In a pre-clinical animal model for bladder cancer, free particles were instilled in bladders with pre-established tumors.
The in vivo mouse model for bladder cancer is particularly well suited for T1- and T2-weighted MRI.
In this study we compared the regeneration of bladder tissue with a collagen-based biomatrix in a sheep model for bladder exstrophy with bladder tissue regeneration in normal bladder.
If further studies corroborate the important role of Capn3 in urothelial tumors of the urinary bladder, cattle with urinary tumors may prove useful as animal model for bladder carcinogenesis.
To date, the BOO model is the prominent model for bladder dysfunction, and other several pathologic models are in challenging state.
Using an animal model for bladder cancer, β-catenin was shown to induce tumorigenesis, and androgen-mediated AR signals appeared to synergize with β-catenin [ 93].
In a study using a transgenic model for bladder cancer, multiparous female mice developed significantly smaller tumors than nulliparous females [ 64].
Increasingly, superficial and invasive bladder cancers are regarded as distinct pathological entities and a two-pathway model for bladder tumour development has been proposed (see Lee and Droller, 2000 for review).
A threshold, sublinear, or hormetic model for bladder cancer and inorganic arsenic exposure has been proposed from toxicologic studies, based on a number of modes of action (Snow et al. 2005).
Using the full model, for bladder cancer, we find that three or more prereferral consultations were substantially more likely in women (OR=3.29 (2.06 to 5.25, p<0.001, table 4)) and less likely among those presenting with haematuria (OR=0.29 (0.19 to 0.46, p<0.001).
