TLDR
This Review focuses on ceramide signalling and the targeting of specific metabolic junctures to amplify the tumour suppressive activities of ceramide.
Abstract
One crucial barrier to progress in the treatment of cancer has been the inability to control the balance between cell proliferation and apoptosis: enter ceramide. Discoveries over the past 15 years have elevated this sphingolipid to the lofty position of a regulator of cell fate. Ceramide, it turns out, is a powerful tumour suppressor, potentiating signalling events that drive apoptosis, autophagic responses and cell cycle arrest. However, defects in ceramide generation and metabolism in cancer cells contribute to tumour cell survival and resistance to chemotherapy. This Review focuses on ceramide signalling and the targeting of specific metabolic junctures to amplify the tumour suppressive activities of ceramide. The potential of ceramide-based therapeutics in the treatment of cancer is also discussed.

Regulatory Aspects of Oncologicals: Nanosystems Main Challenges

TL;DR: The design and development of engineered nanosystems for disease diagnosis, prevention and treatment has been boosted by significant advances observed in distinct areas and the regulatory environment has been increasingly challenged by key issues, which has been an opportunity to provide clearer guidance for their development.

Sphingosine kinase inhibitors decrease viability and induce cell death in natural killer-large granular lymphocyte leukemia.

TL;DR: The data demonstrate that SPHK1 represents a novel therapeutic target for the treatment of NK-LGL leukemia and shows thatSPHK1 inhibition with SKI-178 leads to decreased JAK-STAT signaling.

The Effect of Counterfactual Information on Outcome Value Coding in Medial Prefrontal and Cingulate Cortex: From an Absolute to a Relative Neural Code

TL;DR: The results suggest that simultaneous presentation of obtained and foregone outcomes promotes relative value representation, and the first comparison of three possible models of neural coding of value signal in mPFC and cingulate cortex that are critical for value-based decisions and behavioral adaptation is provided.

The emergence of acid ceramidase as a therapeutic target for acute myeloid leukemia.

TL;DR: The finding of elevated AC in AML supports the concept that this enzyme represents a novel and realistic therapeutic target for this common leukemia.

AMPK and mTOR regulate autophagy through direct phosphorylation of Ulk1

TL;DR: A molecular mechanism for regulation of the mammalian autophagy-initiating kinase Ulk1, a homologue of yeast ATG1, is demonstrated and a signalling mechanism for UlK1 regulation and autophagic induction in response to nutrient signalling is revealed.

Apoptosis: a link between cancer genetics and chemotherapy.

TL;DR: Understanding the molecular events that contribute to drug-induced apoptosis, and how tumors evade apoptotic death, provides a paradigm to explain the relationship between cancer genetics and treatment sensitivity and should enable a more rational approach to anticancer drug design and therapy.

FoxO3 controls autophagy in skeletal muscle in vivo.

TL;DR: FoxO3 controls the two major systems of protein breakdown in skeletal muscle, the ubiquitin-proteasomal and autophagic/lysosomal pathways, independently and is pointed to as potential therapeutic targets in muscle wasting disorders and other degenerative and neoplastic diseases in which autophagy is involved.

Targeting mitochondria for cancer therapy

TL;DR: The mitochondrial metabolism of cancer cells is deregulated owing to the use of glycolytic intermediates, which are normally destined for oxidative phosphorylation, in anabolic reactions and activation of the cell death machinery by stimulating mitochondrial membrane permeabilization could therefore be promising therapeutic approaches.

Biologically active sphingolipids in cancer pathogenesis and treatment.

TL;DR: This work has shown that ceramide — a central molecule in sphingolipid metabolism — in effect functions as a tumour-suppressor lipid, inducing antiproliferative and apoptotic responses in various cancer cells, and that S1P induces responses that, on aggregate, render S 1P a tumours-promoting lipid.
