Induction of thermogenesis in brown and brite adipocytes has recently emerged as a therapeutic target for novel anti obesogenic therapies necessitating the development of methods that can accurately measure heat production in these cells. Modern isothermal microcalorimetric techniques allow for the high throughput quantitative measurement of cellular heat production with limited sample material. Here, we describe the application of this technique for the measurement of thermogenesis in both floating and adherent adipocytes from various murine depots and human cell lines.

Middle-aged obesity, characterized by excessive fat accumulation and systemic energy imbalance, often precedes various health complications. Recent research has unveiled a surprising link between DNA damage response and energy metabolism. Here, we explore the role of Eepd1, a DNA repair enzyme, in regulating adipose tissue function and obesity onset.

Characterizing how organisms respond to transient temperatures may further our understanding of their susceptibility to climate change. Past studies in the freshwater turtle, , have demonstrated that the timing and duration of heat waves can have major implications for the response of genes involved in gonadal development and the production of female hatchlings. Yet, no study has considered how the response of these genes to transient cold snap exposure may affect gonadal development and the production of males.

Rice production is facing substantial threats from global warming associated with extreme temperatures. Here we report that modifying a heat stress-induced negative regulator, a negative regulator of thermotolerance 1 (NAT1), increases wax deposition and enhances thermotolerance in rice. We demonstrated that the C2H2 family transcription factor NAT1 directly inhibits bHLH110 expression, and bHLH110 directly promotes the expression of wax biosynthetic genes CER1/CER1L under heat stress conditions.

The PWWP domain is a conserved motif unique to eukaryotes, playing a critical role in various cellular processes. Proteins containing the PWWP domain are typically found in chromatin, where they bind to DNA and histones in nucleosomes, facilitating chromatin-associated functions. Among these proteins, PWWP-domain containing proteins 2A and 2B (PWWP2A and PWWP2B), identified during the H2A interactome analysis, are DNA methyltransferase-related proteins, that are structurally disordered, except for their PWWP domain.

Obesity, recognized as a metabolic disease and a global epidemic, calls for novel pharmacological interventions. Menthol, an organic compound, has shown promise in increasing energy expenditure and has been proposed as a potential anti-obesity drug. While preclinical studies have demonstrated menthol's preventive effect on body mass gain, none have investigated its efficacy in treating obesity.
