Genomic analysis of APP, PSEN1 and MAPT genes involved in the pathogenesis of Alzheimer’s disease

Neurodegenerative diseases, such as Alzheimer’s disease or other forms of dementia, represent a major challenge for global public health, and understanding the genetic mechanisms involved is essential for the development of diagnostic and treatment strategies. This work aims to study three key genes involved in the pathogenesis of neurodegeneration: APP (Amyloid Precursor Protein), PSEN1 (Presenilin 1) and MAPT (Microtubule Associated Protein Tau). The aim of the research is to analyze the classification of these genes, pathogenic genetic variations and frequent polymorphisms, as well as their impact on physiological and pathological processes. The methodology is based on a comparative analysis of data from the specialized literature and from genetic and expression databases, including GTEx, Human Protein Atlas, STRING and GeneMANIA platforms, as well as integrations from genome-wide association studies (GWAS).

The Evolution of Global Warming: Tipping Points, Human Inaction, and Future Scenarios

Global warming is an unequivocal reality, and overwhelming scientific evidence attributes this rapid climate change to human activities. Since the Industrial Revolution, humans have poured billions of tons of carbon dioxide (CO₂) and other greenhouse gases into the atmosphere, trapping heat and raising Earth’s temperature at an unprecedented rate. The scientific consensus is clear: human-induced climate change is real, measurable, and accelerating, and its potential consequences pose profound challenges for the future of civilization. On one path, humanity manages to unite in an unprecedented effort to cut emissions, protect ecosystems, and innovate towards sustainability – in time to avert the worst outcomes. On the other, we continue with half-hearted measures and discord, thereby forfeiting our last chance to keep climate change within controllable bounds.
