Roger Chammas, MD-PhD concluded his studies in Medicine (1988) and got his PhD degree in Biochemistry (1993) at Universidade de São Paulo, while working at the Ludwig Institute for Cancer Research (1989-1993). He specialized in Glycobiology at University of California, San Diego (1994-1997) and was a visiting researcher at Friedrich-Miescher Institute, Basel (1991), Harvard School of Public Health, Boston (1993), Universidade Federal de São Paulo (1998-1999) and Moffitt Cancer Research Center, Tampa (2011-2012). Chammas is presently Full Professor of Oncology at Faculdade de Medicina da Universidade de São Paulo, where he has been working since 2000. Chammas serves as chair of the Center for Translational Research in Oncology, a research unit for both basic and translational cancer research at Instituto do Câncer do Estado de São Paulo, a specialized institute for cancer management and oncology teaching and research associated with Universidade de São Paulo. Chammas serves as academic editor for Plos One and Anais da Academia Brasileira de Ciências. His major interests are in the area of Cancer Biology (Biochemistry and Cancer Cell Biology), focusing in tumor progression, carbohydrate-dependent tumor markers and tumor microenvironment, as targets for combination therapy and molecular diagnostics through imaging in cancers.

- Plan for use of the institutional overhead - ICESP, 2017, AP.RT.INST
Abstract
The vision of Instituto do Câncer do Estado de São Paulo is to constitute an Excellence Center for Total Cancer Care and Research. To reach this goal, it is critically necessary to invest in research and innovation. Our research activities are organized in order to favor the continued search for solutions to the problems experience by the cancer patient daily. (AU)
- The use if RNA-based nano formulations to improve the efficacy of breast cancer treatment and reduce therapy-induced cardiotoxicity, AP.R
Abstract
Chemotherapy and radiotherapy are extremely potent tools to treat breast cancer, but they cause several side effects. Doxorubicin is widely used to treat this disease, but its therapeutic effects are limited by cardiotoxicity. Strategies to increase its anti-tumor effect with a lower dose and diminish the side effects are extremely desirable. A potential candidate for this strategy is t...
- General plan for the application of the institutional overhead, 2016-2017, AP.RT.INST
Abstract
One of the aims of the Instituto do Câncer do Estado de São Paulo (ICESP) is to constitute an Excellence Center for Research in Oncology, which should be internationally recognized. Investment in research activities is therefore necessary. Research activities are coordinated by two administrative offices, clinical research facility and the center for translational research in oncology. ...
- Accumulation of PHB1 is a common cellular response to different stressing stimuli and protects melanoma cells from er stress and the cytotoxic agent cisplatin, PUB.ART
Abstract
Melanoma is responsible for most deaths among all skin cancers and conventionalchemotherapy fails because of the development of chemoresistance. We usedproteomic analysis to identify cellular responses that lead to the chemoresistanceof human melanoma cell lines to cisplatin. A systems approach to the proteomicdata indicated the participation of specific cellular processes such as oxida...
- Plans for application of the institutional overhead, 2014-2015, AP.RT.INST
Abstract
The Cancer Institute of the State of São Paulo agglutinates a growing group of researchers who interact in two dedicates centers for research within the Cancer Hospital: (i) the clinical research center and (ii) the Center for Translational Research in Oncology, constituted by research labs and core facilities. Investments in research areas will be performed, creating more structures fo...

- Remodeling of omega 3 and omega 6 polyunsaturated fatty acids in extracellular vesicles released by Melanoma cells: changed response to radiotherapy?, BP.PD
Abstract
Melanoma is considered one of the most aggressive types of Cancer. Its relevance is increasing, as its incidence has increased rapidly around the world and there is still no effective therapy for metastatic disease. The conventional therapies such as chemotherapy and radiotherapy have not been effective in most cases due to intrinsic/extrinsic resistance observed in Melanoma cells. In t...
- Involvement of PAFR activation during chemotherapy in the melanoma repopulation phenomenon, BP.MS
Abstract
One of the biggest challenges faced in cancer treatment is the process of tumor repopulation.In this process, cells that are refractory to therapy, are able to proliferate and reconstitute the tumor. Despite its clinical frequency and its contribution to treatment failure, the molecular and cellular events involved in this phenomenon are still poorly understood. The comprehension of the...
- Analysis of subpopulation of CD20 positive melanoma cells in response to chemotherapy agents, using radionuclide imaging, BP.DR
Abstract
Malignant melanoma is the most aggressive cancer among skin tumors. Both high tumor growth rate and high toxicity caused by the treatment contribute to the lower survival rate of melanoma patients, as compared with patients with other skin cancers. Although various drugs and molecules have been developed over the past few years, little efficiency was obtained in therapy so far. In this ...
- Development of aptamers and G5 PAMAM dendrimers for the in vivo diagnosis of M2 macrophages in tumor microenvironment, BP.PD
Abstract
Optical imaging is a noninvasive technique, with low cost, that uses visible light and the properties of photons to obtain detailed images of organs and tissues as well as smaller structures including cells and even molecules. It can be employed to disease prevention, diagnosis and treatment. Furthermore, optical imaging is favorable to multimodal imaging. It extends over a wide range o...

- Evaluation of PAFR activation in the survival response and chemoresistance of tumor cells exposed to hypoxia, BE.EP.MS
Abstract
Metastatic melanoma has been considered a clinical challenge due to its notorious chemoresistance. The understanding of molecular and cellular events that contributes to melanoma chemoresistance is important to improve current therapies and prevent tumor recurrence. Previous in vivo studies from our group showed that PAFR activation favors melanoma growth by protecting to cisplatin-indu...
- Development of peptides for the in vivo detection of M1 and M2 macrophages in the tumor microenvironment, BE.EP.PD
Abstract
The presence of high macrophage infiltration within solid tumors correlates with chemoresistance, metastasis, poor prognosis and shorter survival of patients. Strategies that can identify macrophages within the tumor microenvironment or reeducate these cells towards a proinflammatory phenotype can improve the therapies for cancer management. Macrophages are among the most abundant cells...
- Post-transcriptional regulation of PHB gene by RNA-binding proteins and microRNAs in human melanoma, BE.EP.PD
Abstract
Cutaneous melanoma is one epithelial tumor originates in melanocytes. This tumor represents 4% of malignant neoplasms of skin and it is considered an important public health problem because of its high progression to metastasis and treatment resistance. Previous studies of our group revealed the accumulation of prohibitin (PHB) in cell lines of human melanoma after treatment with cispla...
