Abstract Background Apelin, as an adipokine, plays an important role in the pathogenesis of insulin resistance and type 2 diabetes. This study aimed to determine whether the quality and quantity of dietary carbohydrates were associated with apelin gene expression in subcutaneous and visceral adipose tissues. Methods In this cross-sectional study, 102 adults who underwent minor abdominal surgery were selected. Approximately 100 mg of subcutaneous and visceral adipose tissues were collected during the surgery to measure apelin gene expression. Anthropometric measurment, blood samples, and dietary intakes were collected before surgery. The dietary carbohydrate intake, glycemic index (GI), and glycemic load (GL) were determined. Results The average apelin concentration was 269.6 ± 98.5(pg/mL), and 16.3% of participants were insulin resistant. There was a correlation between insulin (p-value = 0.043), Homeostatic Model Assessment for Insulin Resistance (HOMA-IR)(p-value = 0.045) and apelin gene expression in visceral adipose tissue. There was a positive association of apelin gene expression with dietary GI and GL after adjustment for age, sex, and waist circumference in visceral and subcutaneous adipose tissues(p < 0.05). Apelin gene expression in visceral(p = 0.002) and subcutaneous(p = 0.003) adipose tissues was directly associated with foods with a higher GI. There was no association between total carbohydrate intake and apelin gene expression in both visceral and subcutaneous adipose tissues. Conclusions Dietary GI and GL, not total carbohydrate intake, were positively associated with apelin gene expression in both visceral and subcutaneous adipose tissues. Future studies are warranted to illustrate the chronic and acute effect of carbohydrate quality on apelin homeostasis.

Abstract This study investigated effects of dietary glycerol supplementation on liver, muscle, and adipose gene expression related with gluconeogenesis and lipid metabolism and association of gene expression levels with marbling score in Korean cattle steers. Fourteen Korean cattle steers (average age 28.4 months; average body weight 733 kg) were equally assigned to two groups (0 and 5% glycerol supplementation). Glycerol was provided with glycerol (63%)-adsorbed ground wheat bran (37%, DM) by top dressing during roughage feeding. A concentrate (1.2% of body weight) and 1.0 kg of ryegrass were individually fed twice daily. After four months of study, steers were slaughtered, and marbling score was evaluated. Longissimus thoracis (LT) and subcutaneous adipose tissue at the 13th thoracic vertebra area and liver were collected and analyzed for mRNA levels by quantitative real-time PCR. Statistical significance was analyzed by analysis of variance. Correlations were analyzed using Pearson’s correlation analysis. Glycerol supplementation increased (P = 0.01) marbling score. In the LT, glycerol supplementation tended to increase (0.05 &lt; P ≤ 0.10) lipid uptake CD36 and lipoprotein lipase (LPL) mRNA levels. In subcutaneous adipose tissues, glycerol supplementation increased (P ≤ 0.05) LPL, adipogenic sterol regulatory element binding protein 1 (SREBP1), and lipogenic acetyl CoA carboxylase (ACC) mRNA levels and tended to increase (0.05 &lt; P &lt; 0.10) CD36, adipogenic peroxisome proliferator-activated gamma (PPARG), and lipogenic fatty acid synthase (FASN) expression. It did not affect (P &gt; 0.05) mRNA levels of hepatic gluconeogenesis genes. Marbling score showed significant positive correlations (0.57 &lt; r &lt; 0.68; P &lt; 0.05) with mRNA levels of several genes including LPL, PPARG, SREBP1, and ACC in adipose tissues, but not with any genes examined in the LT. Our study demonstrates that lipid uptake, adipogenesis and lipogenesis may mainly contribute to the increased marbling score by glycerol supplementation.

Background: Obesity is a pathological condition that has reached epidemic proportions; hence, it is necessary to find novel strategies aimed at fighting this disease. The present study was designed to evaluate the effect of a flavonoid-rich extract of orange (Citrus sinensis) juice (OJe) in diet-induced obese zebrafish. Methods: Adult zebrafish were divided into four diet groups: (i) normally fed (NF); (ii) overfed (OF); (iii) NF supplemented with OJe (5 mL/L in fish water; NF + OJe); and (iv) OF supplemented with OJe (OF + OJe). Each week, body weight (BW) and body mass index (BMI) were measured, and, at the end of the fifth week, euthanized zebrafish were processed for both microscopic evaluations and qPCR analyses. Results: In OF zebrafish, OJe significantly decreased both BW and BMI values and lowered the visceral adipose tissue, while it had little effect in the NF group. Moreover, it significantly reduced adipocyte cell size in both NF and OF groups in both visceral and subcutaneous adipose tissues, as well as their number in OF fish. Finally, OJe modulated some obesity-related genes, such as leptin A, ghrelin, orexin, pro-opiomelanocortin (POMC), and neuropeptide Y (NPY), in both gut and brain. Conclusion: This study adds new insights into the anti-obesity properties of orange juice and its flavonoids, suggesting their role as weight management agents through a lipolytic action linked to a restoration of metabolism-regulating gene expression.

Abstract Background: The aim of the present study was to investigate the association of habitual intake of total fatty acids, saturated-, monounsaturated-, polyunsaturated fatty acids, n-3, n-6, and n-9 fatty acids with apelin gene expression in visceral and subcutaneous adipose tissue. Methods: We obtained visceral and subcutaneous adipose tissues from 179 participants (71 non-obese and 105 obese), who had undergone open abdominal surgery. Dietary intake information was gathered with a valid and reliable food frequency questionnaire. The mRNA expression of apelin gene was analyzed by Real-Time PCR. Results: Apelin gene expression was found to be more increased in subcutaneous and visceral adipose tissues in obese than in non-obese participants. Dietary intake of n-3 and polyunsaturated fatty acids was associated with apelin gene expression in subcutaneous and visceral adipose tissues among all categories of weight status after adjusting for total energy intake. Among obese individuals, visceral adipose tissue apelin mRNA levels were associated with total fat intake. Conclusion: Higher apelin gene expression in adipocytes had an association with habitual intake of total fat and n-3 fatty acids in obese and non-obese individuals, indicating a determinative role of quality and quantity of fatty acid intake in a regular diet in adipose tissue adipokine.
