Cinnamaldehyde is known to have the antitumor effects in vitro and in vivo. In this study, we showed a potent and irreversible cytotoxic activity of the Cinnamaldehyde derivative 2'-benzoyloxycinnamaldehyde (BCA) in human Squamous oral cell carcinoma cell, YD-10B. BCA induced YD-10B cell apoptosis in a dose-responsive manner. BCA-induced apoptosis was associated with corresponding increases in a series of key components in the mitochondria-mediated apoptosis pathways, followed by caspase cleavage and PARP activation. We also observed that BCA induced autophagy through Akt/mTOR pathway in YD-10B cells. BCA treatment increased LC3B-II expression, and induced the formation of autophagosomes and autophagic vacuoles. These experimental findings suggest that BCA is a potent inhibitor of cell proliferation in YD-10B cells and provide new insights about leading to the possible development of a new therapeutic agent.

A poor prognosis of oral squamous cell carcinoma (SCC) is partly due to the invasiveness and metastasis of the tumor. One of key elements in tumor invasion and metastasis in the degradation of extracellular matrix is tissue inhibitors of metalloproteinases (TIMPs). This study was performed to determine the expression of TIMP-1 and TIMP-2 of oral SCCs with regard to the histologic invasiveness and differentiation in 5 normal oral mucosa and 36 oral SCCs. The histologic invasiveness of oral SCCs were classified into 4 grades. The differentiation of oral SCCs was divided into 3 grades. The StreptAvidin-Biotin immunohistochemical process, using TIMP-1 and TIMP-2 monoclonal antibodies, was performed to determine the expression of TIMP-1 and TIMP-2. The expression of TIMP-1 was positive in 5 of 17 oral SCCs with weak invasiveness and was positive in 8 of 19 oral SCCs with strong invasiveness. The TIMP-1 expression did not increase significantly with respect to the invasiveness of oral SCCs (P>0.05). The expression of TIMP-2 was strongly positive in 5 out of 17 SCCs with weak invasiveness and was strongly positive in 15 of 19 SCCs with strong invasiveness. The TIMP-2 expression increased significantly with respect to the invasiveness of oral SCCs; the stronger the expression, the stronger the invasiveness (P<0.05). The expression of TIMP-1 and TIMP-2 did not increase significantly with respect to the histologic differentiation. We concluded that with respect to the invasiveness, the TIMP-2 expression increases significantly in oral SCCs but the TIMP-1 expression does not; and that with respect to the histologic differentiation, their expressions do not increase significantly. These results suggested that TIMP-2 can be used as a tool to evaluate the invasiveness of oral SCCs.

Background. Vitamin K (VK) is a fat-soluble vitamin and is known to have anticancer activity in various cancer cell lines. However, there is no report on the anticancer effect of VK2 in mucoepidermoid carcinoma cells. Methods. The effects of VK2 on anti-proliferative and apoptotic activity were recognized by the trypan blue exclusion assay, 4'-6-diamidino-2-phenylindole (DAPI) staining and Western blot analysis. Results. The results showed that VK2 decreased cell viability and induced apoptotic programmed cell death in MC3 cells evidenced by the cleavages of caspase3 and PARP. VK2 treatment clearly increased Bak and truncated Bid (t-Bid) compared with the control treatment whereas it did not alter other Bcl-2 family members. Conclusions. Overall, our results suggest that VK2 can be a good apoptotic inducer accompanied by the increase in Bak and Bid protein. VK2 may be a potent target of anticancer drug candidate for the treatment of oral cancer.

Lysyl oxidase (LOX) family, the copper dependent amine oxidase, oxidizes lysine residues in extracellular collagen and elastin. LOX increases the strength of the extracellular matrix and plays an important role in tumor development and metastasis. It has been reported that increased LOX protein and RNA are found in head and neck squamous cell carcinoma. Moreover some studies regarded LOX as a prognostic marker of oral and oropharyngeal squamous cell carcinoma. However there has not been any report on LOX expression of salivary gland tumors. Here, we investigated LOX expression in mucoepidermoid carcinoma (MEC) and adenoid cystic carcinoma (ACC) of salivary gland and compare it to those of pleomorphic adenoma (PA). We evaluated LOX expression in eighteen MEC, eighteen ACC and twenty PA cases by immunohistochemical examination. Whereas PA showed relatively low density of LOX expression, ACC revealed more cases that showing high staining intensities for LOX. Significantly increased LOX expression was found in the cases of ACC when compared to those of PA (P = 0.010).

Nasolabial cyst is a rare benign lesion which is located in nasolabial fold and alar nose. In spite of the low occurrence of nasolabial cyst, it is important to recognize the differential diagnosis of odontogenic or non-odontogenic lesions that can occur in anterior maxilla or alar region. The diagnosis of the lesion can be made by clinical, radiographic and histopathological findings. In this paper we report a rare case of nasolabial cyst in a 56-year-old woman and discuss the clinical presentation, differential diagnosis, and treatment in the light of the literature.

An 18 years old female patient suffered from cerebrovascular occlusive disease, moyamoya disease, showed a huge cyst in her left mandibular body in the radiological observation. The lesion was asymptomatic and found during routine dental check. She had no experience of traumatic injury on her jaw. The cystic lesion was ovoid with irregular scalloping margin and multilobular image, and occupied the whole marrow space of mandibular body with slight expansion of buccal cortical bone. During operation the lesion showed an empty space covered with grayish white fibrous tissue. The luminal fibrous tissue and underlying bony tissue were curettaged and examined pathologically. In the histological observation the lesion was a pseudocyst lined by thick fibrous tissue. Some large vessels underwent atherosclerotic change, exhibiting thickened vessel walls which were partly distorted with hemorrhage and thrombi, and some small capillaries were extremely dilated with hemorrhage and subsequently resulted in perivascular ischemic change with chronic vasculitis. This mandibular cystic lesion was finally diagnosed as simple bone cyst (SBC) associated with moyamoya disease differentially from aneurysmal bone cyst (ABC), traumatic bone cyst (TBC), periapical odontogenic keratocyst, and central giant cell granuloma. Therefore, it was presumed that the thromboembolic and atherosclerotic vessels of moyamoya disease might increase the hemodynamic pressure of mandibular bone marrow tissue and subsequently was able to induce SBC.
