in vitroで分化したマウス脂肪組織および初代前駆脂肪細胞における脂肪分解の速度の測定

Overview

This study presents a protocol for measuring the lipolytic rates in adipocytes, utilizing both cultured cells and ex vivo adipose tissue from murine models. The findings significantly demonstrate the differences in lipolytic rates under basal and stimulated conditions.

Key Study Components

Research Area

• Adipocyte metabolism
• Lipolysis measurement
• Cutting-edge metabolic assays

Background

• Understanding triglyceride lipolysis is crucial for insights into metabolic processes.
• Utilizing murine models aids in the exploration of adipose tissue responses.
• The relevance of free fatty acids and glycerol as metabolic byproducts is emphasized.

Methods Used

• Serial sampling and media collection from cultured adipocyte and ex vivo tissue.
• Murine adipose tissue was used for comparative analysis.
• Enzymatic assays for quantifying free fatty acid and glycerol production.

Main Results

• Stimulated lipolytic rates were significantly higher compared to basal rates.
• FFA-to-glycerol molar ratios indicated varying sources of glycerol amidst different conditions.
• Results validate the protocol's applicability across model systems.

Conclusions

• The study successfully illustrates how lipolytic rates can be precisely measured in both in vitro and ex vivo environments.
• These findings have broad implications for understanding metabolic disorders associated with adipose tissue function.
