摘要:
The invention provides a method of selecting a mutant polypeptide having lysine demodification, in particular lysine deacylation, activity, wherein the method comprises the following steps (a) incubating a mutant polypeptide having an amino acid sequence with at least 80% sequence identity to SEQ ID NO: 1 with a peptide or polypeptide comprising an inactivated essential lysine residue; and (b) determining the activity of the mutant polypeptide to activate the peptide or polypeptide comprising the inactivated essential lysine residue, wherein the mutant polypeptide and the peptide or polypeptide comprising an inactivated essential lysine residue are incubated in a biological cell. The invention furthermore relates to an acylated luciferase, particularly Firefly luciferase, and uses thereof. The present invention furthermore relates to a mutant polypeptide comprising an amino acid sequence having at least 98% sequence homology with SEQ ID NOs: 2, 3, 4, 5 or 6 and having lysine demodification, in particular lysine deacylation, activity, wherein the mutant polypeptide is not identical to SEQ ID NO: 1. The invention also relates to the mutant polypeptide of the invention and a peptide or polypeptide comprising an inactivated essential lysine residue for use in treating cancer.
摘要:
Described are methods of inhibiting neurodegeneration in a subject by administering to the subject an agent that prevents (alpha)-syn PFF from binding to its receptor. The agent may be a small molecule chemical compound, antibody, nucleic acid molecule, or polypeptide. Drug screening methods are also provided.
摘要:
A method for measuring autophagosome flux is provided. The autophagosome pool size in a single cell is quantified, where the pool size is the total number of autophagosomes in the cell. Fusion between the autophagosomes and lysosomes in the cell is then inhibited. The autophagosome pool size is quantified over one or more time points after fusion has been inhibited, and the autophagosome flux is calculated as the initial rate of change of the autophagosome pool size at the time point after fusion has been inhibited. The method can be used to determine basal autophagosome flux, whether a cell is diseased or dysfunctional, or to diagnose a subject with a disease, disorder or dysfunction. The transition time, the time required to clear an autophagosome pool, can also be derived from the autophagosome flux. A molecule can also be characterized according to its ability to modulate autophagosome flux in a cell.

The present invention relates to novel peptides derived from Bromodomain testis-specific protein (BRDT), complexes comprising such peptides bound to recombinant MHC molecules, and cells presenting said peptide in complex with MHC molecules. Also provided by the present invention are binding moieties that bind to the peptides and/or complexes of the invention. Such moieties are useful for the development of immunotherapeutic reagents for the treatment of diseases such as cancer.
摘要:
The present invention relates to novel compounds, their uses as biomarker, and/or methods including a non-invasive in vitro method using this biomarker, for diagnosing or monitoring the development or the progression of Alzheimer's disease (AD) or a disease or disorder associated with β-amyloid peptide (Aβ) deposition or tau hyperphosphorylation or a disease or disorder characterized by a proteinopathy implicating abnormalities in protein kinase C (PKC).
摘要:
The invention relates to compounds and methods for restoring or preserving cholesterol efflux in a cell infected with Human Immunodeficiency Virus (HIV) by preventing or decreasing an interaction between Negative Regulatory Factor (Nef) protein and Calnexin protein, and methods for screening for such compounds.
摘要:
It has been demonstrated that certain compounds bind to TNF and stabilise a conformation of trimeric TNF that binds to the TNF receptor. Antibodies which selectively bind to complexes of such compounds with TNF superfamily members are disclosed. These antibodies may be used to detect further compounds with the same activity, and as target engagement biomarker.
摘要:
Procedimiento para identificar inhibidores de la interacción del receptor CD36 y la proteína Αβ (beta- amiloide) que consiste en inmovilizar CD36 en una placa de poliestireno y detectar por colorimetría su interacción con ίΑβ (fibrilla), utilizando un anticuerpo policlonal anti Αβ y un anticuerpo secundario conjugado a peroxidasa de rábano (HRP). Los inhibidores identificados, son agentes potenciales para el tratamiento de la enfermedad de Alzheimer.
摘要:
The present application relates to materials and methods for exploiting synthetic lethality and/or chemo-sensitisation in DNA damage response (DDR) pathways. In particular, the application relates to ubiquitin hydrolase protein Ubiquitin Specific Protease 4 (USP4) and its association with DDR pathways. Further, the use of USP4 inhibitors in the treatment of cancer and methods of screening is described, in particular, use of inhibitors of USP4 in the treatment of tumours defective in double-strand break repair (DSBR) and/or tumours resistant to platinum-based chemotherapy, or to sensitise, i.e. chemosensitise or radiosensitise tumours to other therapeutic agents.
