Methods for enhancing the pluripotency of stem cells

Described herein is the finding that increasing the frequency of Zscan4 activation in mouse ES cells not only enhances, but also maintains their developmental potency in long-term cell culture. As the potency increases, even a whole animal can be produced from a single ES cell injected into a 4N blastocyst at an unexpectedly high success rate. The studies disclosed herein indicate that ES cells acquire higher potency by going through the transient Zscan4 activation state more frequently than the regular state. Particularly disclosed herein is the finding that the constitutive presence of Zscan4-ERT2, even in the absence of its usual activator tamoxifen, can increase the frequency of endogenous Zscan4 activation in ES cells, resulting in the increase of developmental potency of the ES cells. Accordingly, provided herein are Zscan4-ERT2 fusion proteins and nucleic acid molecules and vectors encoding Zscan4-ERT2 fusion proteins. Further provided are methods of prolonging and/or enhancing stem cell pluripotency using the disclosed Zscan4-ERT2 nucleic acid molecules and fusion proteins.

MODEL FOR PREDICTION OF TOLERABILITY ISSUES IN CONNECTION WITH INTRAVENOUS ADMINISTRATION OF THERAPEUTIC ANTIBODIES

The present invention generally relates to combinations for use in therapeutic systems and antibody dosage regimens, and uses thereof. Also described herein is a model for predicting if a therapeutic antibody binding to a human target will be associated with a tolerability issue in connection with intravenous administration and/or for predicting if pre-treatment, altered administration route or modification of the antibody can prevent a tolerability issue associated with intravenous administration to a human of the therapeutic antibody. The model comprises administering the antibody intravenously or intraperitoneally to mice and observing the mice immediately after the administration for any transient display of the macroscopic symptoms isolation and decreased activity. The model may also comprise administration of a pre-treatment in combination with administration of the antibody, administration of the therapeutic antibody by a route of administration other than intravenous or intraperitoneal administration or administration of a modified format of the antibody to mice and observing the mice immediately after such administration for any transient display of the macroscopic symptoms isolation and decreased activity and comparing this with the transient display of the macroscopic symptoms isolation and decreased activity after the intravenous or intraperitoneal administration of the unmodified antibody without pre-treatment.

The disclosure relates to fusion proteins comprising a tBID polypeptide and a steroid hormone receptor domain, and methods of using same to induce apoptosis in cells.

CAS9 PROTEINS INCLUDING LIGAND-DEPENDENT INTEINS

Some aspects of this disclosure provide compositions, methods, systems, and kits for controlling the activity of RNA-programmable endonucleases, such as Cas9, or for controlling the activity of proteins comprising a Cas9 variant fused to a functional effector domain, such as a nuclease, nickase, recombinase, deaminase, transcriptional activator, transcriptional repressor, or epigenetic modifying domain. For example, the inventive proteins provided comprise a ligand-dependent intein, the presence of which inhibits one or more activities of the protein (e.g., gRNA binding, enzymatic activity, target DNA binding). The binding of a ligand to the intein results in self-excision of the intein, restoring the activity of the protein.

NOVEL PEPTIDES AND COMBINATION OF PEPTIDES FOR USE IN IMMUNOTHERAPY AGAINST VARIOUS CANCERS

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.
