Dr Rosa María Sainz

Rosa M. Sáinz obtained her PhD at the Universidad de Oviedo. She was a postdoctoral fellow at the Instituto Universitario de Oncología de Asturias (IUOPA) from 2000 to 2001, before receiving a grant from the Fulbright-MEC programme to complete a postdoctoral fellowship at the Health Science Center in San Antonio (TX, US) between 2001 and 2004. She returned to the Universidad de Oviedo in 2005, where she worked as a Ramón y Cajal researcher until 2009 and she has been a Tenured Lecturer in Cell Biology since 2010.

Since then, Dr Sainz’s research has focused on the role of redox metabolism in cell survival and the signalling mechanisms involved in this process, as well as the acquisition of resistance phenotypes, and cell-differentiation mechanisms in tumour cells. These lines of research have been funded by public research bodies at the regional (Asturian Regional Research Plan), national (Instituto de Salud Carlos III Health Research Fund, Ministry of Economic Affairs and Digital Transformation) and international (JPI ERA-HDHL ).

She has authored over 90 publications in scientific journals, with over 10,000 cumulative citations, has a h-index of 42 and is one of the leading Spanish scientific authors in the field of Endocrinology and Metabolism. She is currently the academic secretary of IUOPA and is on the board of directors of the Sociedad Española de Biología Celular (Spanish Society of Cell Biology).

The main interest of the ‘Redox Biology and Metabolism in Cancer’ research group is exploring the role of reactive oxygen species as physiological agents in cell signalling mechanisms within biological processes.

1 - Redox Signalling in Processes of Cell Differentiation and Cell Death

The physiological levels of reactive oxygen and nitrogen species form part of a complex system of basic intracellular signalling which, by modifying cysteine residues from a wide range of proteins, participates in an intricate signalling system that regulates the activity of proteins such as kinases, proteases and transcription factors, which control the most essential cellular mechanisms.

The specific objectives of this line of research are to:

  • Determine how the proteins involved in redox homeostasis participate in cell survival mechanisms.
  • Evaluate the extent to which neuroendocrine differentiation mechanisms can act as a stress-response strategy which makes the tumour cells resistant to therapy.
  • Identify the role of H2O2 as a cell signaller in the cell-differentiation mechanisms of stem cells belonging to the spermatogenic series, and its involvement in fertility-related problems.
2 - Redox Control of Tumour Progression

Metabolic alterations of tumour cells, the infiltration of tumours by inflammatory cells and oncological treatments can all contribute to raising the levels of oxidative stress. The toxic effects of oxidative stress on normal cells can be avoided by boosting antioxidant defence mechanisms. However, such an increase within tumour cells strengthens the mechanisms of tumour progression and invasion, and prevents cell death. Our specific objectives in this line of research are as follows:

  • Describe the role of mitochondria and mitochondrial antioxidant proteins in tumour progression.
  • Determine the role of the TXNIP protein (TRX-interacting protein) as a bridge between glycolytic metabolism and redox balance in cancer.
  • Seek new biomarkers based on the redox changes that take place in tumour cells.
3 - The Participation of Circadian Redox Oscillations in Pathological Processes

Night work has been defined as a possible carcinogen. Our research group has spent over 20 years working on the biological properties of the pineal neuroindole melatonin which, as well as mediating the cycles of light and darkness, is a powerful endogenous antioxidant. Our specific objectives in this line of research are to:

  • Demonstrate the importance of melatonin throughout evolution as a modulator of the basic mechanisms of cell survival.
  • Investigate whether there is any redox control of the genetic machinery that regulates the circadian rhythm.
  • Determine the role of selenoproteins which participate in redox control and undergo non-transcriptional circadian changes in cancer.
4 - The Development of Analytical Methods Based on Isotope Dilution Analysis for the Absolute Quantification of Biomarkers in Cancer

The use of certain biomarkers has been seriously called into question in recent years. Some are non-specific markers, and as such have certain limitations. In other cases, biomarker levels may be affected by several factors that are not necessarily related to tumour growth. The specific objectives of our group in this line of research are to develop:

  • Exact and precise analytical methods for the determination of proteins and their subsequent utility as biomarkers.
  • Non-invasive methods for the determination of metabolic parameters that enable us to predict the probability of cancer recurrence.
