The clinical impact of the expression of NOTCH1 signaling components in squamous cell carcinoma of the pharynx and larynx has only been evaluated in subgroups. The aim of this study was therefore to evaluate NOTCH1 expression in head and neck squamous cell cancer (HNSCC) patient tissue and cell lines. We analyzed tissue from 195 HNSCCs and tissue from 30 normal patients for mRNA expression of NOTCH1, NOTCH3, HES1, HEY1, and JAG1 using quantitative real-time PCR. Association of expression results and clinical orpathological factors was examined with multivariate Cox regression...

Polymorphous sweat gland carcinoma is an uncommon low-grade malignant adnexal tumor with a marked predilection for the distal extremities. Histologically, the lesions are characterized by a cellular proliferation showing a combination of growth patterns, including trabecular, solid, tubular, cribriform, or adenoid cystic and pseudopapillary. The immunohistochemical and molecular profile of these tumors has not yet been properly addressed. We have studied 3 cases of polymorphous sweat gland carcinoma using a broad panel of immunohistochemical markers including cytokeratin AE1/AE3, CK5/6, MOC31, p40, p63, p16, chromogranin, synaptophysin, CD56, MIB-1, estrogen receptor, progesterone receptor, androgen receptor, BER-EP4, smooth muscle actin, epithelial membrane antigen, carcinoembryonic antigen, CD117, S100 protein, HBME-1, DOG1, vimentin, and mammaglobin...

Cervical cancer is one of the main causes of female cancer death worldwide, and human papilloma virus (HPV) its causal agent. To investigate viral oncogenesis several studies have focused on the effects of HPV oncoproteins E6 and E7 and the mechanisms by which these proteins stimulate the cellular transformation process. However, phenomena such as the physical state of the viral genome (episomal or integrated) and the effects of this integration on cell proliferation contribute new clues to understand how HPV infection causes carcinogenesis...

Human papillomavirus (HPV) infections continue to be one of the most common sexually transmitted infections worldwide. The oncogenic potential of this virus was well established in anogenital malignancies and oropharyngeal cancers. Even though a fall in cervical cancer rates has been reported worldwide, the subsequent rise in HPV-associated head and neck cancers among men and women have been reported from developed countries, necessitating the vaccination of adolescent boys as well. The objective of this narrative review is to provide an update on the current status of HPV vaccination worldwide...

Verruca vulgaris is a common skin lesion that is associated with human papilloma virus and is observed on the surface of skin. Verruca vulgaris is rarely seen in mucosal membranes. Atypical locations may be confused with verrucous carcinoma. The incidence of laryngeal verruca vulgaris has not yet been reported in the literature. Differential diagnoses in histopathological examinations include keratosis, squamous papilloma, verrucous hyperplasia, and verrucous carcinoma. Distinguishing disease from verrucous carcinoma is particularly important because the treatment approach can be altered...

Epigenetic characterization studies have clearly shown that the association of genital Human Papilloma Virus (HPV) with cervical cancer is strong, independent of other risk factors, and consistent in several countries. Even though all the strains of Human Papilloma Virus can cause cancer, the high-risk strains can cause severe cancer in a human. The E6 and E7 protein are responsible for the carcinogenic property of HPV. Among these two proteins, the HPV E7 protein plays a major role in the viral life cycle by allowing the virus to replicate in differentiating epithelial cells...

Since the early 1800s vaccines have saved numerous lives by preventing lethal infections. However, during the past two decades, there has been growing awareness of possible adverse events associated with vaccinations, cultivating heated debates and leading to significant fluctuations in vaccination rates. It is therefore pertinent for the scientific community to seriously address public concern of adverse effects of vaccines to regain public trust in these important medical interventions. Such adverse reactions to vaccines may be viewed as a result of the interaction between susceptibility of the vaccinated subject and various vaccine components...

Human papilloma virus (HPV) is one of the most common viral sexually-transmitted diseases worldwide. The prevalence of HPV is higher in infertile males when compared with fertile men and ranges between 10 and 35.7% in men affected by unexplained infertility. HPV can bind to spermatozoa and can potentially be transferred to fertilized oocytes. Viral detection in blastocysts and trophoblastic cells is associated with impaired embryo development and poor pregnancy outcomes. Nevertheless, attempts to eliminate HPV-DNA from sperm samples through routine washing techniques have failed...

Papillomaviruses (PVs) are epitheliotropic viruses that cause benign proliferative lesions in the skin (warts or papillomas) and mucous membranes of their natural hosts. Recently, new PVs have been found in many animal species. The most common current approach for identifying novel PV types is based on PCR, using various consensus or degenerated primer (broad-range primers), designed on the basis of the multiple alignment of nucleotide or amino acid sequences of a large number of different human papillomaviruses (HPV)...

Head and neck squamous cell carcinoma (HNSCC), a heterogeneous group of upper aerodigestive tract malignancies, is the seventh most common cancer worldwide. Tobacco use and alcohol consumption were the most identified risk factors of HNSCC. However, human papilloma virus, a sexually transmitted infection, has been determined as another primary cause of HNSCC. Early-stage disease is treated with surgery or radiotherapy. Recurrent or metastatic HNSCC is associated with poor prognosis with a median overall survival of 10 months...

Anal squamous cell carcinoma (ASCC) is associated with infection with high-risk strains of human papilloma virus (HPV) in 70-90% of cases and a rise in incidence has been observed in the last decades. Definitive chemoradiotherapy (CRT) using 5-fluorouracil and mitomycin C constitutes the standard treatment for localized disease, but about 30% of patients do not respond or relapse locally. Phase I/II trials testing targeted agents, such as epidermal-growth-factor receptor (EGFR) inhibitors, have failed to improve clinical outcome and resulted in increased toxicities...
