Study of monogenic forms of obesity has demonstrated the pivotal role of the central leptin–melanocortin pathway in controlling energy balance, appetite and body weight1. The majority of loss-of-function mutations (mostly recessive or co-dominant) have been identified in genes that are directly involved in leptin–melanocortin signaling. These genes, however, only explain obesity in <5% of cases, predominantly from outbred populations2. We previously showed that, in a consanguineous population in Pakistan, recessive mutations in known obesity-related genes explain ~30% of cases with severe obesity3,4,5. These data suggested that new monogenic forms of obesity could also be identified in this population. Here we identify and functionally characterize homozygous mutations in the ADCY3 gene encoding adenylate cyclase 3 in children with severe obesity from consanguineous Pakistani families, as well as compound heterozygous mutations in a severely obese child of European-American descent. These findings highlight ADCY3 as an important mediator of energy homeostasis and an attractive pharmacological target in the treatment of obesity.

The timing of both entry and permanence of core-clock proteins in the nucleus is critical to maintain the correct pace of the clock mechanism. Several such proteins, namely CRYPTOCHROMEs (CRY), PERIODs (PER), and BMAL1, were recently shown to contain nuclear transport signals that facilitate their "shuttling" between the nucleus and the cytoplasm. This type of dynamic intracellular movement not only regulates protein localization, but also often affects functions by determining interactive partners and protein turnover. Because most clock genes have been identified by genetic screening in Drosophila and by gene knockdown in mammals, it is important to develop cellular techniques to study the structure-function and regulation of the corresponding proteins. Here we present working protocols for immunofluorescence studies of clock proteins in mammalian cultured cells. This technique allows the visualization in the cell of one or multiple proteins at the same time.

In mammals, the central circadian pacemaker resides in the hypothalamic suprachiasmatic nucleus (SCN), but circadian oscillators also exist in peripheral tissues. We have used wild-type and cryptochrome (mCry)-deficient mouse embryonic fibroblasts (MEFs) to demonstrate that the peripheral oscillator is mechanistically very similar to the oscillator in the SCN. Following serum shock activation, fibroblasts are able to sustain an SCN-like temporal expression profile of all known genes (i.e., antiphase oscillation of Bmal1 and Dbp genes), but are not able to produce oscillations in the absence of functional mCry genes. Remarkably, the analysis of mCry1-/- and mCry2-/- MEFs revealed the capacity to control period length in immortalized cell lines. Thus, the use of mammalian cells has become one of the most convenient methods for monitoring the molecular clock machinery and analyzing clock proteins at the functional/structural level. Here, we present the necessary protocols to (1) derive and culture a fibroblast cell line from wild-type and knockout mouse skin and (2) transfect cells at high efficiency to use in functional clock-protein studies.
