Hpv Imprints In Western India: The Overlooked Criteria For Cancer Profiling, Ashi R. Thobias, Jayendra B. Patel, Prabhudas P. Patel

Research Symposium

Background: In India, HPV infection detection for cancer-typing has been largely evaded. Especially, data on prevalence of HPV types other than the highly prevalent HPV 16 and 18 are lacking, particularly from the western region. Thus, present study aimed to evaluate prevalence of HPV strains in three most prevailing cancers in India i.e. cervical, oral and oropharyngeal cancer.

Materials & methods: DNA was isolated from tissue samples of 400 cervical cancer cases, 127 oral cancer cases and 75 oropharyngeal cancer cases and endpoint PCR was performed using degenerative primers MY 09/11, GP 5+/6+ and CP I/II. TS-PCR was conducted to …

Investigation Of The Interactions Between The Dream Complex And Hpv16, Kevin Ko

Theses and Dissertations

According to the American Cancer Society, it has been estimated that in 2019 alone, there will be approximately 53,000 new cases of oropharyngeal cancers. Oropharyngeal cancers are the largest subset of head and neck squamous cell carcinomas (HNSCCs), which are the sixth most common cancer across worldwide populations. They, along with other HNSCCs, fall under a category of cancers known as Human papillomavirus (HPV)-associated cancers, and it has been found that upwards of 70% of these cancers can be attributed to high-risk HPV infections.

Specifically, the high-risk HPV gene, E7, plays a key role in relieving cell cycle repression by …


Regulation Of The Long Non-Coding Rna Fam83h-As1 By Human Papillomavirus In Cervical Cancer, Jamie Ann Barr Ph.D. Jan 2019

Regulation Of The Long Non-Coding Rna Fam83h-As1 By Human Papillomavirus In Cervical Cancer, Jamie Ann Barr Ph.D.

Graduate Theses, Dissertations, and Problem Reports

Non-coding RNAs (NcRNAs), such as long non-coding RNAs (lncRNAs) and microRNAs (miRNAs), have been found to be involved in a variety of critical biological processes, and dysregulation of ncRNAs have been involved with several human diseases including cancer.

High-risk human papillomavirus (HPV) infection is one of the first events in the process of carcinogenesis in cervical and a subset of head and neck cancers. The expression of the viral oncoproteins E6 and E7 is essential in this process by inactivating the tumor suppressor proteins p53 and Rb, respectively, in addition to their interactions with other host proteins and regulation of …


Molecular Mechanisms Of Dna Replication Initiation In Hpvs With Genetic Variations Leading To Cellular Carcinogenesis, Gulden Yilmaz Aug 2017

Molecular Mechanisms Of Dna Replication Initiation In Hpvs With Genetic Variations Leading To Cellular Carcinogenesis, Gulden Yilmaz

Graduate School of Biomedical Sciences Theses and Dissertations

Human papillomaviruses are a vast family of double-stranded DNA viruses containing non-carcinogenic and carcinogenic types, whose crucial differences remain unknown, except for the difference in the frequency of DNA replication. The human papillomavirus (HPV) E2 protein regulates the initiation of viral DNA replication and transcription. Its recognition and binding to four 12 bp palindromic sequences in the viral origin is essential for its function. Little is known about the DNA binding mechanism of the E2 protein found in HPV types that have low risk for oncogenicity (low-risk) as well as the roles of various elements of the individual binding sites. …
