Neural Regulation01:37

Neural Regulation

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.
Functions of the Nervous System01:18

Functions of the Nervous System

The nervous system is responsible for coordinating and regulating the body's functions. It functions through three main processes: sensory, integrative, and motor processes. Sensory function involves the detection and transmission of information about internal and external stimuli from sensory receptors to the CNS. The CNS processes this information through an integrative function, where it interprets and makes decisions based on the incoming sensory information. Finally, the motor function...
Major Somatic Sensory Pathways01:28

Major Somatic Sensory Pathways

Sensory impulses related to touch, pressure, vibration, and proprioception from various body parts, such as the limbs, trunk, neck, and posterior head, travel to the cerebral cortex through the posterior column-medial lemniscus pathway. The pathway’s name derives from the two white-matter tracts that convey the impulses: the spinal cord's posterior column and the brainstem's medial lemniscus. First-order sensory neurons extend their axons into the spinal cord, forming the posterior columns...
Global Regulatory Systems01:28

Global Regulatory Systems

Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...
Drug Control Governance: Regulatory Bodies and Their Impact01:03

Drug Control Governance: Regulatory Bodies and Their Impact

Drug control governance involves the oversight and regulation of pharmaceuticals to ensure their safety and efficacy while preventing illegal drug use and trafficking. Regulatory bodies, including the US Food and Drug Administration (FDA) and the European Union's European Medicines Agency (EMA), play a central role in this process. These agencies evaluate the safety and efficacy of drugs before they can be marketed. They fund clinical trials and assess the benefits and risks associated with a...
Psychosurgery01:30

Psychosurgery

Psychosurgery, the surgical alteration or permanent removal of brain tissue to alleviate severe psychological conditions, stands as one of the most radical and controversial treatments in the history of mental health care. Its development and application have evolved significantly, marked by dramatic shifts in scientific understanding and ethical perspectives.
Historical Development of Psychosurgery
In the 1930s, Portuguese neurologist Antonio Egas Moniz introduced a surgical procedure designed...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cell Biology

Background:

  • Posttranslational modification by small ubiquitin-like modifier (SUMO) regulates critical cellular processes.
  • Protein sumoylation is increasingly linked to diseases including heart failure, cancer, and neurodegeneration.
  • Mechanisms connecting SUMO modification to disease pathogenesis remain largely unknown.

Purpose of the Study:

  • To critically review current concepts of the SUMO pathway.
  • To highlight differential SUMO regulation in healthy versus diseased states, with a focus on neurologic aspects.
  • To provide insights for uncovering pathogenic mechanisms and developing disease-specific therapies.

Main Methods:

  • Literature review of existing research on SUMOylation.
  • Analysis of SUMO pathway regulation in various cellular events.
  • Focus on comparative analysis between healthy and diseased states, particularly in neurological contexts.

Main Results:

  • SUMOylation impacts diverse cellular functions such as transcription, DNA repair, and nuclear transport.
  • Dysregulation of SUMOylation is observed in major diseases.
  • Specific mechanisms of SUMO's role in disease are still under investigation.

Conclusions:

  • A deeper understanding of SUMO pathway regulation in health and disease is necessary.
  • Investigating differential SUMOylation may reveal disease mechanisms.
