Effect of green cardamom on the expression of genes implicated in obesity and diabetes among obese women with polycystic ovary syndrome: a double blind randomized controlled trial.

BACKGROUND: Polycystic ovary syndrome (PCOS) is an endocrine disease in which related to obesity, metabolic disorders and is considered as one of the main causes of infertility in women. This trial was investigated the effects of green cardamom on the expression of genes implicated in obesity and diabetes among obese women with PCOS. METHODS: One hundred ninety-four PCOS women were randomly divided two groups: intervention (n = 99; 3 g/day green cardamom) and control groups (n = 95). All of them were given low calorie diet. Anthropometric, glycemic and androgen hormones were assessed before and after 16-week intervention. The reverse transcription-polymerase chain reaction (RT-PCR) method was used to measure fat mass and obesity-associated (FTO), peroxisome proliferative activating receptor- (PPAR-), carnitine palmitoyltransferase 1A (CPT1A), acetyl-CoA carboxylase beta (ACAB), leptin receptor (LEPR), ghrelin, and lamin A/C (LAMIN) genes expression in each group. RESULTS: Anthropometric indices were significantly decreased after intervention in both two studied groups. Glycemic indices and androgen hormones were significantly improved in the intervention group compared to the control group. The expression levels of FTO, CPT1A, LEPR, and LAMIN were significantly downregulated compared to control group (P < 0.001), as well as, PPAR-y was significantly upregulated in the intervention group after intervention with green cardamom compared to control group (P < 0.001). CONCLUSION: This current study showed that the administration of green cardamom is a beneficial approach for improving anthropometric, glycemic, and androgen hormones, as well as obesity and diabetes genes expression in PCOS women under the low-calorie diet. TRIAL REGISTRATION: This trial was registered with the Iranian Clinical Trials Registry (registration number: IRCT20200608047697N1). 1 August, 2020; https://www.irct.ir/trial/48748.

Distribution of HBB Gene Mutations in the Kurdish Population of Ilam Province, West Iran.

ß-Thalassemia (ß-thal) is one of the most common diseases in Iran. Here, we report the spectrum of HBB gene mutations in 176 Kurdish ß-thal carriers from the northern part of Ilam Province, Iran. The amplification refractory mutation system-polymerase chain reaction (ARMS-PCR) technique was used to identify common ß-globin gene mutations observed in Iran. Samples negative on ARMS-PCR were analyzed by direct sequencing of the ß-globin gene. In total, 12 different mutations were identified on the ß-globin gene. The mutations of IVS-II-1 (G>A) (HBB: c.315+1G>A), codons 8/9 (+G) (HBB: c.27_28insG), codons 36/37 (-T) (HBB: c.112delT) and IVS-I-110 (G>A) (HBB: c.93-21G>A), were the most prevalent mutations in our samples, with frequencies of 59.09, 10.80, 7.95 and 7.39%, respectively. In general, the mutation spectrum of the ß-globin gene in the northern part of Ilam Province is most similar to that in other western provinces of Iran. On the other hand, due to the high prevalence of carriers and ß-thal major (ß-TM) patients in this province, our results can be helpful in identifying carriers as well as at-risk fetuses through the prenatal diagnosis program.

Severe α-Thalassemia Due to Compound Heterozygosity for Hb Adana (α59 Gly>Asp) (HBA1: c.179G > A) and Codon 127 (A > T) (HBA2: c.382A > T) in an Iranian Family.

We describe a novel compound heterozygous genotype which consists of two point mutations named Hb Adana (HBA1: c.179G>A) and codon 127 (HBA2: c.382A>T) in a Kurdish family with two girls affected with severe α-thalassemia (α-thal). Both patients (the proband and her sister) had a history of splenectomy during childhood. Although the proband had no blood transfusion history, her affected sister has had two blood transfusions so far. In conclusion, diagnosing and reporting new genotypes on the α-globin genes will improve our knowledge about complicated genotype-phenotype correlations in α-thal disorder.

The Spectrum of α-Thalassemia Mutations in Kurdistan Province, West Iran.

In order to identify the α-thalassemia (α-thal) mutation spectrum in Kurdistan Province, West Iran, a total of 217 individuals, including 154 α-thal carriers and 63 normal subjects were investigated in this study. Molecular analysis of α1- and α2-globin genes using multiplex gap-polymerase chain reaction (gap-PCR), amplification refractory mutation system (ARMS)-PCR or direct DNA sequencing, showed 11 different α-globin variants. The -α3.7 (rightward) deletion (NG_000006.1: g.34164_37967del3804) (70.32%), polyadenylation signal (polyA2) site (AATAAA>AATGAA) (αpolyA2α) (HBA2: c.*92A>G) (7.74%), -α4.2 (leftward) deletion (6.45%) and codon 59 (or Hb Adana) (G>A) (ααcodon 59) (HBA1: c.179G>A) (4.52%) were the most frequent mutations in the present study. In conclusion, the spectrum of α-thal mutations in Kurdistan Province is closest to that in western provinces of Iran (Kurdish and Laki populations). In addition, it was revealed that the codon 59 mutation is common in the Kurdish population. On the other hand, despite the same ethnic background of Kurds in Iran and Iraq, the - -MED I double gene deletion and polyA2 point mutation have different distributions in these two populations. Therefore, further studies are needed to identify the cause of these differences.

The Spectrum of α-Thalassemia Mutations in the Lak Population of Iran.

α-Thalassemia (α-thal) is one of the most common genetic disorders worldwide. The aim of this study was to investigate for the first time the α-thal mutation spectrum in the Lak population living in Lorestan Province, Iran. One hundred and seventy-six α-thal carriers participated in the study. Multiplex gap-polymerase chain reaction (gap-PCR), amplification refractory mutation system (ARMS)-PCR and direct sequencing were used for the detection of different mutations on the α-globin (HBA1 and HBA2) genes. A total of 11 different mutations was identified. The -α3.7 (rightward; NG_000006.1: g.34164_37967del3804) deletion was observed most frequently (56.35%), followed by α-5 ntα (HBA2: c.95+2_95+6delTGAGG), αpolyA2α (HBA2: c.*92A>G) and - -MED I (NG_000006.1: g.24664_41064del16401), with frequencies of 15.47, 9.39, and 6.08%, respectively. These four mutations accounted for more than 87.0% of the total mutated alleles. Moreover, 19 different genotypes were identified. The types and distribution pattern of the mutations identified in this study, in comparison with other studies conducted in Iran, was most similar to the Kurdish population of Kermanshah Province, Iran. Due to the lack of information on α-thal in Lorestan Province, it was not possible to compare the mutation spectrum in the Lur and Lak populations. In conclusion, our results may help in setting up a strategy for an α-thal screening program and genetic counseling in the Lak people.
