Objectives: Lupron 11.25 mg has both a narrow indication and a high cost compared to other Lupron presentations. Prior to our study initiation there was no clear distinction between presentations when ordering within the health-system's Electronic Health Record (EHR).

Article Synopsis
  • Researchers are studying patient-derived organoids (PDOs) to see if they can help predict how patients with gastrointestinal (GI) cancers will react to treatments.
  • They created PDOs from cancer samples and found that about 80% of the time, the PDO responses matched the actual responses of the patients.
  • The type of culture media used for growing the PDOs can change how they respond to treatments, which is important for choosing the right therapy for patients with GI cancers.

The modulation of GLI2, an oncogenic transcription factor commonly upregulated in cancer, is in many cases not due to genetic defects, suggesting dysregulation through alternative mechanisms. The identity of these molecular events remains for the most part unknown. Here, we identified TFII-I as a novel repressor of GLI2 expression.

International experts gathered at the Mayo Clinic (Rochester MN, USA) on February 27th-28th, 2017 for a meeting entitled 'Basic and Translational Facets of the Epigenetics of GI Diseases'. This workshop summarized recent advances on the role of epigenetics in the pathobiology of gastrointestinal (GI) diseases. Highlights of the meeting included recent advances on the involvement of different epigenetic mechanisms in malignant and nonmalignant GI disorders and the epigenetic heterogeneity exhibited in these diseases.

Cancer patients are commonly affected by cachexia, a wasting process involving muscle and fat. Specifically, loss of the muscle compartment has been associated with poor prognosis and suboptimal response to therapy. Nutritional support has been ineffective in treating this process leading to investigations into the underlying molecular processes governing muscle catabolism.

Stromal cells of the tumor microenvironment have been shown to play important roles in both supporting and limiting cancer growth. The altered phenotype of tumor-associated stromal cells (fibroblasts, immune cells, endothelial cells etc.) is proposed to be mainly due to epigenetic dysregulation of gene expression; however, only limited studies have probed the roles of epigenetic mechanisms in the regulation of stromal cell function.
