Regulation of Gene Expression and Its Role in Development and Disease: A Case of India

Rachel Amaira — 2024-04-22

Purpose: The aim of the study was to investigate the Regulation of Gene Expression and Its Role in Development and Disease: A Case of India.

Findings: The study revealed that regulation of gene expression plays a fundamental role in orchestrating the intricate processes of development and maintaining cellular homeostasis in health and disease. Through a myriad of molecular mechanisms, including epigenetic modifications, transcriptional regulation, and non-coding RNA activity, cells finely tune gene expression patterns to drive differentiation, tissue-specific functions, and response to environmental cues. Transcriptional regulatory networks govern the activation or repression of gene expression programs critical for organogenesis, tissue regeneration, and immune responses. Dysregulation of these networks, often involving aberrant transcription factor activity or disrupted signaling pathways, can lead to developmental abnormalities, cardiovascular diseases, and immune-related disorders.

Unique Contribution to Theory, Practice and Policy: Central dogma of molecular biology & gene regulatory network theory may be used to anchor future studies on regulation of gene expression and its role in development and disease. Utilize molecular profiling technologies to stratify patients based on their gene expression profiles, enabling personalized diagnosis, prognosis, and treatment selection tailored to individual molecular signatures. Identify novel therapeutic targets by targeting dysregulated gene expression pathways in disease. Implement policies to promote data sharing and collaboration across research institutions and international consortia. Develop ethical guidelines for the use of gene expression data in research and clinical settings. Ensure responsible data stewardship, patient privacy protection, and equitable access to emerging technologies to prevent misuse and address societal concerns surrounding genomic information.

Role of Non-Coding RNAs in Gene Regulation in Brazil

Joyce Laula — 2024-04-22

Purpose: The aim of the study was to examine the role of non-coding RNAs in gene regulation in Brazil

Findings: The study found that non-coding RNAs (ncRNAs) play diverse and pivotal roles in gene regulation across various biological processes. From microRNAs (miRNAs) and long non-coding RNAs (lncRNAs) to circular RNAs (circRNAs) and transfer RNA-derived fragments (tRFs), ncRNAs participate in fine-tuning gene expression at multiple levels, including transcriptional and post-transcriptional regulation. These molecules act as crucial regulators of cellular homeostasis, development and disease pathogenesis.

Unique Contribution to Theory, Practice and Policy: Central dogma of molecular biology & competitive endogenous rna (cerna) hypothesis may be used to anchor future studies on role of non-coding RNAs in gene regulation in Brazil. Leveraging the dysregulated expression of non-coding RNAs as diagnostic and prognostic biomarkers will facilitate the development of personalized therapeutic strategies. By targeting specific non-coding RNAs associated with disease states, clinicians can tailor treatment regimens to individual patients, improving efficacy and minimizing adverse effects. Policymakers should prioritize funding for non-coding RNA research, recognizing its significance in advancing biomedical knowledge and improving healthcare outcomes. Educational institutions and professional organizations should incorporate non-coding RNA biology into undergraduate and graduate curricula, as well as continuing education programs for healthcare professionals.
