Thymic stromal lymphopoietin (TSLP) is a key player in atopic diseases, which has sparked great interest in therapeutically targeting TSLP. Yet, no small-molecule TSLP inhibitors exist due to the challenges of disrupting the protein–protein interaction between TSLP and its receptor. Here, we report the development of small-molecule TSLP receptor in...

Background: Renal cell carcinoma (RCC) is a highly vascular tumor and patients with low risk metastatic RCC of clear-cell histological sub-type (mccRCC) are treated with tyrosine-kinase inhibitors (TKIs), sunitinib, as the first-line of treatment. Unfortunately, TKI resistance eventually develops, and the underlying molecular mechanism is not well...

Atopic diseases refer to common allergic inflammatory diseases such as atopic dermatitis (AD), allergic rhinitis (AR), and allergic asthma (AA). AD often develops in early childhood and may herald the onset of other allergic disorders such as food allergy (FA), AR, and AA. This progression of the disease is also known as the atopic march, and it go...

Objective: To identify the role of glioma-proteins (Gli) in sunitinib-resistant metastatic renal cell carcinoma and the effect of Gli-inhibition using a 3D tissue-engineered patient-derived model. Background: Renal cell carcinoma (RCC) is the 6th most common malignancy with 2.3% annual increase in Canada. Metastatic RCC (mRCC) patients are treated...

The sonic hedgehog (SHH) signaling pathway plays an integral role in the maintenance and progression of bladder cancer (BCa) and SHH inhibition may be an efficacious strategy for BCa treatment. We assessed an in‐house human BCa tissue microarray and found that the SHH transcription factors, GLI1 and GLI2, were increased in disease progression. A pa...

We have developed a murine intravesical orthotopic human bladder cancer (mio-hBC) model for the establishment of superficial urothelial cell carcinomas. In this model we catheterize female atyhmic nude mice and pre-treat the bladder with poly-L-lysine for 15 minutes, followed by intravesical instillation of luciferase-transfected human UM-UC-3 cell...

Introduction Clear-cell renal cell carcinoma (ccRCC) is the sixth most common malignancy in men in North America. Since ccRCC is a malignancy dependent on neovascularization, current first line systemic therapies like sunitinib, target the formation of new vessels allowing nutrient deprivation and cell death. However, recent studies have shown that...

Bone metastasis is an important prognostic factor in renal cell carcinoma (RCC). The calcium-sensing receptor (CaSR) has been associated with bone metastasis in several different malignancies. We analyzed the impact of CaSR in bone metastasis in RCC in vitro and in vivo. The RCC cell line 786-O was stably transfected with the CaSR gene and treated...

Background: The vast majority of prostate cancer presents clinically localized to the prostate without evidence of metastasis. Currently, there are several modalities available to treat this particular disease. Despite radical prostatectomy demonstrating a modest prostate cancer specific mortality benefit in the PIVOT trial, several novel modaliti...

Objective: Investigating the role of Y-box binding protein 1 (YB1) in drug resistant advanced kidney cancer. Background: Renal cell carcinoma (RCC) is the 6th most common malignancy with approximately 1,800 deaths in 2015 and 2.3% annual increase in Canada. Despite the partial or total surgical removal of kidney in patients with localized RCC, meta...
