HPV types was confirmed positive for the same HPV type using this RFLP assay. Furthermore, in a random and blind HPV typing experiment performed in 30 untyped clinical samples, RFLP data consistently matched DNA sequencing results. CONCLUSIONS Our polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method, using 4 restriction enzymes (PstI, HaeIII, DdeI, RsaI) and an original genotyping algorithm, allows discrimination of all individual mucosal HPV types in single infections, and even detection of multiple infections. This assay gives complementary information to commercially available methods, and may also be financially advantageous, particularly when financial resources are scarce.

Abstract
BACKGROUND Restriction fragment length polymorphism (RFLP) methods for genotyping genital human papillomavirus (HPV) are considered labor consuming and constrained by the reduced set of restriction enzymes capable of detecting specific mutations. However, we think that these methods have not taken full advantage of the high diversity of the known restriction enzymes. OBJECTIVE We have set out to find the best restriction enzyme for HPV typing. STUDY DESIGN An extensive search for enzymes was carried out by combining statistical methods and database information. The search maximized the discrimination between high- and low-risk types by examining the sequence of the L1 gene flanked by primers MY09/11. Different electrophoretic resolutions and two variations of the RFLP method were considered. RESULTS HpyCH4V is the best enzyme for discriminating between risk types. Moreover, HpyCH4V generates different patterns for virtually all the HPV types. The typical pattern consists of two or three fragments, which facilitates typing in mixed infections. The typing of a set of clinical samples confirmed the expectations. CONCLUSIONS This result illustrates the possibilities of statistical methods to exploit the high diversity of restriction enzymes in order to classify samples in a pre-established hierarchy of types for which DNA sequences are known.
