  • Patent number: 9435001
    Abstract: The invention describes a consensus PCR based method (i.e. HRE7-PCR) for the simultaneous detection of 14 Human Papilloma Virus types (i.e. HPV 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, and 68) that are classified as (probably) high-risk, relating to the causation of cervical cancer) and a candidate hrHPV type (i.e. HPV 67) using sets of 6 overlapping forward primers and 9 overlapping backward primers that together amplify a fragment of about (215) to (245) base pairs of the E7 open reading frame of these hrHPV types. For the detection of reaction products an EIA format can be used with the aid of a cocktail of type-specific oligoprobes as exemplified herein. Furthermore, we have developed a method for an efficient typing of these (15) HPVs that is compatible with the method for detection. This RLB typing system involves hybridization of PCR products with immobilized type-specific oligoprobes.

  • Patent number: 9315866
    Abstract: The inventors now have developed a (molecular) diagnostic marker based on MAL alterations, in particular reduced MAL mRNA and protein expression as well as MAL promoter hypermethylation, to identify human papillomavirus (HPV)-induced high-grade precancerous lesions such as premalignant cervical lesions of invasive cervical cancer, and high-risk human papillomavirus (HPV)-induced precursor lesions of non-cervical invasive cancers within, cell material obtained via scraping, lavage or by other means and/or tissue. In particular, the present invention relates to the use of the MAL gene (including its promoter) and the gene products thereof as marker for HPV-induced high-grade premalignant lesions, allowing early detection and better treatment option for the individual patient.

  • Publication number: 20150225796
    Abstract: The inventors now have developed a (molecular) diagnostic assay based on detection of alterations in markers MAL and hsa-mi R124, in particular promoter hypermethylation, to identify human papillomavirus (HPV)-induced high-grade precancerous lesions such as premalignant cervical lesions of invasive cervical cancer, within cell material obtained via self-sampling. In particular, the present invention relates to the use of the MAL gene (including its promoter) and the hsa-mi R124 gene as marker for HPV-induced high-grade premalignant lesions, allowing early detection and a better treatment option for the individual patient.

  • Publication number: 20110171628
    Abstract: This invention describes new protocols for screening for cervical carcinomas or high-grade premalignant cervical lesions based on combinations of testing for the presence of high-risk HPV, HPV genotyping, marker analysis, and/or cytology. With these protocols the number of women that have to undergo follow-updiagnostic testing and/or clinical examinations will decrease. Further, the number of false positives and false negatives will decrease.

  • Patent number: 7501261
    Abstract: The invention is in the field of medicine and is concerned with a molecular diagnostic marker for progression to invasiveness of HPV-induced premalignant lesions and future metastatic potential of HPV-induced premalignant lesions and carcinomas. In particular the present invention relates to the use of the TSLC1 gene as marker for progression to invasive cervical cancer and metastatic potential of cervical lesions. The invention provides methods for detecting HPV-induced invasive cancers and their precursor lesions associated with tumor suppressor lung cancer 1 (TSLC1), comprising contacting a target cellular component of a test cell with a reagent that detects TSLC1 and detecting a reduction in the TSLC1 as compared to that of a comparable normal cell. The invention also provides molecular diagnostic markers for premalignant cervical lesions with invasive potential associated with tumor suppressor lung cancer 1 (TSLC1) in cytologically abnormal cervical smears and/or biopsies.
