AbstractThe estrogen-related receptor alpha (ERRα) is a primary regulator of mitochondrial energy metabolism, function and dynamics, and has been implicated in autophagy and immune regulation. ERRα is abundantly expressed in the intestine and in cells of the immune system. However, its role in inflammatory bowel disease (IBD) remains unknown. Here, we report a protective role of ERRα in the intestine. We found that mice deficient in ERRα were susceptible to experimental colitis, exhibiting increased colon inflammation and tissue damage. This phenotype was mediated by impaired compensatory proliferation of intestinal epithelial cells (IEC) following injury, enhanced IEC apoptosis and necrosis and reduced mucus-producing goblet cell counts. Longitudinal analysis of the microbiota demonstrated that loss of ERRα lead to a reduction in microbiome α-diversity and depletion of healthy gut bacterial constituents. Mechanistically, ERRα mediated its protective effects by acting within the radio-resistant compartment of the intestine. It promoted disease tolerance through transcriptional control of key genes involved in intestinal tissue homeostasis and repair. These findings provide new insights on the role of ERRα in the gut and extends our current knowledge of nuclear receptors implicated in IBD.

AbstractAdvances in the field of surgical oncology have turned metastatic colorectal cancer of the liver from a lethal disease to a chronic disease and have ushered in a new era of multimodal therapy for this challenging illness. A better understanding of tumor behavior and more effective systemic therapy have led to the increased use of neoadjuvant therapy. Surgical resection remains the gold standard for treatment but without the size, distribution, and margin restrictions of the past. Lesions are considered resectable if they can safely be removed with tumor-free margins and a sufficient liver remnant. Minimally invasive liver resections are a safe alternative to open surgery and may offer some advantages. Techniques such as portal vein embolization, association of liver partition with portal vein ligation for staged hepatectomy, and radioembolization can be used to grow the liver remnant and allow for resection. If resection is not possible, nonresectional ablation therapy, including radiofrequency and microwave ablation, can be performed alone or in conjunction with resection. This article presents the most up-to-date literature on resection and ablation, with a discussion of current controversies and future directions.
