Project description:The associations between female inflammatory bowel disease (IBD) patients and human papilloma virus (HPV) infection and cervical neoplasia (dysplasia or cancer) were unclear. Especially there was no data for Chinese IBD population. So we investigated the incidence and risk factors of HPV infection and cervical neoplasia (dysplasia or cancer) in female IBD patient.

Project description:HPV-positive oral squamous cell carcinomas (OSCCs) are specific biological and clinical entities, characterized by a more favorable prognosis compared to HPV-negative OSCCs and occurring generally in non-smoking and non-drinking younger individuals. However, poor information is available on the molecular and the clinical behavior of HPV-positive oral cancers occurring in smoking/drinking subjects. Thus, this study was designed to compare, at molecular level, two OSCC cell lines, both derived from drinking and smoking individuals and differing for presence/absence of HPV infection.

Project description:Approximately 25% of all head and neck cancers (HNC), and up to 60% of oropharyngeal cancers (OPC) are associated with human papillomavirus (HPV), predominantly HPV16. HPV-associated OPC have better prognosis and a more favorable response to therapy as compared to HPV-negative tumors. Viral oncoproteins are capable of transforming primary human keratinocytes from either genital or oral epithelia in vitro and most likely play the same role in vivo, by disrupting cell-cycle regulatory pathways leading to a genetic progression to ano-genital cancer and OPC. However, the precise mechanisms by which HPV mediates malignant transformation of keratinocytes in the upper digestive tract epithelia are not entirely clear. HPV E7-mediated inactivation of pRb results in overexpression of p16INK4A, which is commonly used as a clinical surrogate marker for HPV positivity/activity. However, high p16INK4A alone has insufficient sensitivity and specificity as a biomarker of HPV positivity in different mucosal sub-sites of HNC. Therefore, increasing emphasis is being placed on the assessment of viral load and E7 oncogene expression, resulting in further classification of HPV positive OPC as HPV-active and HPV-inactive. Differences in risk factors, age of presentation, clinical behavior and gene expression profiles indicate that HPV-positive and HPV-negative tumors develop via different molecular mechanisms and are biologically distinct. This study aimed to compare the gene expression profiles of HPV-active, -inactive and -negative OPC and determine their biological differences. ANALYSIS 1: Three-condition, one-color experiment: HPV-active, HPV-inactive and HPV-negative oropharyngeal tumor samples. Biological replicates: 12 HPV Active tumors, 8 HPV Inactive tumors and 16 HPV Negative tumors.

Project description:Head and neck squamous cell carcinomas are heterogeneous neoplasms that show clinical and biological differences in association with the human papillomavirus (HPV). To provide adequate therapeutic strategies, biological and clinical characterization is essential to stratify patients based on prognostic and predictive factors. Reports on HNSCC are scarce in Mexico, thus in the present study, we analyze 414 cases of HNSCC, including those of the oropharynx (OPSCC), larynx (LASCC), and oral cavity (OCSCC). We determined the presence of HPV and p16 expression. Global expression profiles were analyzed with Affymetrix HTA 2.0 microarray in 25 selected cases HPV+/p16+ versus HPV-/p16-. In our study we analyze 25 samples derived from HNSCC patients. 18 samples were HPV-/p16- and 7 HPV+/p16+. We compared the HPV-/p16- versus the HPV+/p16+ and identified differentially expressed RNAs with a fold change greater than 1.5 or less than -1.5. These data were used to obtain 98 genes that are differentially expressed in absence of HPV. The present study offers information regarding clinical and molecular characteristics of HNSCC, both associated and unassociated with HPV, in Mexican patients.

Project description:Multiple HPV genotypes infection is frequently detected in HPV+ cervical lesions, however it is not well stablished how is the different viral interaction during the carcinogenic process. Here we carried out a comprehensive study to characterize the multiple HPV genome expression and integration by RNA-Seq analysis in 19 invasive cervical carcinomas with HPV coinfections. Analysis of tumoral DNA by a hybridization kit indicated multi-infection ranging from 2 to 6 different HPV genotypes, without a preferential species coinfection. The expression analysis showed that a single HPV genotype preferentially expressed its genome, might indicating a competition between the infecting virus. Finally, the search for HPV/human chimeric transcripts indicated integration from just one HPV in almost all samples, corroborating the expression findings.

Project description:Breast milk is a complex liquid that enriched in immunological components and affect the development of the infant immune system. Exosomes, the membranous vesicles of endocytic origin, are ubiquitously in various body fluids which can mediate intercellular communication. MicroRNAs (miRNAs), a well-defined group of non-coding small RNAs, in human breast milk are packaged inside exosomes. Here, we present the identification of miRNAs in human breast milk exosomes using deep sequencing technology. We found that the immune-related miRNAs are enriched in breast milk exosomes, and are resistant to the general harsh conditions. Four small RNA libraries in human breast milk exosomes from four healthy women (30 +/- 0.9 years old, primiparity) when the infant were aged at 60 days were sequenced.
