- Ensuring Sample Integrity: Using methods that prevent RNA degradation and ensure the stability of genetic material for accurate analysis.
- Performing Gene Expression Analysis:
- Extracting RNA: Isolating RNA from collected samples using reliable extraction methods.
- Conducting RNA Sequencing or RT-PCR: Utilizing quantitative real-time PCR or next-generation sequencing technologies to assess the expression levels of genes related to antioxidative pathways.
- Analyzing and Interpreting Data:
- Processing Data: Employing bioinformatics tools to analyze gene expression data, identifying significant changes and patterns.
- Correlating Gene Expression with Antioxidant Intake: Linking changes in gene expression to antioxidant consumption levels and evaluating the biological implications of these changes.
- Reporting and Sharing Findings:
- Writing Detailed Reports: Documenting methodologies, results, and conclusions in comprehensive reports or scientific papers, ensuring reproducibility and transparency.
- Publishing Findings: Submitting results to peer-reviewed journals and presenting findings at conferences to contribute to the broader understanding of how dietary antioxidants influence gene expression.
Time Duration: 3 Months.
When Implemented: Implemented in research that examines the role of dietary antioxidants in preventing oxidative damage and promoting longevity.
Importance of the Protocol: Understanding the impact of dietary antioxidants on gene expression is vital for developing nutritional strategies that mitigate oxidative stress and promote healthy aging. This protocol aids in identifying how natural food components can support cellular health and prevent age-related diseases, making it a cornerstone in nutrition research aimed at extending healthy lifespans.

I have completed my 6 month dissertation in NTHRYS biotech labs. The lab is adequately equipped with wonderful, attentive and receptive staff. It is a boon to the students venturing into research as well as to students who would like to garner lab exposure. I had a pleasant experience at NTHRYS thanks to Balaji S. Rao Sir for his constant support, mettle and knowledge. I would also like to give special regards to Zarin Mam for teaching me the concepts of bioinformatics with great ease and for helping me in every step of the way. I extend my gratitude to Vijaya Mam, and Sindhu Mam for helping me carry out the project smoothly.

I’m a biotechnology student from Dy patil University mumbai and I recently completed my 6 months dissertation project at Nthrys Biotech Labs in Hyderabad. I had a great experience and I would highly recommend this lab to other students as well .
The first thing that I appreciated about Nthrys Biotech Labs was the friendly and supportive environment. Balaji sir and the staff Ragini and Sandhya ma’am were always willing to help me and they were always patient with my questions.
I also felt like I was part of a team and that I was making a real contribution to the companys research.
I learned a lot during my dissertation at Nthrys Biotech Labs not only academically but also personally . I had the opportunity to work on a variety of projects, which gave me a broad exposure to the field of biotechnology. I also learned a lot about the research process and how to conduct experiments.
In addition to the technical skills that I learned, I also developed my soft skills during my internship. I learned how to communicate effectively, how to work independently, and how to work as part of a team.
Overall, I had a great experience at Nthrys Biotech Labs and I would highly recommend this company to other students.
Once again I would like to render a big thank you to Balaji Sir and Vijayalakshmi ma’am for imbibing with all the knowledge along with helping me publish my research paper as well and its all because of them I scored unbelievably well in my final semester.
