Abstract: The presently disclosed subject matter provides compositions and methods comprising improvements of a CRISPR system (e.g. CRISPR associated (Cas) 9 (CRISPR-Cas9, non-Cas9 CRISPR systems). Such compositions may comprise modifications to the H1 promoter region, addition of 5?UTR modifications, different orthologous sequences of the H1 promoter, novel compact bidirectional promoter sequences with both pol II and pol III activity, addition of Kozak consensus sequences, termination sequences, addition of conditional pol II/pol III bidirectional promoter expression, addition of a donor template sequence for correcting mutations, or combinations thereof. Other aspects of the invention relate to modifications to Cas9 through post-transcriptional cell-cycle regulation fusions, engineered partial target sites such that the nuclease can bind without DNA cleavage, auto-regulation sites, and N-terminal modifications to modulate half-life.

Abstract: Described herein are methods comprising administering to a mammalian subject an effective amount of an annexin chimeric fusion protein, wherein the annexin chimeric fusion protein comprises at least one immunogenic antigen, thereby enhancing the antigen specific immune response relative to administration of the immunogenic antigen alone. Methods and kits for treating or preventing recurrence of hyper proliferating diseases, e.g., cancer, are described. A method may comprise priming a mammal by administering to the mammal an effective amount of a chemotherapeutic agent and boosting the mammal by administering to the mammal an effective amount of an annexin chimeric fusion.

Abstract: A device may obtain field images of a tissue sample, apply, to the field images, spatial distortion and illumination-based corrections (including corrections for photobleaching of reagents) to derive processed field images, identify, in each processed field image, a primary area including data useful for cell or subcellular component characterization, identify, in the processed field images, areas that overlap with one another, and derive information regarding a spatial mapping of cell(s) and/or sub-cellular components of the tissue sample. Deriving the information may include performing segmentation based on the data included in the primary area of each processed field image, and obtaining flux measurements based on other data included in the overlapping areas.
Abstract: Blockade of immune checkpoints such as cytotoxic T-lymphocyte antigen-4 (CTLA-4) and programmed death-1 (PD-1) shows promise in patients with cancer. Inhibitory antibodies directed at these receptors have been shown to break immune tolerance and promote anti-tumor immunity. These agents work particularly well in patients with a certain category of tumor. Such tumors may be particularly susceptible to treatment because of the multitude of neoantigens which they produce.

Abstract: The present invention describes an integrated apparatus that enables identification of invasive tumor cells directly from a specimen. The methods using the apparatus can be used to prognose or predict the survivability of the cancer in a subject and the risk of recurrence of the cancer in the subject after treatment. The methods disclosed herein can be used to determine which chemotherapeutic or other therapies most strongly inhibit the tumor cells invasiveness as a form of personalized therapy.
