Dataset reporting BCKDK interference in a BCAA-catabolism restricted environment

Area of Science:

• Biochemistry
• Genetics
• Metabolic Disorders

Background:

• Maple Syrup Urine Disease (MSUD) is characterized by reduced branched-chain alpha-ketoacid dehydrogenase complex (BCKDHc) activity.
• BCKDK deficiency is linked to autism and may influence dietary responses.
• Understanding BCKDK's role is crucial for metabolic disease research.

Purpose of the Study:

• To investigate the effect of BCKDK gene knockdown on cellular respiration in MSUD patient fibroblasts.
• To explore the potential of BCKDK knockdown to compensate for reduced BCKDHc activity in MSUD.
• To provide data complementing research on mitochondrial response to BCKDK deficiency in autism.

Main Methods:

• Fibroblasts from an MSUD patient were used.
• BCKDK gene expression was reduced (knockdown).
• Real-time oxygen consumption rate was measured to assess mitochondrial function.

Main Results:

• Data demonstrates the effectiveness of BCKDK gene knockdown in MSUD fibroblasts.
• The study presents oxygen consumption rate data under conditions of BCKDK absence and high branched-chain amino acid (BCAA) concentrations.
• Findings suggest BCKDK knockdown may enhance the deficient BCKDHc activity observed in MSUD.

Conclusions:

• BCKDK knockdown influences cellular respiration in MSUD fibroblasts.
• This data provides insights into the mitochondrial response to BCKDK deficiency.
• The findings may contribute to understanding dietary responses in BCKDK-related conditions.
