Changes in Metabolic Parameters in Patients with Diabetic Kidney Disease Depending on the Status of D3

BACKGROUND

Type 2 diabetes is a metabolic disease characterized by hyperglycemia as a result of insulin resistance and decreased insulin secretion. A relatively large number of patients with this type of diabetes have abdominal obesity, which also affects insulin resistance development. Chronic hyperglycemia can lead to damage and dysfunction of various organs, and a striking example is diabetic nephropathy. Diabetic nephropathy is a specific kind of kidney damage that occurs due to complications of diabetes and is accompanied by the formation of diffuse or nodular glomerulosclerosis, which can lead to terminal renal failure and requires immediate substitution through renal therapy or renal transplantation. Diabetic nephropathy is diagnosed with albuminuria and a decrease in the rate of glomerular filtration.

METHODS

This review was based on a literature search for the most important evidence of vitamin D as a possible method of prevention for obesity, type 2 diabetes, and diabetic nephropathy. Collected published articles were summarized according to their overall themes.

RESULTS

In this review, we considered vitamin D as a possible method of treatment for type 2 diabetes, as well as its complications, including diabetic nephropathy.

CONCLUSION

Studies show that vitamin D inhibits the renin-angiotensin-aldosterone system, resulting in improved renal function in diabetic nephropathy. Vitamin D also has antiinflammatory, antiproliferative, and anti-metastatic effects, which improve endothelial function.

Tetrahymena macronuclear genome mapping: colinearity Of macronuclear coassortment groups and the micronuclear map on chromosome 1l

The genetics of the ciliate Tetrahymena thermophila are richer than for most other eukaryotic cells, because Tetrahymena possesses two genomes: a germline (micronuclear) genome that follows a Mendelian model of genetic transmission and a somatic (macronuclear) genome, derived from the micronuclear genome by fragmentation, which follows a different genetic transmission model called phenotypic assortment. While genetic markers in the micronucleus fall into classical linkage groups under meiotic recombination and segregation, the same markers in the macronucleus fall into coassortment groups (CAGs) under phenotypic assortment by the random distribution of MAC chromosome pieces. We set out to determine whether genomic mapping in the macronucleus by genetic means is feasible. To investigate the relationship between the micronuclear map and coassortment groups, we systematically placed into CAGs all of the markers lying on chromosome 1L that are also found in the macronucleus. Sixteen CAGs were identified, 7 of which contain at least two loci. We have concluded that CAGs represent a fundamental genetic feature of the MAC. The MIC and MAC maps on 1L are colinear; that is, CAGs consist exclusively of markers that map to a continuous segment in a given region of the micronuclear map, with no intervening markers from other CAGs. These findings provide a solid foundation for exploiting the MAC chromosome pieces to build a physical map of the Tetrahymena genome.
