We previously showed two members of the ING family, ING1 and ING3 as a tumor suppressor gene in head and neck cancer. Progress in human genome sequencing provided additional information of the new members of the ING family genes. ING4 is localized to chromosome 12p13.31 region and harbors the PHD domain highly homologous among ING family proteins. We(More)
Recurrent vulvovaginal candidiasis (RVVC) is defined as having four or more symptomatic vulvovaginal candidiasis (VVC) attacks within a year. This study aimed to investigate whether Human Dectin-1 Y238X Gene Polymorphism plays a role in RVVC pathogenesis. In order to examine and explore this aim, an experimental study was undergone. The clinical study(More)
C-kit is a trans-membrane receptor tyrosine kinase (RTK) encoded by the proto-oncogene KIT located at 4q11-12. Gain-of-function mutations arising to c-kit activation independent of its ligand were observed in various tumors related to germ cells, mast cells, and interstitial cells of Cajal. C-kit also participates in melanocyte development; hence, its(More)
The epidermal growth factor receptor (EGFR)-RAS-RAF-mitogen-activated protein kinase signaling cascade is an important pathway in cancer development and recent reports show that EGFR and its downstream signaling molecules are mutated in a number of cancers. We have analyzed 91 Japanese head and neck squamous cell carcinomas (HNSCC) and 12 HNSCC cell lines(More)
BACKGROUND Loss of heterozygosity (LOH) in the ING family members has been shown in head and neck squamous cell carcinoma (HNSCC) except for ING2. Like all the other members of ING family, ING2, which is located at chromosome 4q35.1, is a promising tumor suppressor gene (TSG). In this study, we performed LOH analysis of ING2 in HNSCC and compared it with(More)
The discovery of ING1 gene paved the way to the identification of other ING members (ING2-5) and their isoforms associated with cell cycle, apoptosis and senescence. The ING family has been an emerging putative tumor suppressor gene (TSG) in which the major mechanism is through interaction with the determinants of chromatin function and gene-specific(More)
BACKGROUND Squamous cell carcinoma is the most common cancer type of the oral cavity and approximately 50% of the patients succumb to the disease. Unfortunately, few are known about the molecular mechanisms involving in the formation of oral squamous cell carcinoma (OSCC). Recently, it has been reported that 1p36 chromosomal region is deleted in various(More)
Head and neck squamous cell carcinoma (HNSCC) is a frequent malignancy with a poor survival rate. Identifying the tumor suppressor gene (TSG) loci by genomic studies is an important step to uncover the molecular mechanisms involved in HNSCC pathogenesis. We therefore performed comprehensive analyses on loss of heterozygosity (LOH) using a genome-wide panel(More)
Our previous study showed high frequency of allelic loss at chromosome 2q37 region in oral cancer. This location contains several candidate tumor suppressor genes such as PPP1R7, ILKAP, DTYMK and ING5. We previously showed 3 members of inhibitor of growth (ING) family, ING1, ING3 and ING4 as tumor suppressor gene in head and neck cancer. As ING5 shows high(More)
Although many clinical and pathological prognostic factors such as tumor stage and lymph-node involvement have been described, to date no reliable or clinically applicable marker or tumor aggressiveness has been identified for head and neck cancer. In an attempt to identify such a molecular prognostic marker, we analyzed the mRNA expression status of ING3(More)
