GSK-3β could directly phosphorylate 4EBP1 and activate the mTORC1 downstream signaling cascades to enhance protein biosynthesis and cell proliferation in RCC cell lines independent of rapamycin sensitivity.
However, over the past decade, marked advances in the treatment of metastatic RCC have been made, with targeted agents including sorafenib, sunitinib, bevacizumab, pazopanib and axitinib, which inhibit vascular endothelial growth factor (VEGF) and its receptor (VEGFR), and everolimus and temsirolimus, which inhibit mechanistic target of rapamycin complex 1 (mTORC1), being approved.
The combination of lenvatinib, a multiple receptor tyrosine kinase inhibitor, plus everolimus, a mammalian target of rapamycin (mTOR) inhibitor, significantly improved clinical outcomes versus everolimus monotherapy in a phase II clinical study of metastatic renal cell carcinoma (RCC).
Tivozanib (Fotivda<sup>®</sup>) is an oral, potent and highly selective vascular endothelial growth factor receptor (VEGFR) inhibitor that has been approved in the EU, Iceland and Norway for the first-line treatment of adult patients with advanced renal cell carcinoma (RCC) and for adult patients who are VEGFR and mammalian target of rapamycin (mTOR) pathway inhibitor-naive following disease progression after one prior treatment with cytokine therapy for advanced RCC.
The mechanistic target of rapamycin (mTOR) inhibitors, everolimus and temsirolimus, have widened therapeutic options to treat renal cell carcinoma (RCC).
The objective of this study was to investigate whether the activity of the mTOR inhibitor temsirolimus against RCC could be enhanced by OGX-011, an antisense oligodeoxynucleotide (ODN) targeting the stress-activated chaperone clusterin.
We report the largest retrospective cohort of patients with mChRCC treated with TT and no significant difference between AA and mTOR inhibitors was observed for TTF and OS.
It has recently been approved by the European Medicines Agency (EMA) for first-line treatment of adult patients with advanced renal cell carcinoma (RCC) and for adult patients who are VEGFR and mammalian target of rapamycin (mTOR) pathway inhibitor-naive, following disease progression after one prior treatment with cytokine therapy for advanced RCC.
We here tested the potential anti-RCC activity by a novel mTOR kinase inhibitor WYE-687in vitro and in vivo.WYE-687 was cytotoxic and anti-proliferative to established RCC cell lines (786-O and A498) and primary human RCC cells.
Tivozanib received its first global approval in EU, Iceland, and Norway on 28 August 2017 for the first-line treatment of adult patients with advanced RCC and for adult patients who are VEGFR and mTOR inhibitor-naive following disease progression after one prior treatment with cytokines.
A significant early discovery in RCC was frequent inactivation of the Von Hippel Lindau gene in ccRCC, which ultimately led to the development of vascular endothelial growth factor and mammalian target of rapamycin inhibitors.
He had a past medical history of renal cell carcinoma and had just started treatment with temsirolimus, a mammalian target of rapamycin (mTOR) inhibitor.
The treatment landscape in advanced and metastatic renal cell carcinoma (RCC) is moving from the inhibition of tyrosine kinases (TKI) and the mammalian target of rapamycin (mTOR) inhibitors to specific immunooncology agents like immune checkpoint inhibitors (ICI).
In conclusion, resveratrol suppressed RCC viability and migration, and promoted RCC apoptosis via the p53/AMPK/mTOR‑induced autophagy signaling pathway.
We identified six patients with metastatic RCC who initially responded to mTOR inhibitor therapy and then progressed, and had pre-treatment and post-treatment tumor samples available for analysis.
Currently, targeted therapies including vascular endothelial growth factor (VEGF) and mammalian target of rapamycin (mTOR) inhibitors are widely used in the treatment of metastatic RCC.
The mammalian target of rapamycin (mTOR) pathway is a critical target for cancer treatment and the mTOR inhibitor everolimus (RAD001) has been approved for treatment of renal cell carcinoma (RCC).
