trans-Vaccenic acid is a naturally occurring trans fatty acid (TFA). trans-Vaccenic acid inhibits nasopharyngeal carcinoma (NPC) cell growth and induces apoptosis through the inhibition of Bad/Akt phosphorylation. trans-Vaccenic acid is a precursor for the synthesis of saturated fatty acid in the rumen and of conjugated Linoleic acid (CLA) at the tissue level. trans-Vaccenic acid exerts hypolipidemic effects in a rat model of obesity.

trans-Vaccenic acid is reduced in the rumen to form stearic acid or is desaturated by Δ9-desaturase in the mammary tissue to produce cis-9, trans-11 C18:2, which is an abundant conjugated Linoleic acid isomer in meat and milk^[1].
trans-Vaccenic acid (0-200 μM; 24 h) inhibits NPC cell viability in a dose-dependent manner^[2].
trans-Vaccenic acid (25-100 μM; 24 h) induces apoptosis in NPC cells in a dose-dependent manner. trans-Vaccenic acid significantly increases the levels of cleaved PARP and cleaved caspase-3 in a time-dependent manner^[2].
trans-Vaccenic acid (25-100 μM; 24 h) induces apoptosis in NPC cells through Akt and bad inactivation^[2].

Result:

Incubation of 5-8F cells with 25, 50 or 100 μM for 24 h caused 7.67, 12.9% or 35% increases in total apoptosis, respectively.
Similarly, after incubation with 25 50 or 100 μM CNE-2, the percentage of apoptotic cells was increased by 12.9, 15.1% or 22.3%, respectively. Significantly increased the levels of cleaved PARP and cleaved caspase-3 in a time-dependent manner.

Animal Model:

Obese JCR:LA-cp rats^[3].
Dosage:

1% w/w

Diet; for 8 weeks
Result:

Reduced total body fat and decreased adipocyte size.
Increased metabolic rate concomitantly with an increased preference for whole-body glucose utilization for oxidation and increased insulin sensitivity.

Stock Solution Working Solution

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for In Vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Working Solution

For the following dissolution methods, please prepare the working solution directly:

It is recommended to prepare fresh solutions and use them promptly within a short period of time.

The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
