24-Methylenecholesterol (Ostreasterol) is a regulator targeting acyl-CoA cholesterol acyltransferase (ACAT) with anti-aging and neuroprotective effects. 24-Methylenecholesterol mimics the effects of nerve growth factor (NGF), can extend yeast lifespan through an anti-oxidative stress mechanism, and exhibits neuroprotective activity in PC12 cells. 24-Methylenecholesterol can reduce intracellular reactive oxygen species (ROS) and malondialdehyde (MDA) levels, activate anti-oxidative stress pathways (such as UTH1, SOD-related genes), and promote synaptic growth.

In Vivo

24-Methylenecholesterol (0.1-1.0% dry feed concentration; dietary supplementation; once daily; 3 weeks) significantly upregulates the expression of head nutritional marker proteins (such as MRJP1, MRJP4-7), improves antioxidant enzyme activities and promoted larval development in the Apis mellifera model^[2].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

Apis mellifera worker bees (female, newly emerged, 80-100 mg body weight), nutritional physiology model^[2]
Dosage:

0.1% (S1), 0.25% (S2), 0.5% (S3), 0.75% (S4), 1.0% (S5) 24-Methylenecholesterol dissolved in acetone and mixed into synthetic diets (final acetone concentration <0.5%)
Administration:

Oral administration via synthetic diet, replaced daily, treatment for 3 weeks starting from newly emerged adulthood
Result:

Treatment with 24-Methylenecholesterol at 0.1-1.0% dry diet concentration significantly altered the head proteome of worker bees.
Compared to the control group, the mean relative abundances of major royal jelly proteins (MRJP1, MRJP4, MRJP5, MRJP7)-key nutritional markers involved in brood food synthesis-were upregulated by 20-35% in the S3-S5 groups (0.5-1.0% sterol).

Help & FAQs

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.
