Dog (Canine) Polyclonal FADS1 Primary Antibody für ELISA, WB - ABIN547820
Cho, Nakamura, Clarke: Cloning, expression, and fatty acid regulation of the human delta-5 desaturase. in The Journal of biological chemistry 2000
Knock down of FADS1 did not significantly change cholesterol efflux (p=0.70), but knockdown of INSIG1 and LDLR resulted in highly significant reduction of the efflux to HDL (67% and 75% of control, respectively, p<0.001).
genetic association studies in population in Republic of Ireland: Data suggest that SNPs in FADS1 and FADS2 are associated with adiposity and plasma linoleic acid levels in subjects with overweight and obesity. (FADS1 = fatty acid desaturase-1; FADS2 = fatty acid desaturase-2)
genetic association studies in Caucasian population in Victoria, Australia: Data suggest that SNPs in FADS1 (rs174537, rs174547) are associated with erythrocyte levels of linoleic acid and alpha-linolenic acid in subjects with major depressive disorder (MDD); the SNP rs3834458 in FADS2 may also be associated with MDD.
FADS1 role in the oleic acid metabolism
review identified that FADS polymorphism may alter plasma fatty acid composition and play a protective role in the development of type 2 diabetes
FADS1/2 SNPs affect dietary fatty acid metabolism in centrally obese postmenopausal Polish women.
The results of this population-based study provide evidence for a relationship between lipid regulatory gene polymorphisms including GCKR (rs780094), GCKR (rs1260333), FADS (rs174547), and MLXIPL (rs3812316) with dyslipidemia in an Iranian population.
An association was found between the rs174550 FADS1 polymorphism and gestational diabetes mellitus risk.
commonly overexpressed COX in cancer (~90% of colon cancer patients) can be taken advantage to suppress cell growth by knocking down delta-5-desaturase (D5D, a key enzyme that converts DGLA to arachidonic acid). In addition, D5D knockdown along with DGLA supplement may enhance the efficacy of chemotherapeutic drugs
In minor allele carriers of FADS1 and FADS2, plasma arachidonic acid (ARA) content was elevated only at the highest level of ARA consumed in infant formula. ARA level in plasma is reduced by low ARA consumption and by minor alleles in FADS in infants fed ARA-containing formula.
D5D knockdown in conjunction with dihomo-gamma-linolenic acid treatment can also be used to inhibit growth of pancreatic cancer cells via p53 independent pathway.
Our results showed that knockdown of delta-5-desaturase along with DGLA supplement not only significantly inhibited cell migration, but also improved the efficacies of 5-flurouracil and gemcitabine, two frontline chemotherapy drugs currently used in the treatment of colon and pancreatic cancer.
The majority of CpG sites (117 out of 136, 86%) exhibited high levels of methylation with the greatest variability observed at three key regulatory regions-the promoter regions for FADS1 and FADS2 and a putative enhancer site between the two genes.
FADS1 rs174547 and FADS2 rs2727270 genotypes were significantly correlated with decreased HDL-C concentrations, and D5D /D6D activities as estimated as 20:4(n-6)/20:3 (n-6) and 18:3 (n-6)/18:2 (n-6) in a linear pattern in patients with type 2 diabetes
Results indicate that genetic variation in the FADS1 gene, rs174546, influences blood pressure via arachidonic acid and body mass index. Thus, polymorphisms with an impact on the delta-5 desaturase activity may play a role for the blood pressure level mediated through polyunsaturated fatty acids and body mass index.
FADS1 rs174549 polymorphism and fish consumption may be protective factors for oral cancer, with a gene-diet multiplicative interaction
The derived allele of rs174557, which is the common variant in most populations, diminishes binding of PATZ1, a transcription factor conferring allele-specific downregulation of FADS1.
a 2-locus constructed haplotype (rs174547-rs174553) affected gamma-linoleic acid and arachidonic acid concentration in breast milk of Chinese women
This study showed associations between FADS 1/2 SNPs and cognitive performance. rs1535 minor allele homozygosity and rs174448 major allele carriage associated with improved cognitive performance in 8- to 11-y-old boys but not in girls, thereby counteracting existing sex differences.
we determined rs66698963 genotype frequencies from 234 individuals of a primarily vegetarian Indian population and 311 individuals from the US. A much higher I/I genotype frequency was found in Indians (68%) than in the US (18%). A much higher I/I genotype frequency was found in Indians (68%) than in the US (18%). A global I/I genotype of 70% in South Asians, 53% in Africans, 29% in East Asians, and 17% in Europeans
dietary arachidonate regulated the desaturase-elongase pathway in a tissue-specific manner.
Fads1 is an underappreciated regulator of inflammation initiation and resolution, and suggest that endogenously synthesized arachidonic acid and eicosapentaenoic acid are key determinates of inflammatory disease progression and liver X receptor signaling.
Data (including data from studies using knockout mice) suggest that increased dietary intake of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) differentially affects activity of D5D/Fads1 and D6D/Fads2 in specific tissues.
differential PUFA profiles between HET mice and human FADS SNPs suggest low expression of both FADS1 and 2 genes in human minor haplotypes.
Data indicate that delta-5 desaturase (D5D) inhibition was confirmed by determining changes in blood arachidonic acid/dihomo-gamma-linolenic acid (AA/DGLA) profiles.
knockdown of Elovl5, Fads1, or Fads2 decreased the level of Mead acid.
The Systemic disruption of the Fads1 gene reciprocally altered the levels of dihomo-gamma-linolenic acid and AA in mouse tissues, resulting in a profound increase in 1-series-derived and a concurrent decrease in 2-series-derived prostaglandins.

support a significant role for reverse Delta5-desaturase as a natural antisense regulator of Delta5-desaturase
n-3 fatty acid desaturase may have a role in colitis-associated colon cancer in mice
The protein encoded by this gene is a member of the fatty acid desaturase (FADS) gene family. Desaturase enzymes regulate unsaturation of fatty acids through the introduction of double bonds between defined carbons of the fatty acyl chain. FADS family members are considered fusion products composed of an N-terminal cytochrome b5-like domain and a C-terminal multiple membrane-spanning desaturase portion, both of which are characterized by conserved histidine motifs. This gene is clustered with family members FADS1 and FADS2 at 11q12-q13.1\; this cluster is thought to have arisen evolutionarily from gene duplication based on its similar exon/intron organization.
