RNDr. Petr Vaňhara, PhD
We are curious:
- how normal and cancer cells exploit molecular machinery of endoplasmic reticulum and unfolded protein response to adapt to various forms of stress in tissue microenvironment
- if the integrated stress response can be used for monitoring and prediction of outcome of cancer patients
- how individual stress-associated proteins affect cancer cell phenotype
- state-of-the-art microscopy including live-cell imaging
- range of molecular and histological methods and tools
- animal facility, including ultrasound sonography and tumor volumometry
We develop techniques for:
