Heparin-binding protein 17 (HBp17)/fibroblast growth factor-binding protein-1 (FGFBP-1) was first purified from medium conditioned by A431 cells for its capacity to bind to fibroblast growth factors 1 and 2 (FGF-1 and -2). Among FGF family members, FGF-2 is a potent mitogen for various cell types, including vascular endothelial cells, fibroblasts, and cancer cells such as oral squamous cell carcinoma (OSCC) cells. Besides being well known in bone metabolism, the active form of vitamin D3, i.e., 1α,25(OH)2D3 (1,25D3), was reported to have protective effects for heart disease and cancer...

Continuous cell lines are widely used, but can result in invalid, irreproducible research data. Cell line misidentification is a common problem that can be detected by authentication testing; however, misidentified cell lines continue to be used in publications. Here we explore the impact of one misidentified cell line, KB (HeLa), on the scientific literature. We identified 574 articles between 2000 and 2014 that provided an incorrect attribution for KB, in accordance with its false identity as oral epidermoid carcinoma, but only 57 articles that provided a correct attribution for KB, as HeLa or cervical adenocarcinoma...

Aqueous extracts from the vegetative submerged mycelia of cultivated Basidiomycetes Ganoderma lucidum, Lentinus edodes, and Grifola frondosa, as well as from the fruiting bodies of G. lucidum, were found to have antitumor activity. The antitumor effect of the mycelial extracts from all 3 fungal species was ascertained in vivo in rats with implanted kidney cancer. Dystrophic changes in tumor cells and tumor necrosis (up to 90%) were noted. In vitro cytotoxicity studies of the A549 human lung adenocarcinoma cell line and HEp-2 human laryngeal epidermoid carcinoma cells showed that the extracts from the G...

Complete pharyngo-oesophageal stricture (PES) after radiotherapy for head and neck cancer is a relatively rare and difficult complication to manage. Historically this condition has been treated surgically, but endoscopic approaches are now available. We present a 61-year-old man with an epidermoid carcinoma of the supraglottic stage and a micro-invasive epidermoid carcinoma of the oropharynx treated surgically and subsequently by adjuvant radiotherapy. Eight months after the end of the radiotherapy, a complete PES was diagnosed and treated with a combined anterograde-retrograde endoscopic dilation (CARD)...

Squamous cell carcinoma is the most common carcinoma in the oral cavity. Resection of these cancers often requires reconstruction. Nasolabial flaps are a robust and reliable local flap that provide a satisfactory outcome. We report two cases where an epidermoid cyst developed within the scar of the nasolabial flap and review the literature.

Hyalinizing clear cell carcinoma (HCCC) is a rare salivary gland tumor with a specific EWSR1-ATF1 fusion gene and can have mucin production. Mucoepidermoid carcinoma (MEC) with a clear cell component is its morphologic mimic. Using MAML2 fluorescence in situ hybridization (FISH), a total of 49 MEC cases were separated into MAML2 fusion-positive (32 cases) and MAML2 fusion-negative groups (17 cases). This study used EWSR1 FISH to investigate MAML2 fusion-negative cases to identify previously unrecognized HCCC...

Concomitant radiotherapy and cetuximab association has shown superiority to exclusive radiotherapy for head and neck cancers. Data on this association are scarce for the elderly population despite its rising incidence. A retrospective monocentric data collection was performed in the Antoine Lacassagne Cancer Center in France. Inclusion criteria were: age >70 years at time of diagnosis, histologically proven head and neck epidermoid carcinoma, treated with radiotherapy combined with cetuximab. Thirty-five patients were included between 2008 and 2012...

Rosiglitazone (ROSI), an oral antidiabetic agent, has been reported the anti-cancer properties recent years. In this paper, the potency of ROSI as a synergistic drug for vincristine (VCR) on resistant oral cancer cells was investigated. We found that ROSI potently enhanced the susceptibility of KB cells or KB/V cells to VCR in a dose manner and the synergy in KB/V cells was much more prominent than that in KB cells. The synergistic anti-proliferative effect of ROSI and VCR was associated with inhibition on tubulin polymerization, cell cycle arrest in G2/M phase and cell apoptosis induction, but has no effect on drug efflux-protein P-gp and was independent with PPARγ...

Zearalenone is a β-resorcylic acid macrolide with various biological activities. Herein we report the synthesis and cytotoxic activities of 34 zearalenone analogues against human oral epidermoid carcinoma (KB) and human breast adenocarcinoma (MCF-7) cells as well as noncancerous Vero cells. Some zearalenone analogues showed moderately enhanced cytotoxic activities against the two cancer cell lines. We have discovered the potential lead compounds with diminished or no cytotoxicity to Vero cells. Preliminary structure-activity relationship studies revealed that the double bond at the 1' and 2' positions of zearalenone core was crucial for cytotoxic activities on both cell lines...

Understanding how the size of nanocarriers affects their fate in biological systems in vivo is of fundamental importance for rational design of drug delivery systems. In this study, five docetaxel (DTX)-loaded methoxy poly(ethylene glycol)-poly(lactide) micelles of different sizes (30-230nm) were prepared. It was observed that the permeation of micelles within both the multicellular tumor spheroids and tumor xenografts in mice was dependent on the size of the micelle. In addition, the size of micelles influenced their pharmacokinetic behavior...

We have previously reported that 1,25(OH)2D3 inhibits NF-κB activity and thus inhibits growth of OSCC cells in serum-free culture and down-regulates HBp17/FGFBP-1 expression, which is important for cancer cell growth and angiogenesis. Here, we have investigated the effects of ED-71, an analog of vitamin D3 (VD) on OSCC cell lines in serum-free culture. It is known that ED-71 has a stronger inhibitory effect on bone resorption compared to VD and other VD analogs. To the best of our knowledge, there was no report examining the potential of ED-71 as an anti-cancer agent for OSCC...
