- In a videoconference given by Dra. Elizabeth Reyna Beltrán
Tampico, Tam. In the framework of the dissemination of science and research promoted by the Autonomous University of Tamaulipas (UAT), the Faculty of Medicine of Tampico “Dr. Alberto Romo Cavaller” disseminates by digital means the work of Dr. Elizabeth Reyna Beltrán, professor and researcher at this faculty.
Through the YouTube platform, an explanatory video made within the University Integral Training Program is made known, in which the scientific trajectory of Dra. Beltrán, the emergence of his interest in science, the lines of research in which he is working, the importance of research in the medical area and recommendations for joining or starting a research project.
The university researcher details her experience gained through the research stay, where she narrates that when working with salmonella species to find out how certain specific genes are transmitted, she decides to venture into scientific research.
Thus, as a project of his mastery, he worked with a study model of Candida albicans, The main pathogenic fungus in humans.
“My main goal was to identify which enzyme, specifically, made covalent bonds between proteins. This function is essential in the case of the cell wall of this fungus, as it is the first structure that interacts with cells. and allows the fungus to be resistant to adverse environmental conditions, such as oxidizing agents, drugs, desiccation, among others. ”
After presenting the results at several national conferences, he continued this project during his doctorate, and specifically identified the enzyme that was forming the covalent bonds in the cell wall.
“And precisely at this stage of the doctorate we find that it is a transglutaminase, and that it is essential for the biology of the fungus, since by inhibiting its enzymatic activity there was no formation of mycelium of C. albicans, Which are very important because they are involved in the formation of large mycelial structures inside the tissues, ie to invade the tissues of patients.
He stressed that he is currently continuing to collaborate on pathogen-related topics, through a project for the implementation of silver nanoparticles as microbicidal agents of bacteria that are resistant to highly used drugs.
Finally, Dra. Elizabeth Reyna Beltrán points out the importance of instilling in students an interest in scientific research:
“If as a student you have an interest in doing scientific research related to the medical area, and thus contribute to the identification of a new drug, in the identification of a protein involved in a disease, in knowing how they are carry out the different cellular processes, you can always turn to the research professors of the faculty, and even to other specialists of the university, so that you find the area or specialty in which you would like to focus “.
