We have reported that the sequence variation in the tenomodulin (TNMD) gene is associated with the risk of type 2 diabetes (T2DM), central obesity and serum levels of systemic immune mediators in the Finnish Diabetes Prevention Study (DPS), which is a longitudinal lifestyle intervention study on 522 middle-aged persons with impaired glucose tolerance (IGT). The aim of this study was to investigate whether the association with T2DM, observed in the DPS could be replicated in a larger, cross-sectional population-based random sample of 5298 men (3020 with normoglycaemia, 984 with impaired fasting glucose, 436 with IGT and 811 with T2DM) from the region of Kuopio, eastern Finland. To further explore the putative mechanisms linking TNMD to T2DM and metabolic syndrome, we studied the associations of TNMD sequence variation with lipid abnormalities characteristic to metabolic syndrome. The association with T2DM risk was not replicated, but significant associations were found with serum low-density lipoprotein and total cholesterol in a body mass index-dependent manner. These associations were also observed in the men of DPS, whereas in women these associations were not significant. These results from two independent study populations suggest that the genetic variation in TNMD could modulate cholesterol metabolism in obese men.

The current nutritional habits and lifestyles of modern societies favor energy overloads and a diminished physical activity, which may produce serious clinical disturbances and excessive weight gain. In order to investigate the mechanisms by which the environmental factors interact with molecular mechanisms in obesity, a pathway analysis was performed to identify genes differentially expressed in subcutaneous abdominal adipose tissue (SCAAT) from obese compared to lean male (21-35 year-old) subjects living in similar obesogenic conditions: habitual high fat dietary intake and moderate physical activity. Genes involved in inflammation (ALCAM, CTSB, C1S, YKL-40, MIF, SAA2), extracellular matrix remodeling (MMP9, PALLD), angiogenesis (EGFL6, leptin) and oxidative stress (AKR1C3, UCHL1, HSPB7 and NQO1) were upregulated; whereas apoptosis, signal transcription (CITED 2 and NR3C1), cell control and cell cycle-related genes were downregulated. Interestingly, the expression of some of these genes (C1S, SAA2, ALCAM, CTSB, YKL-40 and tenomodulin) was found to be associated with some relevant metabolic syndrome features. The obese group showed a general upregulation in the expression of inflammatory, oxidative stress, extracellular remodeling and angiogenic genes compared to lean subjects, suggesting that a given genetic background in an obesogenic environment could underlie the resistance to gaining weight and obesity-associated manifestations.

Tenomodulin (TNMD) is a type II transmembrane glycoprotein that has been recently linked to obesity, and it is highly expressed in obese adipose tissue. Several sex-dependent associations have been observed between single-nucleotide polymorphisms (SNPs) of the TNMD gene, which is located in the X-chromosome, and obesity, type 2 diabetes mellitus (T2DM), and metabolic syndrome in adults. On the other hand, results are lacking for children. We aimed (i) to study the association between TNMD genetic variants and metabolic complications related to childhood obesity and (ii) to investigate the function of TNMD in human adipocytes. We conducted a case-control, multicenter study in 915 Spanish children and demonstrated significant positive associations between TNMD genetic variants and BMI z-score, waist circumference, fasting glucose, and insulin resistance in boys, highlighting the SNP rs4828038. Additionally, we showed a BMI-adjusted inverse association with waist circumference in girls. Second, in vitro experiments revealed that TNMD is involved in adipogenesis, along with glucose and lipid metabolism in differentiated adipocytes, and these effects may be mediated through AMPK activation. Hence, these results suggest that TNMD genetic variants could be potentially useful as early life risk indicators for obesity and T2DM. In addition, we support the fact that TNMD exhibits significant metabolic functions in adipocytes.
