Creatine supplementation has demonstrated several benefits for the muscle, such as increased strength, enhanced tissue repair, and improved ATP resynthesis. This preliminary study aimed to investigate the effects of creatine on the gastrocnemius muscle in dystrophy muscle (MDX) and healthy C57BL/10 mice. <b>Methods:</b> Twenty MDX and C57Bl/10 mice were organized into groups and supplemented or not with creatine in a dosage of 0.3 mg for 8 weeks.

Although studies have shown that estradiol positively contributes to energy metabolism via estrogen receptor alpha (ERα), its role specifically in the liver is not defined. Therefore, this study aimed to evaluate the effects of ERα overexpression, specifically in the liver in mice fed a high-fat diet (HFD). <b>Methods:</b> Male C57BL/6J mice were divided into four groups, vehicle fed with regular chow (RC) (RC-Vehicle); vehicle fed an HFD (HFD-Vehicle); AAV-treated fed with RC (RC-AAV); and AAV-treated fed an HFD (HFD-AAV), for 6 weeks (8-10 mice per group). AAV was administered intravenously to induce ERα overexpression. <b>Results:</b> We demonstrate that overexpression of ERα in RC-fed mice reduces body fat (28%). These mice show increased oxygen consumption in cultured primary hepatocytes, both in basal (19%) and maximal respiration (34%). In HFD-fed mice, we showed a decrease in hepatic TAG content (43%) associated with improved hepatic insulin sensitivity (145%). <b>Conclusions:</b> From this perspective, our results prove that hepatic ERα signaling is responsible for some of the metabolic protective effects of estrogen in mice. Overexpression of ERα improves hepatocyte mitochondrial function, consequently reducing hepatic lipid accumulation and protecting animals from hepatic steatosis and hepatic insulin resistance.

Therefore, the development of BCR-ABL1-independent therapies is encouraged. Renalase (RNLS) is a multifunctional protein that exhibits both enzymatic and non-enzymatic cytokine-like properties, along with potent anti-inflammatory and anti-apoptotic effects. It is expressed in various tissues, including tumors. <b>Methods:</b> We investigated the levels of RNLS in the blood of CML patients in the chronic phase, treatment naïve patients, and those in remission under TKI treatment (either imatinib or nilotinib) and compared them to healthy individuals. <b>Results:</b> Renalase concentration was markedly decreased in treatment-naive CML patients compared to other groups (<i>p</i> = 0.000), while lower levels in the TKI group were not statistically significant compared to controls. The levels correlated negatively with the total leukocyte and neutrophil count (<i>p</i> < 0.05), while a positive correlation was present with CRP levels in treatment naïve patients. <b>Conclusions:</b> Dynamic regulation of RNLS expression and activity is coupled with transcription factors NF-κB and STAT3.
