Astrocytes, which are homeostatic cells of the central nervous system (CNS), display remarkable heterogeneity in their morphology and function. Besides their physical and metabolic support to neurons, astrocytes modulate the blood-brain barrier, regulate CNS synaptogenesis, guide axon pathfinding, maintain brain homeostasis, affect neuronal development and plasticity, and contribute to diverse neuropathologies via secreted proteins. The identification of astrocytic proteome and secretome profiles has provided new insights into the maintenance of neuronal health and survival, the pathogenesis of brain injury, and neurodegeneration. Recent advances in proteomics research have provided an excellent catalog of astrocyte-secreted proteins. This review categorizes astrocyte-secreted proteins and discusses evidence that astrocytes play a crucial role in neuronal activity and brain function. An in-depth understanding of astrocyte-secreted proteins and their pathways is pivotal for the development of novel strategies for restoring brain homeostasis, limiting brain injury/inflammation, counteracting neurodegeneration, and obtaining functional recovery.

When Clarity Is Crucial: Regulating Ocular Surface Immunity
Publication date: Available online 14 December 2017

The ocular surface is a unique mucosal immune compartment in which anatomical, physiological, and immunological features act in concert to foster a particularly tolerant microenvironment. These mechanisms are vital to the functional competence of the eye, a fact underscored by the devastating toll of excessive inflammation at the cornea – blindness. Recent data have elucidated the contributions of specific anatomical components, immune cells, and soluble immunoregulatory factors in promoting homeostasis at the ocular surface. We highlight research trends at this distinctive mucosal barrier and identify crucial gaps in our current knowledge.

Hypoxia Inducible Factors Modify Collagen I Fibers in MDA-MB-231 Triple Negative Breast Cancer Xenografts
Publication date: February 2018

Hypoxia inducible factors (HIFs) are transcription factors that mediate the response of cells to hypoxia. HIFs have wide-ranging effects on metabolism, the tumor microenvironment (TME) and the extracellular matrix (ECM). Here we investigated the silencing effects of two of the three known isoforms, HIF-1α and HIF-2α, on collagen 1 (Col1) fibers, which form a major component of the ECM of tumors. Using a loss-of-function approach for HIF-1α or 2α or both HIF-1α and 2α, we identified a relationship between HIFs and Col1 fibers in MDA-MB-231 tumors. Tumors derived from MDA-MB-231 cells with HIF-1α or 2α or both HIF-1α and 2α silenced contained higher percent fiber volume and lower inter-fiber distance compared to tumors derived from empty vector MDA-MB-231 cells. Depending upon the type of silencing, we observed changes in Col1 degrading enzymes, and enzymes involved in Col1 synthesis and deposition. Additionally, a reduction in lysyl oxidase protein expression in HIF-down-regulated tumors suggests that more non-cross-linked fibers were present. Collectively these results identify the role of HIFs in modifying the ECM and the TME and provide new insights into the effects of hypoxia on the tumor ECM.

A Low-Toxicity DNA-Alkylating N-Mustard-Quinoline Conjugate with Preferential Sequence Specificity Exerts Potent Antitumor Activity Against Colorectal Cancer

Efficacy and safety are fundamental prerequisites for anticancer drug development. In the present study, we explored the anti–colorectal cancer (CRC) activity of SL-1, a DNA-directed N-mustard-quinoline conjugate. The N-mustard moiety in SL-1 induced DNA strand breaks, interstrand cross-links (ICLs), G2/M arrest, and apoptosis, whereas its quinoline moiety preferentially directed SL-1 to target the selective guanine sequence 5′-G-G/C-N-G-C/T-3′. Notably, SL-1 was highly cytotoxic to various CRC cell lines. Experiments using xenograft models revealed that SL-1 was more potent than 5-fluorouracil (5-FU) and oxaliplatin for suppressing the growth of RKO and RKO-E6 (oxaliplatin-resistant subline) cells as well as metastatic SW620 cells. In addition, SL-1 combined with 5-FU was more effective than oxaliplatin and 5-FU for suppressing RKO or SW620 cell growth in mice. Significantly, compared with cisplatin, oxaliplatin, or 5-FU, SL-1 alone or in combination with 5-FU did not cause obvious kidney or liver toxicity in ICR mice. In summary, SL-1, a DNA-directed alkylating agent, is established as an anti-CRC agent with high efficacy and low toxicity and thus warrants further development for the treatment of CRC patients.
