ADAMTS14 gene polymorphism associated with knee osteoarthritis in Thai women

T. Poonpet, Honsawek, S., Tammachote, N., Kanitnate, S., and Tammachote, R., ADAMTS14 gene polymorphism associated with knee osteoarthritis in Thai women, vol. 12, pp. 5301-5309, 2013.

Osteoarthritis (OA) is the most prevalent form of arthritis in the elderly. This disease is characterized by breakdown and loss of articular cartilage due to genetic, mechanical and environmental factors. Although the pathophysiology of OA is not completely known, several candidate genes have been reported to be associated with OA susceptibility. We assessed the association between genetic variation in the ADAMTS14 region and knee osteoarthritis susceptibility in the Thai population.

Association between the -1438A/G polymorphism of the serotonin 2A receptor gene and late-onset psoriasis in a Thai population

C. Ronpirin, Tencomnao, T., and Wongpiyabovorn, J., Association between the -1438A/G polymorphism of the serotonin 2A receptor gene and late-onset psoriasis in a Thai population, vol. 9, pp. 208-214, 2010.

Expression of serotonin 2A receptor (5-HTR2A) is known to increase in psoriasis, a chronic inflammatory skin disease. We investigated a possible association between the -1438A/G single nucleotide polymorphism (rs6311) in the promoter region of 5-HTR2A gene and psoriasis in a Thai population. One hundred and twelve psoriatic patients and 151 unrelated healthy controls were included in our study. Genotyping was performed using the polymerase chain reaction and restriction fragment length polymorphism techniques.

Association of C/T polymorphism in intron 14 of the dopamine transporter gene (rs40184) with major depression in a northeastern Thai population

N. Pattarachotanant, Sritharathikhun, T., Suttirat, S., and Tencomnao, T., Association of C/T polymorphism in intron 14 of the dopamine transporter gene (rs40184) with major depression in a northeastern Thai population, vol. 9, pp. 565-572, 2010.

Several lines of evidence suggest that the dopaminergic system is involved in the pathophysiology of major depressive disorder (MDD). Since the dopamine transporter (DAT1, also known as SLC6A3), mediates the active reuptake of dopamine from the synapses and thereby plays a vital role in the regulation of dopaminergic neurotransmission, we looked for a possible association between the C/T single nucleotide polymorphism in intron 14 of the DAT1 gene (also referred to as rs40184) and MDD in a northeastern Thai population.

No relationship found between -1438A/G polymorphism of the serotonin 2A receptor gene (rs6311) and major depression susceptibility in a northeastern Thai population

T. Tencomnao, Thongrakard, V., Phuchana, W., Sritharathikhun, T., and Suttirat, S., No relationship found between -1438A/G polymorphism of the serotonin 2A receptor gene (rs6311) and major depression susceptibility in a northeastern Thai population, vol. 9, pp. 1171-1176, 2010.

Several lines of evidence suggest a molecular role of -1438A/G single nucleotide polymorphism in the 5-HTR2A gene promoter (rs6311) in regulating the expression of this gene, making rs6311 polymorphism a promising candidate for an association study. We looked for a possible association between rs6311 polymorphism and major depressive disorder (MDD) in a northeastern Thai population. We included 180 patients with MDD and 183 unrelated healthy controls in our study. Genotyping was performed using PCR-RFLP.

An investigation of the relationship between serotonin transporter gene promoter polymorphism and psoriasis susceptibility in a Thai population

T. Tencomnao and Wongpiyabovorn, J., An investigation of the relationship between serotonin transporter gene promoter polymorphism and psoriasis susceptibility in a Thai population, vol. 9, pp. 2275-2282, 2010.

The serotonin transporter (5-HTT) is of great significance in the control of the serotonergic system, and its expression is known to be upregulated in psoriasis, a chronic or recurrent inflammatory skin disease. We investigated a possible association between the 5-HTT gene-linked polymorphic region (5-HTTLPR) and psoriasis in a Thai population. One hundred and fifty-six psoriatic patients and 156 unrelated healthy controls from Bangkok were genotyped using PCR. We found no overall differences in genotype distributions or allele frequencies between the two groups.
