An oral environment is constantly exposed to environmental factors and microorganisms. The periodontal ligament (PDL) fibroblasts within this environment are subject to bacterial infection and allergic reaction. However, how these condition affect PDL fibroblasts has yet to be elucidated. PDL fibroblasts were isolated from healthy donors. We examined using reverse transcription-polymerase chain...

The high-risk human papillomaviruses (HPVs) are the causative agents of nearly all cervical cancers and are etiologically linked to additional human cancers, including those of anal, oral, and laryngeal origin. The main transforming genes of the high-risk HPVs are E6 and E7. E6, in addition to its role in p53 degradation, induces hTERT mRNA transcription in genital keratinocytes via interaction...

Scar formation following skin injury can be a major psychosocial and physiological problem. However, the mechanisms of scar formation are still not completely understood. Previous studies have shown that wound healing in oral mucosa is faster, associates with a reduced inflammatory response and results to significantly reduced scar formation compared with skin wounds. In the present study, we h...

OBJECTIVE Dental implants anchor in bone through a tight fit and osseo-integratable properties of the implant surfaces, while a protective soft tissue seal around the implants neck is needed to prevent bacterial destruction of the bone-implant interface. This tissue seal needs to form in the unsterile, oral environment. We aim to identify surface properties of dental implant materials (titanium...

Background: Human fibroblasts are the part of the dermis that secrete extracellular matrix for the purpose of tissue repair. Culturing fibroblasts, which leads to formation of a monolayer of these cells, is used for treating various conditions including thermal burns and other skin defects such as diabetic and varicose vein leg ulcers. Therefore, we aimed at developing a fibroblast bank to acco...

Proteinase-activated receptors 1 (PAR1) and 2 (PAR2) are the most highly expressed members of the PAR family in the periodontium. These receptors regulate periodontal inflammatory and repair processes through their activation by endogenous and bacterial enzymes. PAR1 is expressed by the periodontal cells such as human gingival fibroblasts, gingival epithelial cells, periodontal ligament cells, ...

Systemic sclerosis (SSc) is a connective tissue disease characterized by skin fibrosis and vasculopathy. Our original high-throughputin vitro screening method identified the aldose reductases (AR) inhibitor epalrestat as potential compound with antifibrotic activity among numerous commercial drugs. AR consist of aldo-keto reductase superfamily members, catalyzing NADPH-dependent detoxification ...
