Increased Serum Interleukin-2 Levels Are Associated with Abnormal Peripheral Blood Natural Killer Cell Levels in Patients with A
amm1812

In rheumatoid Arthritis patients, NK cell levels were abnormally elevated, possibly due to high serum levels of IL-2.

Rheumatoid arthritis (RA), is an autoimmune disease that means our own immune system attacks self healthy cells in the body by mistake, causing inflammation (painful swelling),mainly attacks the joints.

The given study is to investigate the relationship between serum interleukin-2 (IL-2) levels and disease activity.

This study also showed the relationship between absolute numbers of peripheral lymphocyte subsets, autoantibodies, and associated cytokines in patients with rheumatoid arthritis (RA).

The results showed that the number and percentage of NK cells were positively correlated with serum IL-2 levels so, IL-2 can be a reason for elevated level of NK cells

Explain how a mutation near, but outside of, the coding region of Pitx1 may cause a loss of pelvic fins without pleiotropic effe
ipn [44]

Since the Pitx1 gene codes for a protein crucial im lower limns development, a mutation occurring near Pitx1 gene will affect refikjs around the lower limbs but not those far away from it.

<h3>What are mutations?</h3>

Mutations refers to alterations or error that occur which change the original sequence of nucleotides in a DNA molecule.

The Pitx1 gene is a gene that codes for a protein that involved in development of the lower limbs.

A mutation near but outside of the coding region of Pitx1 may cause a loss of pelvic fins without pleiotropic effects on the pituitary gland and jaw because the pelvic fins form part of the lower limbs whole the jaws and the pituitary gland are not found in the lower limbs.

Therefore, the mutation occurring near Pitx1 gene will affect regions around the lower limbs but not those far away from it.

Is race a biological characteristic determined by our genes?
Harman [31]

Answer:

No, they are not. The concept of human races appears to be solidly grounded in present-day biology and our evolutionary history. But if you asked that conference of geneticists to give you a genetic definition of race, they wouldn’t be able to do it. Human races are not natural genetic groups; they are socially constructed categories. Genes certainly reflect geography, but unlike geography, human genetic differences don't fall along obvious natural boundaries that might define races.
