Cellular metabolic alteration : the voice of monoinsaturated fatty acid as therapeutic target
2010
Stearoyl Co-A desaturase (SCD) is the key enzyme of the metabolism of mono-unsaturated fatty acids (MUFA). Its activity 9 desaturase introduces a double bond cis in position 9 of saturated fatty acids (SFA), induced formation of MUFA. Impaired biosynthesis of MUFA is involved in many diseases such as cancer and cardiovascular disease. Cancer cells have a de novo synthesis of fatty acids increased with an accumulation MUFA. This change in the metabolism of fatty acids is associated with overexpression SCD1 which catalyzes the conversion of saturated fatty acids, monounsaturated fat. Several reports have shown that inhibition of SCD1 leads to blockage of proliferation and induction of apopt…
The metabolic cascade leading to eicosanoid precursors--desaturases, elongases, and phospholipases A2--is altered in Zucker fatty rats.
2010
Abstract Metabolic syndrome characterized by insulin resistance and obesity is accompanied by severe lipid metabolism perturbations and chronic low-grade inflammation. However, many unresolved questions remained regarding the regulation that underlie dyslipidemia, particularly the regulation of the metabolic cascade (synthesis and release) leading to eicosanoid precursors release. This study was undertaken to investigate the regulation of desaturases/elongases and phospholipases A2 during the establishment of metabolic syndrome. Our results showed that delta-6 desaturase as well as elongase-6 expressions were upregulated in 3-month-old Zucker fatty rats as compared to lean littermates, inde…
