Inbred 129 strain mice are predisposed to developing male germ cell tumors (GCTs) of the testes. The inherent genetic defects that underlie male GCT susceptibility in the 129 mouse strain are unknown. GCT incidence is increased in 129 strain males that lack functional p53 protein, and we have used this finding to facilitate the generation of panels of GCT-bearing intercross and backcross mice f...
gressive tumors that account for 4.0-9.5% of all primary bone neoplasms (1, 2). GCT predominates in the long tubular bones, but does, in rare cases, occur in the small bones of the hands and feet. Most GCT cases occur at the sacrum, with only very rare cases occurring during pregnancy (3, 4). We report a case of a GCT involving a metacarpal bone with rapid growth during pregnancy, which was mis...
Granular cell tumor (GCT) is an infrequent benign neoplasm, which Abrikosoff accurately described in 1926. GCT probably has a neural crest cell origin. We present the clinical and imaging findings in a 45-year-old woman with a GCT involving the palate. CT and MR imaging revealed perineural tumor spread along the greater and lesser palatine nerves. We emphasize the peculiarity of the palatine lo...
Patients with complete XY gonadal dysgenesis (GD) show a high predisposition to germ cell tumors (GCT). Patients with coexistence of GCT and GD have been reported previously. Here we present a 15-year-old girl with mixed GCT and GD who also developed an intra-abdominal synovial sarcoma one year after the treatment. This is the first report, to our knowledge, of synovial sarcoma associated with ...
Giant cell tumor of bone (GCT) is the most commonly reported non-malignant bone tumor in Hong Kong. This kind of tumor usually affects people aged 20-40 years. Also, it is well known for recurrence locally, especially when the tumor cannot be removed completely. Filamins are actin-binding proteins which contain three family members, filamin A, B and C. They are the products of three different g...
Testicular germ cell tumors (GCT) are the most frequent malignancy in young adults and arise from intratubular germ cell neoplasia undetermined (IGCNU, also referred to as carcinoma in situ, CIS). To determine the transcriptional programs involved in the transition from normal germ cells to GCT, and to further elucidate genetic differences between seminomas and non-seminomatous GCT the global e...
Giant cell tumor of bone (GCT) is a destructive and potentially metastatic bone tumour in which the characteristic giant cells have classically been considered the culprits in bone destruction. However, the neoplastic element of the tumour consists of propagative osteoblast-like stromal cells that may play a role in bone resorption. The objectives of this study were to determine the expression ...
Gestational diabetes mellitus (GDM) is the most common metabolic disorder during pregnancy which is associated with 3 to 4 folds of increase in the risk of maternal and fetal morbidity, if it is not diagnosed early (1). Gestational diabetes occurs from 1% to 14%, and 90% of pregnancy-related diabetes has been related to gestational diabetes (2). Glucose challenge test (GCT) and glucose toleranc...
Giant cell tumor (GCT) of the bone also known as osteoclastoma typically arises from meta-epiphyseal region long and comprises 5% all tumors 20% benign tumors. Understanding pathogenesis is key to successful systemic therapy with denosumab, a RANK-ligand inhibitor. In this context, we report seven GCT bone-treated denosumab radiotherapy cases diverse clinical presentation our institute, NRS Med...
Individuals display dramatic differences in social communication even within similar social contexts. Across vertebrates dopaminergic projections from the ventral tegmental area (VTA) and midbrain central gray (GCt) strongly influence motivated, reward-directed behaviors. Norepinephrine is also rich in these areas and may alter dopamine neuronal activity. The present study was designed to provi...
