    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 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.

    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.
