Disease relevance of PLIN

  • OBJECTIVE: The objective of the study was to examine the association of several polymorphisms at the perilipin (PLIN) locus with obesity and weight reduction in response to a low-energy diet in obese patients [1].
  • The current study investigated the association between PLIN polymorphisms and the combination of hypertension and obesity (HO) and the related clinical features [2].
  • In summary, our data suggest that common alleles at the PLIN locus modulate body weight and metabolic variables in humans [3].
  • CONCLUSIONS: We show the presence and induction of perilipin in atheroma [4].
  • Obese subjects carrying the 11482G>A polymorphism at the perilipin locus are resistant to weight loss after dietary energy restriction [1].
 

Psychiatry related information on PLIN

 

High impact information on PLIN

  • We found that truncated DRPLA proteins containing an expanded polyglutamine stretch form filamentous peri- and intranuclear aggregates and undergo apoptosis [9].
  • Sequence-specific catalytic DNA enzymes inhibited rat PAI-1 mRNA and protein expression in peri-infarct endothelium within 48 h of administration, and maintained down-regulation for at least 2 wk [10].
  • Bone loss was significantly associated with lower androgen concentrations in premenopausal women, and with lower estrogens and androgens in peri- and postmenopausal women [11].
  • Lymphocytes had peri- and intraganglionic location [12].
  • CONCLUSIONS: EUS-FNA accurately and safely evaluates solid peri-intestinal lesions and improves lymph node staging accuracy [13].
 

Chemical compound and disease context of PLIN

 

Biological context of PLIN

  • DESIGN: This study was a 1-yr randomized (depending on the PLIN genotype) trial with three follow-up evaluations [1].
  • No associations between PLIN haplotypes and obesity risk were found in Chinese. To simplify the haplotype analyses we used a subgroup of three SNPs (11482G>A, 13041A>G, and 14995A>T) in positive linkage disequilibrium [18].
  • Moreover, individual SNP analyses demonstrated that the PLIN 14995A>T SNP is the most informative single genetic marker for the observed haplotype association, being significantly associated with increased obesity risk in both Malays OR 2.28 (95% CI 1.45-3.57) and Indians OR 2.04 (95% CI 1.08-3.64) [18].
  • Polymorphism 1243 in the PLIN gene did not seem to be associated with HO but with TC levels in Chinese. The PLIN gene may be involved in human lipid metabolism [2].
  • Genetic variation at the perilipin (PLIN) locus is associated with obesity-related phenotypes in White women [3].
 

Anatomical context of PLIN

 

Associations of PLIN with chemical compounds

  • However, there was no significant relationship between perilipin expression and blood NEFA, nor was there a significant relationship between perilipin expression and insulin resistance, using the insulin sensitivity index derived from the iv glucose tolerance test with minimal modeling [20].
  • We conclude that ritonavir decreases PDE3B and perilipin protein expression and affects both basal and catecholamine-stimulated lipolysis in 3T3-L1 adipocytes primarily through actions at sites downstream of PKA [21].
  • Adipocyte content of perilipin was inversely correlated with the circulating concentrations of glycerol (r=0.62) and non-esterified fatty acids (n=0.49) [14].
  • RESULTS: Basal and noradrenaline-induced rates of lipolysis were two to fourfold increased (p<0.01) and perilipin protein content decreased 50% (p=0.005) in adipocytes of the obese women [14].
  • Testosterone caused a depot-specific 50% reduction of the protein expression of hormone-sensitive lipase and beta(2)-adrenoceptors in differentiated subcutaneous pre-adipocytes, but no change in beta(1)-adrenoceptors, protein kinase A subunits or perilipin expression [22].
 

Regulatory relationships of PLIN

 

Other interactions of PLIN

  • We have evaluated the association between several polymorphisms at the perilipin (PLIN) locus (PLIN1 : 6209T > C, PLIN4 : 11482G > A, PLIN5 : 13041A > G, and PLIN6 : 14995A > T) with obesity-related phenotypes in 1589 White subjects randomly selected from a general Spanish population [3].
  • In addition, there was no significant relationship between perilipin and adipocyte or systemic inflammatory markers, such as TNFalpha, IL-6, and adiponectin [20].
  • On differentiated human preadipocytes, ANP-mediated lipolysis, associated with an increased phosphorylation of HSL and of perilipin A, was strongly decreased by treatment with the inhibitor of the cGMP-dependent protein kinase I (cGKI), Rp-8-pCPT-cGMPS [24].
  • The present study was undertaken to reveal whether the mammalian lipid body proteins perilipin A, adipose differentiation-related protein, and tail-interacting protein of 47 kDa (TIP47), which comprise the so called PAT family proteins, and the maize (Zea mays L.) oleosin are targeted to prokaryotic TAG bodies in vivo [25].
  • RESULTS: A 48-h incubation with TNF-alpha resulted in a pronounced increase in lipolysis, which was paralleled by a decrease in the mRNA and protein expression of PLIN [23].
