Neural Regulation01:37

Neural Regulation

44.2K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Parkinson's Disease: Overview

2.3K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Parkinson's Disease: Treatment

1.3K
Neurodegenerative disorders, such as Parkinson's Disease (PD), involve the gradual and irreversible destruction of neurons in particular brain areas. These disorders exhibit standard features like proteinopathies, selective vulnerability of some neurons, and an interaction of intrinsic properties, genetics, and environmental influences in neural injury.
Parkinson's Disease is primarily a result of the loss of dopaminergic neurons in the substantia nigra pars compacta. The cornerstone of...

Human Genetics

1.8K
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

EPS and iPS Cells in Disease Research

3.5K
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

Epigenetic Regulation01:37

Epigenetic Regulation

4.1K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

    Area of Science:

    • Genetics and Epigenetics
    • Molecular Biology
    • Developmental Biology

    Background:

    • Genetic information is encoded in DNA, acting as an organism's blueprint.
    • Epigenetic modifications, including DNA methylation and histone modifications, regulate gene transcription.
    • These modifications are crucial for cell differentiation, development, and functions like learning and memory.

    Purpose of the Study:

    • To highlight the role of epigenetic modifications in gene regulation.
    • To explain how environmental factors influence epigenetic patterns.
    • To discuss the implications of epigenetics in health, disease, and drug responses.

    Main Methods:

    • The abstract does not specify methods but discusses established concepts in epigenetics.
    • It reviews the known mechanisms of DNA methylation and histone modifications.
    • It synthesizes information on the environmental and disease-related impacts of epigenetics.

    Main Results:

    • Epigenetic modifications determine cell-specific gene expression patterns.
    • Environmental conditions can alter DNA methylation patterns, with potential heritability.
    • Epigenetic alterations are implicated in various diseases, including neuro-psychiatric disorders.

    Conclusions:

    • Epigenetic modifications are key regulators of gene function and cellular identity.
    • DNA methylation mediates the impact of environmental factors on health and disease.
    • Epigenetics plays a role in both classical genetic disorders and sporadic neuro-psychiatric conditions.
