Polycystic ovary syndrome (PCOS) is the major cause of anovulatory infertility. Although the genetic basis of PCOS is not well understood, it is a common metabolic and endocrine disorder. This study investigates the possible genomic variants associated with PCOS in Pakistani women from the Punjab region. DNA samples from 96 patients with genetically unrelated PCOS and 96 controls were analyzed by direct sequencing to determine the polymorphisms of different loci on follicle-stimulating hormone receptor (fshr), follicle-stimulating hormone β (fshrβ), luteinizing hormone chorionic gonadotropin (lhcgr), luteinizing hormone β (lhβ), estrogen receptor α (esr1), and estrogen receptor β (esr2) genes. Significant associations were observed within the genotype frequencies, allele frequencies, and multi-single-nucleotide polymorphism (SNP) haplotype analysis of most polymorphisms studied. This study identified new SNPs at positions 605+52 Del/T in lhcgr genes occurring in this particular subpopulation. The strong r (2) value suggests that polymorphisms in the fshr and esr1 genes were in linkage disequilibrium. Our study provides evidence of statistically significant associations between susceptibility to PCOS in Pakistani women and the gene polymorphisms mentioned earlier. This suggests that the susceptible loci for PCOS lie within or very close to the chromosomal regions spanning these genes.

Diabetes is involved in delayed wound healing that can be cured by natural products such as garlic, turmeric, and fibroin extracts. Alloxan monohydrate is used for inducing diabetes in mice. The percent wound contraction of garlic (150 mg/ml), turmeric (100 mg/ml), and fibroin (50 mg/ml), individually and in combinations garlic (150 mg/ml) + fibroin (50 mg/ml), turmeric (100 mg/ml) + fibroin (50 mg/ml), garlic (150 mg/ml) + turmeric (100 mg/ml), and garlic (150 mg/ml) + turmeric (100 mg/ml) + fibroin (50 mg/ml) was checked by measuring evaluating the healing time, and histological analysis. The serum level of MMPs (MMP 2, MMP7, MMP 9), pro-inflammatory cytokines (TNF-α, IL-6, IL-8), and TIMPs were evaluated. With the combination of three extracts (Ga+Tu+Fi) garlic (150 mg/ml), turmeric (100 mg/ml) and fibroin (50 mg/ml), wounds healed in 12 days and had 97.3±2.2% wound contraction. While the positive control (polyfax) and diabetic control (saline) wounds healed in 17- and 19-days with wound contraction of 96.7±1.4% and 96.3±1.1%, respectively. Histological analysis showed that the combination of Ga+Tu+Fi exhibited an increase in the growth of collagen fibers, fibroblasts number, and keratinocytes, and lessened inflammation of blood vessels. The combination of Ga+Tu+Fi significantly alleviated the serum concentration of TNF-α (14.2±0.7 pg/ml), IL-6 (10.0±1.0 pg/ml), IL-8 (16.0±1.5 pg/ml), MMP2 (228.0±18.1 pg/ml), MMP7 (271.0±9.9 pg/ml), and MMP9 (141.0±5.3 pg/ml) to diabetic control. The level of TIMPs (193.0±9.1 pg/ml) was increased significantly with respect to diabetic control. We conclude that the combination of these biomaterials possessed high regenerative and healing capabilities and can be an effective remedy in the healing of chronic wounds in diabetic patients.

Background Endometriosis is a common disease that causes pain and infertility. The heritable predisposition toward endometriosis motivates an interest to identify the genes and genomic variants involved in the pathogenesis of endometriosis. Both genetic and environmental factors contribute to this disease. Here we investigated in Pakistani women the association of endometriosis and single nucleotide polymorphisms (SNP) in genes previously identified in the development of this disease. Methods DNA samples from 52 genetically unrelated endometriosis subjects with endometriosis and 52 randomly selected controls were analyzed by direct sequencing to determine polymorphisms in four genes. These included estrogen receptor alpha (ESR1) (rs2234693 C/T, rs9340799 G/A SNP), estrogen receptor beta (ESR2) (rs4986938 G/A SNP), progesterone receptor (PGR) (rs1042838 G/T, rs10895068 G/A SNPs) and interleukin 10 (IL10) (rs1800871 C/T, rs1800872 C/A and rs1800896 G/A SNPs). Results The allele A at −592, T at −819 and G at −1080 of IL10 and all of the SNPs studied at ESR2 and PGR show strong, statistically significant associations with the disease. However, the genetic variation at ESR1 was distributed similarly among cases and control groups. Conclusion These findings suggest that the functional promoter polymorphism of the IL10 gene, identified by the “ATG” genotype, may contribute to the risk of endometriosis. Genetic variants of ESR2 and PGR gene may also be a risk factor as well as influence the fertility status of patients with endometriosis.
