Women also showed improvements in testosterone, cholesterol and
TG levels.
Lowering of plasma
TG levels after injection of [3H] triolein - labeled Liposyn particles was associated with a greater uptake of [3H] triolein in the liver, but not in organs such as the heart or skeletal muscle (Figure 8F), as would be expected if LPL activity were enhanced.
(E) Plasma
TG levels of fasted mice before and after injection of 100 μl 20 % Liposyn II particles at the indicated time points.
ApoC - III ASO treatment reduced
TG levels in chylomicrons, VLDL, and remnant particles in all of the mutants as measured by size - exclusion fast protein liquid chromatography (FPLC)(Figure 2, A — E), but had no effect in Ldlr — / — Lrp1fl / fl Alb - Cre + mice (Figure 2F).
Together, these findings suggest that the major mechanism by which ApoC - III affects plasma
TG levels functions independently of LPL.
As reported by Noh et al. (43), tamoxifen transiently increases plasma
TG levels, which return to normal 2 weeks after the last administration.
A reduction in
TG levels also did not cause hepatic steatosis (Figure 3, A and B) or increase the production of ketone bodies (Figure 3C), and at most had only a modest effect on circulating nonesterified free fatty acid (NEFA) levels (Figure 3D).
Again, ApoC - III ASO treatment had no effect on plasma
TG levels in mice lacking both Lrp1 and Ldlr (Figure 5, A and C), as observed with animals fed a standard chow diet (Figure 1) and under postprandial conditions (Figure 3).
These findings suggest that an ASO - mediated reduction of plasma
TG levels depends on LDLR and LRP1.
We also present evidence that TRLs with reduced ApoC - III content do not affect lipolysis and that a reduction in LPL expression and activity does not suppress the impact of ASO inhibition on lowering plasma
TG levels.
However, an increase in plasma
TG levels also occurs in ApoC - III — transgenic mice that are deficient in ApoE (20, 35).
However, a recent clinical study showed that lowering plasma ApoC - III levels with volanesorsen, a generation 2.0 + ApoC - III — specific antisense oligonucleotide (ASO), dramatically lowered elevated plasma
TG levels in patients who have genetic defects in LPL (familial chylomicronemia syndrome [FCS]-RRB-(16).
In chow - fed animals, ApoC - III ASO reduced fasting plasma
TG levels by 30 % to 45 % in animals defective in hepatic Ndst1 and Ldlr and in animals with combined deletions of Ndst1 and Lrp1 or Ldlr (Figure 1, D and E).
However, the ASO had no effect on plasma
TG levels in mice lacking both Lrp1 and Ldlr (Ldlr — / — Lrp1fl / fl Alb - Cre +)(Figure 1, D and E).
Elevated plasma
TG levels represent a risk factor for CVD in humans, and an adjusted analysis of patients in the Framingham Heart Study suggests that each decrease of 1 mg / dl in plasma ApoC - III levels is associated with a 4 % decrease in CVD risk (11), further supporting the potential therapeutic benefit of suppressing plasma ApoC - III levels in humans to reduce CVD.
Plasma
TG levels were determined 2 weeks after the last tamoxifen injection.
Total cholesterol and
TG levels in plasma were determined using kits from Genzyme or Thermo Fisher Scientific.
(E) Liver
TG levels in mutant mice on a high - fat diet treated for 5 weeks with control or ApoC - III ASO (n = 3 — 5 / group).
(D) Fasting plasma
TG levels in mutant mice treated for 4 weeks with control or ApoC - III ASO (n = 5 — 10 / group).
We determined that a murine - specific ApoC - III — targeting ASO reduces fasting
TG levels through a mechanism that is dependent on low - density lipoprotein receptors (LDLRs) and LDLR - related protein 1 (LRP1).
The high - fat diet raised plasma
TG levels in Ldlr — / — , Ldlr — / — Ndst1fl / fl Alb - Cre +, and Ldlr — / — Lrp1fl / fl Alb - Cre + mice, reaching values of 515 to 1,045 mg / dl (Figure 5A).
However, the ApoC - III ASO did not lower
TG levels in mice lacking both LDLR and LRP1.
Similarly, inactivating mutations affecting the expression of APOC3 in humans led to reduced plasma
TG levels (8) and protection against CVD (9 — 11).
While LPL - deficient patients had higher
TG levels than were detected in the LPL - deficient mice, the
TG levels in the mice were not dissimilar from those seen in patients who strictly adhered to a low - fat diet that might be viewed as the equivalent of mouse chow.
A comparable reduction in plasma
TG levels occurred after heparin injection of mice treated with ApoC - III ASO (Figure 7A).
Total cholesterol and
TG levels were determined enzymatically as described above.
Large - scale genetic and clinical investigations are needed to clarify the effects of pharmacologic lowering of LDL - C and
TG levels to gauge dysglycemic associations.»
Michael V. Holmes, M.D., Ph.D., of the University of Oxford, England, and colleagues examined the associations of LDL - C, HDL - C, and
TG levels with CAD and diabetes through mendelian randomization (MR) using conventional MR and making use of newer approaches using genetics.
An analysis using genetics finds that increased low - density lipoprotein cholesterol (LDL - C), high - density lipoprotein cholesterol (HDL - C), and possibly triglyceride (TG) levels are associated with a lower risk of diabetes, and increased LDL - C and
TG levels are associated with an increased risk of coronary artery disease, according to a study published online by JAMA Cardiology.
Increased LDL - C, HDL - C, and possibly
TG levels were associated with a lower risk of diabetes.
«Although further studies are needed to examine whether specific pathways or lipid subtypes are implicated, our findings inform potential expected downstream consequences of interventions affecting lipid traits and provide cautionary evidence that therapeutics that lower LDL - C and
TG levels may have dysglycemic [abnormal blood sugar levels] effects,» the authors write.
Lipoprotein lipid profile disturbances associated with an elevated
TG level include low High Density Lipoprotein (HDL) cholesterol and HDL particle (HDL - P), and a predominance of small dense Low Density Lipoprotein (LDL) and LDL particle (LDL - P).

At a mechanistic
level, thyroid autoimmunity induced by iodine is associated with synthesis of
TG antibodies and the unmasking of a cryptic epitope of thyroglobulin, which is normally sequestered and unavailable to the immune system (19).
In individuals with anti-thyroid peroxidase (TPO) or anti-thyroglobulin (
TG) antibodies, the incidence of elevated TSH increased with greater
levels of iodine intake (18).
In fact, groups with the aforementioned thyroid diseases, as well as individuals with positive
TG or TPO antibodies, have been demonstrated to exhibit significantly higher
levels of urinary iodine, the main indicator of iodine nutritional status, compared to healthy controls (3).
