Background: The folate metabolism pathway plays an integral part in DNA synthesis, methylation, and repair. Methylenetetrahydrofolate reductase (MTHFR) and methylenetetrahydrofolate dehydrogenase (MTHFD1) are both enzymes that are involved in this pathway, and the single nucleotide polymorphisms (SNPs) in genes coding for them have modulatory effects on DNA expression. This study aimed to investigate the relationship between MTHFR C677T (rs1801133) and MTHFD1 G1958A (rs2236225) polymorphisms and the risk of developing breast cancer in Georgian women.

It exhibits various inheritance patterns involving pathogenic variants in , , and genes. The phenotypes can range from isolated hematuria with a non-progressive or very slowly progressive course to progressive kidney disease with extrarenal abnormalities.

It is involved in two of the hallmarks of cancer: vascularization and immune modulation. IL-10 inhibits angiogenesis and hence is antitumorigenic.

It is caused by heterozygous loss-of-function pathogenic variants in the gene, which codes for an ankyrin repeat-containing protein. Currently, about 35 cases of Chopra-Amiel-Gordon syndrome are described in the medical literature.

It is caused by mutations in the cystic fibrosis transmembrane conductance regulator gene, which encodes a chloride ion channel expressed on the surface of epithelial cells. There are more than 2000 variants of the cystic fibrosis transmembrane conductance regulator gene reported worldwide.

The disorder is caused by missense variants in the MSMO1 gene encoding methylsterol monooxygenase 1, leading to the accumulation of methylsterols. Clinically, MSMO1 deficiency is characterized by growth and developmental delay, often in association with congenital cataracts, microcephaly, psoriasiform dermatitis and immune dysfunction.

More than 200 cases are reported in the literature. Major clinical findings include short stature, developmental delay, intellectual disability, and characteristic facial dysmorphic features.

Methods: This case-control study recruited patients with migraine without aura and age-matched healthy control subjects. PBMCs were purified from peripheral blood samples.

Nager syndrome (MIM #154400) is a rare acrofacial dysostosis syndrome predominantly characterized by malformations in craniofacial and preaxial limb bones. Most cases are sporadic and present with significant clinical heterogeneity. Although autosomal recessive and autosomal dominant modes of inheritance have been reported, most cases of Nager syndrome are spontaneous.

Interestingly, the sibling with I1234V and L997F variants had normal sweat test results and had a much milder phenotype than the other two siblings with I1234V and 1677delTA variants, suggesting that this combination is causative for atypical CF. The fact that their mother with the combination of 1677delTA and L997F appears to be healthy suggests that the L997F variant causes different phenotypes in different allele combinations.

All these factors have been shown to cause epigenetic modifications via DNA hypomethylation, thus forming a basis for cancer development. Several published reviews and studies were systematically reviewed.

Thirty-four patients and 29 healthy individuals were recruited in this study. Polymerase chain reaction-restriction fragment length polymorphism analyses were used for genotyping of polymorphisms.

Given this evidence, in this study we investigated the development of tolerance to the analgesic effects of NSAIDs diclofenac, ketorolac and xefocam microinjected into the rostral part of anterior cingulate cortex (ACC) in rats.
Methods: Male Wistar experimental and control (saline) rats were implanted with a guide cannula in the ACC and tested for antinociception following microinjection of NSAIDs into the ACC in the tail-flick (TF) and hot plate (HP) tests.
TRPA1 agonists cinnamaldehyde (CA) and mustard oil (allyl isothiocyanate=AITC) induce heat hyperalgesia and mechanical allodynia in human skin, and sensitize responses of spinal and trigeminal dorsal horn neurons to noxious skin heating in rats. TRPA1 is also implicated in cold nociception. We presently used behavioral methods to investigate if CA affects sensitivity to thermal and mechanical stimuli in rats.
