the rare form of skeletal dysplasia is thanatophoric dysplasia. the meaning for thanatophoric dysplasia is death bearing which is derived from greek word. it occurs 1in 20,000 to 50,000. it is mainly due to mutations in the fibroblast growth factor receptor 3gene. features of thanatophoric dysplasia are frontal bossing, prominent eyes, narrow thorax, protruded abdomen and bowed legs. the knowle...
OBJECTIVE Mice homozygous for targeted deletion of the gene encoding fibroblast growth factor receptor 3 (FGFR3(-/-)) develop kyphoscoliosis by 2 months of age. The first objective of this study was to use high resolution X-ray to characterize curve progression in vivo and micro CT to quantify spine architecture ex vivo in FGFR3(-/-) mice. The second objective was to determine if slow release o...
PURPOSE The fibroblast growth factor receptor 3 (FGFR3) gene is known to be frequently mutated in noninvasive urothelial carcinomas of the bladder. In this study, we investigated the expression of FGFR3, Ki-67, and p53 in bladder cancers and the effects of expression on tumor recurrence. MATERIALS AND METHODS Fifty-five cases of primary bladder cancer were examined by immunohistochemistry. Th...
Radiotherapy resistance is the main cause of the the poor prognosis of some nasopharyngeal carcinoma (NPC) patients. Yet, the exact mechanism is still elusive. In the present study, we explored the clinical and biological role of protein arginine methyltransferase 5 (PRMT5) in NPC. Our results revealed that PRMT5 was overexpressed in NPC tissues when compared with that in adjacent non-tumor tis...
Gain-of-function mutations in fibroblast growth factor receptor-3 (FGFR3) lead to several types of human skeletal dysplasia syndromes including achondroplasia, hypochondroplasia and thanatophoric dysplasia (TD). Currently, there are no effective treatments for these skeletal dysplasia diseases. In this study, we screened, using FGFR3 as a bait, a random 12-peptide phage library and obtained 23 ...
Despite initial and sometimes dramatic responses of specific NSCLC tumors to EGFR TKIs, nearly all will develop resistance and relapse. Gene expression analysis of NSCLC cell lines treated with the EGFR TKI, gefitinib, revealed increased levels of FGFR2 and FGFR3 mRNA. Analysis of gefitinib action on a larger panel of NSCLC cell lines verified that FGFR2 and FGFR3 expression is increased at the...
Fibroblast growth factor receptor 3 (FGFR3) is amplified, translocated or mutated in a number of different human cancer types, but most commonly in bladder cancers. We previously found that the accumulation of FGFR3 is dependent on histone deacetylase 6 (HDAC6). Here we show that HDAC6 loss or inhibition reduces FGFR3 accumulation in cells made tumorigenic by ectopic expression of a mutant acti...
PURPOSE Mutations in the fibroblast growth factor receptor 3 (FGFR3) occur in 50% of primary bladder tumors. An FGFR3 mutation is associated with good prognosis, illustrated by significantly lower percentage of patients with progression and disease-specific mortality. FGFR3 mutations are especially prevalent in low grade/stage tumors, with pTa tumors harboring mutations in 85% of the cases. The...
BACKGROUND Aberrant activation of fibroblast growth factor receptor 3 (FGFR3) is frequently observed in bladder cancer, but how it involved in carcinogenesis is not well understood. The current study was aimed to investigate the underlying mechanism on the progression of bladder cancer. METHODS The GSE41035 dataset downloaded from Gene Expression Omnibus was used to identify the differentiall...
Abstract Introduction: Genetic variation of FGFR3 gene is one of the factors affecting the bladder tumor. FGFR3 is a tyrosine kinase receptor, involved in controlling the cellular and angiogenesis cycle. This protein affects a variety of diseases and cancers and cartilage growth abnormalities. Regarding the high activity of fgfr3 mutations in more than 50% of primary tumors of bladder urethral...
