摘要:
The present invention relates to methods of selectively reacting a compound of Formula (I) with a cysteine residue, which is contained in the sequence of a polypeptide. The methods may be employed in the fields of labelling polypeptides, detecting polypeptides, modulation of enzyme activity, isolation of polypeptides, methods of diagnostics, methods of prevention or treatment of clinical conditions or methods of transportation of compounds e.g. prodrugs.

摘要:
The technology relates in part to methods for controlling elimination of therapeutic cells, for example, cells that express a chimeric antigen receptor. The technology further relates to a two-step method of controlling destruction of therapeutic cells in a patient following an adverse event. The two-step system may include a rapamycin or rapamycin analog-based level of control and a second, rimiducid, level of control. The technology also relates in part to methods for cell therapy using cells that express the inducible caspase polypeptide and the rapamycin-sensitive polypeptide, where the proportion of therapeutic cells eliminated by apoptosis is related to the choice and amount of the administered ligand.
摘要:
The present disclosure provides novel compositions and methods suitable for specifically eliminating target cells (e.g., cancer cells) without affecting non-target cells (e.g., non-cancer cells). For example, CRISPR system and the compositions of the present disclosure can be employed to specifically introduce a suicidal gene into a cancer cell in the loci of a cancer-specific target sequence, which as a result of chromosomal re-arrangement or translocation in a cancer cell presents a cancer specific sequence for a guide RNA and CAS to be recognized and such sequence is absent in a non-cancer cell. Consequently, the specific introduction of the composition(s) to cancer-specific site(s) and integration of suicide gene in the target genome, which is inapplicable to normal cells for lack of the site(s), leads to selective elimination of cancer cells but not non-cancer cells, and therefore render novel therapeutic methods and compositions for cancer treatment.
摘要:
The present invention relates to a method for preparing a recombinant Phe-free or Phe- low protein, the method comprising using B.subtilis or B. licheniformis as an expression system and/or a recombinant host cell into which a nucleotide encoding a recombinant Phe-free or Phe-low protein has been inserted into the genome.
摘要:
The present invention provides methods for modulating pluripotency of stem cells and proliferation of cancer cells. The modulation is achieved by promoting dephosphorylation of mRNA-binding protein 3 (RBM3) and down-regulating expression or cellular level of pluripotency factor LIN28. Related methods are provided in the invention for promoting differentiation of stem cells and for inhibiting growth of tumors in subjects. The therapeutic methods of the invention typically entail contacting with a target cell (e.g., a tumor cell) or administering to a subject harboring the target cell a calpain inhibitor and/or an IGF1R inhibitor. Some methods of the invention employ both a calpain inhibitor and an IGF 1R inhibitor.

Some aspects of this disclosure provide strategies, systems, reagents, methods, and kits that are useful for the targeted editing of nucleic acids, including editing a single site within the genome of a cell or subject, e.g. , within the human genome. In some embodiments, fusion proteins of Cas9 and nucleic acid editing enzymes or enzyme domains, e.g. , deaminase domains, are provided. In some embodiments, methods for targeted nucleic acid editing are provided. In some embodiments, reagents and kits for the generation of targeted nucleic acid editing proteins, e.g. , fusion proteins of Cas9 and nucleic acid editing enzymes or domains, are provided.

This document provides methods and materials for treating diabetes. For example, methods and materials for using nucleic acid encoding human preproinsulin to treat diabetes (e.g., type I or type II diabetes) are provided.
摘要:
The present invention relates to means and methods for determining neurotoxin activity. Specifically, it relates to a polypeptide having caspase activity comprising a large subunit and a small subunit wherein said caspase further comprises a neurotoxin cleavage site which upon cleavage activates the caspase activity. Also encompassed are polynucleotides encoding said polypeptides as well as vectors or host cells comprising the polynucleotides. The present invention further relates to a method for determining neurotoxin activity in a sample based on the polypeptide of the invention as well as the use of said polypeptide for determing neurotoxin activity in a sample, in general.
