HYBRID NUCLEIC ACID MOLECULES AND THEIR USE

The invention relates to a nucleic acid molecule comprising: a. a first region comprising a nucleic acid sequence coding for the protein Cyclin D1, also called CCND1, said first region being controlled by means allowing the expression of said protein, and b. at least one second region, said second region comprising essentially a sequence from 14 to 59 nucleic acids, said second region corresponding to a transcribed region of a gene, said second region containing at least a genetic modification compared to the same region of the corresponding wild-type version of said gene, said second region being genetically isolated from the means allowing the expression of said protein such that said second region is not translated into a peptide.

Protease inhibitor:protease sensitive expression system and method improving the therapeutic activity and specificity of proteins and phage and phagemids delivered by bacteria
11485773 · 2022-11-01 ·

A genetically engineered live bacterium which is adapted to selectively replicate in and colonize a selected tissue type within the mammal, and concurrently produce within the selected tissue type at least one protease-sensitive cytotoxic molecule which is degradable by proteases within the selected tissue type, and at least one protease inhibitor peptide to inhibit the proteases within the selected tissue type from proteolytically degrading the protease sensitive cytotoxic molecule. The combination results in higher concentrations of the cytotoxic molecule local to the colonization, while permitting protease degradation of the cytotoxic molecule further away from the colonization.

Half of the cancers typically occur due to ineffective capability in their p53 proteins. The invention supplies the cells of the human body or patient with mRNA which will generate effective wild-type p53 proteins, so that this said protein can conduct proper surveillance inside the body's cells and act to destroy cells which have become or are about to become cancerous. The invention also includes introduction of interfering RNA to degrade mutated p53, allowing wild-type p53 proteins to form functional oligomers for cellular surveillance.

GENE-REGULATING COMPOSITIONS AND METHODS FOR IMPROVED IMMUNOTHERAPY

The present disclosure provides methods and compositions related to the modification of immune effector cells to increase therapeutic efficacy. In some embodiments, immune effector cells modified to reduce expression of one or more endogenous target genes, or to reduce one or more functions of an endogenous protein to enhance effector functions of the immune cells are provided. In some embodiments, immune effector cells further modified by introduction of transgenes conferring antigen specificity, such as exogenous T cell receptors (TCRs) or chimeric antigen receptors (CARs) are provided.

PHARMACEUTICAL COMPOSITION CONTAINING HERES EXPRESSION INHIBITOR FOR PREVENTING OR TREATING SQUAMOUS CELL CARCINOMA

The present invention pertains to a pharmaceutical composition for preventing or treating squamous cell carcinoma, the pharmaceutical composition containing a highly expressed lncRNAs in esophageal squamous cell carcinoma (HERES) expression inhibitor. More specifically, the present invention pertains to a pharmaceutical composition which uses a HERES expression inhibitor to reduce the expression of HERES and affect Wnt signaling pathways, and thereby prevent or treat squamous cell carcinoma.

The present inventors discovered that the expression pattern of HERES is related to the onset of squamous cell carcinoma, and found that HERES can be a target for treating squamous cell carcinoma. Accordingly, the pharmaceutical composition according to the present invention was determined to have the effect of inhibiting the proliferation, metastasis, and the like of squamous cell carcinoma by containing the HERES expression inhibitor, and is thus expected to be advantageously used for preventing and treating or ameliorating squamous cell carcinoma.

The present invention relates to the use of an antisense oligonucleotide targeting LINC00518 for the treatment of melanoma.

PHARMACEUTICAL COMPOSITIONS, KITS AND METHODS FOR TREATING TUMORS

Provided is a composition for treating tumors in a subject comprising a therapeutically effective amount of an exosome carrying CTLA4-targeting miRNA and a therapeutically effective amount of an oncolytic herpes simplex virus expressing an immunostimulatory agent or both an immunostimulatory agent and an anti-PD-1 antibody. Wherein an exo-motif operably links to the seed sequence of the CTLA4-targeting miRNA to enhance the packaging of the CTLA4-targeting miRNA into the exosome.

LYMPHOMA CELL-SPECIFIC DRUG DELIVERY SYSTEM FOR PREVENTION OR TREATMENT OF LYMPHOMA AND METHOD FOR PREPARING SAME

Disclosed are a lymphoma cell-specific drug delivery system for the prevention or treatment of lymphoma and a production method therefor. The lymphoma cell-specific drug delivery system may be delivered into lymphoma cells in an improved manner compared to conventional single-target drug delivery systems, and is applicable to the delivery of various therapeutic drugs for the treatment of lymphoma through the application of a wide range of drugs and the same antibody functionalization strategy on the surface of different types of nanoparticles. In addition, the drug delivery system may be introduced into lymphoma as well as other cancer types by adjusting the type and mixing ratio of antibody, and may propose a method of introducing polymeric nucleic acid drugs having superior physiological stability and drug efficacy compared to conventional monomeric nucleic acid drugs, thereby enabling effective drug treatment of lymphoma which is highly resistant to intracellular drug delivery.

TARGETED THERAPY COMPOSITION AND ITS USE FOR SUPPRESSING BREAST CANCER CELL PROLIFERATION, MIGRATION OR INVASION
20230089224 · 2023-03-23 ·

The present invention discloses a targeted therapy composition and a method for suppressing breast cancer cell proliferation, migration or invasion by administrating the targeted therapy composition to a subject in need thereof. The composition comprises a type 3 epithelial membrane proteins (EMP3) targeted inhibitor. The breast cancer cells are characterized by upregulation of EMP3, EGFR, HER2, HER3, HR, or downregulation of HER4 gene expression. EMP3-targeting oligonucleotide or nuclease is administrated upon the breast cancer cells so as to degrade EMP3-coding DNA or mRNA, and to suppress breast cancer cell proliferation, migration or invasion.
