Objective:
The objective of this study was to investigate the pattern of Twist expression in a series of ameloblastomas, and to study the possible role of Twist in the bone destruction and local invasiveness of ameloblastoma variants.
Study Design:
Immunohistochemical study was performed for Twist protein in 53 ameloblastomas (32 solid/multicystic [SA] and 21 unicystic [UA]).
Results:
The salient finding was that expression of Twist was related to the histological subtype of tumors, as there was a higher expression in SA (14/32, 43.75%) as compared to UA (4/21, 19.05%) (P < .05). Both nuclei and cytoplasm positivities were detected in positive cases, whereas cytoplasmic staining was diffused and predominant. Cases rich in stromal cells showed a higher percentage of positive cells than those with less stroma.
Conclusions:
Our results suggest that Twist expression might be associated with invasion in ameloblastoma variants, and stromal cells might play a regulatory role during tumor development.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
