Brain Imaging

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Disorders of the Nervous Tissue

Disorders of the Nervous Tissue

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
Homeostatic Imbalances:
Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.
Parkinson's disease arises from the...

Background:

TP53 and RB1 gene mutations are implicated in malignant brain tumor development.
Recent findings suggest LGI1 mutations are involved in brain tumor progression.

Purpose of the Study:

To sequence TP53, RB1, and LGI1 genes in high- and low-grade gliomas.
To classify identified mutations as 'driver' or 'passenger' to understand their role in brain cancer.

Main Methods:

DNA sequencing of glioma samples and matched normal DNA.
Bioinformatic analysis to identify and classify gene mutations.

Main Results:

Identified 35 unique missense mutations across TP53, RB1, and LGI1 genes.
Classified mutations based on their potential to drive cancer development.
Found putatively deleterious mutations in the LGI1 gene.

Conclusions:

The study identifies novel mutations in key genes associated with gliomas.
Findings support a potential role for LGI1 in the development of brain cancers.
Distinguishing driver from passenger mutations is crucial for understanding brain tumor etiology.
