Temporomandibular joint osteoarthritis (TMJ-OA), a subtype of temporomandibular joint dysfunction (TMD), is characterized by progressive cartilage degradation, subchondral bone erosion, and chronic pain. Although there has been extensive research on TMJ-OA, its etiology remains unknown. Age, hormonal factors, and excessive mechanical stress on the TMJ are proposed risk factors for TMJ-OA.

View SamplesThe mucosal penetration area formed by implant placement is critical problems of dental implant treatment, because epithelial barrier is broken and it can become a source of inflammation. To clarify the influence and risk caused by dental implant treatment in peri-implant soft tissue, we compared to gene expression profile of peri-implant soft tissue and oral mucosal tissue with microarray analysis.

View SamplesThe peri-implant epithelium plays an important role in the prevention against initial stage of inflammation. In order to minimize the risk of peri-implantitis, it is necessary to understand the biological characteristics of the peri-implant epithelium. The aim of this study was to investigate the characteristic gene expression profile of peri-implant epithelium as compared to junctional epithelium using laser microdissection and microarray analysis.

View SamplesExcessive MS is known to result in disappearance of the alveolar hard line, enlargement of thePDL space, and destruction of alveolar bone, leading to occlusal traumatism. The regulatory role of MS is believed to play a critical role in the process of alveolar bone remodeling. However, little is known about the effect of excessive MS on expression of osteoclastogenesis-related genes in human PDL cells.

View SamplesHepatocellular carcinoma (HCC) is a heterogeneous disease with a variety of etiological factors, and ranks as the second leading cause of cancer-related mortality worldwide due to multifocal recurrence. Comprehensive molecular evaluation of HCC by multiplatform analysis defined three major subtypes: (1) mitogenic and stem cell-like tumors with chromosomal instability; (2) CTNNB1-mutated tumors displaying DNA hypermethylation; and (3) metabolic syndrome-associated tumors, which included an immunogenic subgroup characterized by macrophage infiltration and favorable prognosis. Although genomic and epigenomic analysis explicitly discriminated HCC with intrahepatic metastasis (IM) from multicentric HCC (MC), the phenotypic similarity between the primary and recurrent tumors was not linked to the IM/MC diagnosis, but rather the integrated classification. Thus, identification of these HCC subtypes provides insights into patient stratification and opportunities for therapeutic development.

View SamplesTongue squamous cell carcinoma (TSCC) varies in characteristics even in early stages and is mainly classified into three subtypes, which are superficial, exophytic and endophytic types, based on a macroscopic appearance of tumor growth.Of these subtypes, endophytic tumor has a poorer prognosis because of its invasive feature and higher frequency to have metastasis. To understand a molecular mechanism of endophytic subtype and identify biomarkers, we performed comprehensive microarray analysis for mRNAs from clinical biopsy sampleswhich were classified into subtypes and found overexpression of parvin-beta (PARVB) gene significantly related to endophytic type. PARVB is known to play a critical role in actin reorganization and focal adhesions. Knocking down PARVB expression in vitrocaused apparent decreases in cell migration and wound healing, implying that PARVB has a crucial role in cellular motility. Moreover, metastasis-free survival was significantly lowered in patients with higher PARVB expression. Therefore overexpression of PARVB is a candidate biomarker for endophytic tumor and metastasis and may be clinically applicable for decision making of an adjuvant therapy in TSCC.
PARVB overexpression increases cell migration capability and defines high risk for endophytic growth and metastasis in tongue squamous cell carcinoma.
