Tumor Progression

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

mTOR Signaling and Cancer Progression

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Multiple Regression

Multiple Regression

Multiple regression assesses a linear relationship between one response or dependent variable and two or more independent variables. It has many practical applications.
Farmers can use multiple regression to determine the crop yield based on more than one factor, such as water availability, fertilizer, soil properties, etc. Here, the crop yield is the response or dependent variable as it depends on the other independent variables. The analysis requires the construction of a scatter plot...

Types of Genetic Transfer Between Organisms

Types of Genetic Transfer Between Organisms

Genetic transfer occurs when genetic information is passed from one organism to another. It occurs via two mechanisms: vertical gene transfer and horizontal gene transfer. Vertical gene transfer occurs when genetic information is transferred from one generation to the next, which happens much more frequently than horizontal gene transfer. Both sexual and asexual reproduction are forms of vertical gene transfer, where one or more organisms pass some or all of their genome onto their progeny.

Deformation of Member under Multiple Loadings

Deformation of Member under Multiple Loadings

When a rod is made of different materials or has various cross-sections, it must be divided into parts that meet the necessary conditions for determining the deformation. These parts are each characterized by their internal force, cross-sectional area, length, and modulus of elasticity. These parameters are then used to compute the deformation of the entire rod.
In the case of a member with a variable cross-section, the strain is not constant but depends on the position. The deformation of an...

Area of Science:

Neurogenetics
Neurology
Demyelinating diseases

Background:

Multiple sclerosis (MS) is a central nervous system inflammatory demyelinating disease.
Neurofibromatosis type 1 (NF1) is an autosomal dominant disorder affecting the nervous system.
The co-occurrence of MS and NF1 is exceptionally rare.

Observation:

A patient with primary progressive MS (PPMS) and NF1 was analyzed.
Whole exome sequencing and Sanger sequencing were employed.
The study focused on identifying genetic factors contributing to the dual diagnosis.

Findings:

A novel de novo deletion (c.6817delC) and an rs1801052 polymorphism in the NF1 gene were identified.
These genetic variations are associated with NF1 symptoms.
Multiple polymorphisms in SPG7, SPG15, and SPG39 genes linked to benign spastic paraplegia were also observed.

Implications:

Genetic alterations may underlie the co-occurrence of PPMS and NF1.
This case provides insights into the genetic basis of complex neurological presentations.
Further research into genotype-phenotype correlations in rare neurological comorbidities is warranted.
