| Collection Summary: | Blood samples were collected in a heated hotbox (131°F) through a retrograde intravenous catheter at baseline for glucose and hormone levels, and every 10 min during the clamp to maintain euglycemia. In addition, blood samples were collected every 20 min from 0600 to 0700, 0900 to 1000, and 1200 to 1300 to measure plasma [6,62H2]glucose. At 1330 h, a percutaneous needle muscle biopsy specimen (350–400 mg) was obtained from the vastus lateralis muscle under local anesthesia, immediately frozen in liquid nitrogen, and stored at −80°F for future analysis (27). This biopsy sample was used for analysis of TXNIP mRNA and protein content. The participant remained in the CRU through the remainder of the day and was given a weight-maintenance diet until 2200 h. At 0700 h the following morning, a second muscle biopsy specimen was obtained under local anesthesia, and ∼100 mg was used immediately for mitochondrial function measurements of isolated mitochondria and mtH2O2 emissions (28). The remainder was immediately frozen in liquid nitrogen and stored at −80°F for future analysis, including DAG, ceramide, and amino acid measurements (Fig. 1). |
