AIM: Nicotinamide N-methyltransferase (NNMT) is a novel regulator of energy homeostasis in adipose tissue. NNMT expression is higher in obese mice than in lean mice, and NNMT knockdown prevents diet-induced obesity. Little is known about the regulation of enzyme activity during the development of obesity. The aim of this study was to analyze NNMT activity in tissues of mice with incipient and established obesity. METHODS: A fluorescence-based, sensitive, low-volume, high-throughput method was developed to assay NNMT activity...

Raelene E Maser, M James Lenhard, Ryan T Pohlig, P Babu Balagopal, Raafat Abdel-Misih
PURPOSE: Surgical treatment for primary hyperparathyroidism (PHPT) improves bone metabolism. Osteocalcin (OC) and its undercarboxylated form (ucOC) are associated with bone and energy metabolism. Osteopontin (OPN), a multifunctional protein expressed in bone, is involved in resorption, along with β-carboxyl-terminal cross-linking telopeptide of type 1 collagen (β-CTX), and osteoprotegerin (OPG). Our aim was to investigate these biomarkers of bone metabolism in patients with PHPT. METHODS: We examined 30 individuals with PHPT, in a clinical research facility, before and 1 month following parathyroidectomy...

BACKGROUND: Mitophagy is a form of autophagy for the elimination of mitochondria. Mitochondrial content and function are reduced in the skeletal muscle of patients with type 2 diabetes mellitus (T2DM). Physical training has been shown to restore mitochondrial capacity in T2DM patients, but the role of mitophagy has not been examined in this context. This study analyzes the impact of a 3-month endurance training on important skeletal muscle mitophagy regulatory proteins and oxidative phosphorylation (OXPHOS) complexes in T2DM patients...

PURPOSE: Differentiated thyroid cancer is the most common endocrine malignancy. Recurrences (5-20%) are the main reason for follow-up. Thyroglobulin (Tg) has proven to be an excellent disease marker, but thyroglobulin-antibodies (Tg-Ab) may interfere with Tg measurement, leading to over or underestimation. It is proposed that the Tg-Ab trend can be used as a marker for disease recurrence, yet few studies define trend and have a long-term follow-up. The objective of our study was to investigate the value of a well-defined Tg-Ab trend as a surrogate marker for disease recurrence during long-term follow-up...

BACKGROUND: Fine-needle aspiration biopsy (FNAB) cannot distinguish a follicular thyroid carcinoma (FTC) from a follicular adenoma in follicular lesions. We designed this study to determine whether the preoperative thyroglobulin (Tg) and change in serum Tg during thyroid-stimulating hormone (TSH) suppression can predict FTC in thyroid nodules with a cytological diagnosis of follicular lesion. METHODS: Among 854 patients who underwent thyroid surgery, the 198 patients who presented with thyroid nodules with a cytological diagnosis of follicular lesion were analyzed...

PURPOSE: Fibroblast growth factor 23 (FGF23) is a hormone regulating phosphate metabolism. Excessive actions of FGF23 cause several types of FGF23-related hypophosphatemic rickets/osteomalacia. Recently, it was reported that FGF23 levels were independently correlated with left ventricular hypertrophy (LVH) in patients with chronic kidney disease (CKD). In addition, FGF23 was also shown to cause cardiac hypertrophy directly acting on cardiomyocytes. However, there is no study indicating the correlation between FGF23 and LVH in adult patients with FGF23-related hypophosphatemic rickets/osteomalacia...
