The invention belongs to the technical field of medicines, and discloses a KRT6A gene expression inhibitor and application thereof in preparation of a medicine for treating gemcitabine drug-resistant pancreatic cancer. Researches find that KRT6A is abnormally highly expressed in pancreatic cancer and is closely related to poor curative effect of gemcitabine. According to the inhibitor, KRT6A gene expression is specifically silenced in a tumor targeted delivery mode, expression and functions of nucleoside transporter ENT1 are recovered, and cellular uptake of gemcitabine is enhanced; the compound can inhibit MIF-CD44 / CD74 signal axis mediated tumor-associated macrophage M2 type polarization, reduce exogenous pyrimidine nucleoside supply and weaken competitive inhibition of the compound and gemcitabine in nucleoside transport and metabolic pathways, so that effective uptake and efficacy of gemcitabine in pancreatic cancer cells are synergistically improved, and gemcitabine drug resistance is reversed or relieved. The invention provides a new and effective technical scheme for clinical treatment of gemcitabine drug-resistant pancreatic cancer.

The invention belongs to the field of molecular targeted therapy, and discloses a small-molecule inhibitor CTPI3 of a targeted mitochondrial citric acid transporter SLC25A1 and application of the small-molecule inhibitor CTPI3 in tumor therapy. On the basis of an existing inhibitor CTPI2 structure, molecular design is carried out through an induced fit docking (IFD) module of Schrdinger software, and CTPI3 is obtained. Experiments show that the median inhibitory concentration (IC50) of CTPI3 on acute myelogenous leukemia (AML) cell lines (such as Kasumi-1 and THP1) and primary AML cells is obviously lower than that of CTPI2, the synergistic effect of CTPI3 and Venetoclax is enhanced, the mitochondrial ATP yield is reduced, and the TCA cycle metabolite level is affected. Animal experiments prove that CTPI3 can significantly prolong the lifetime of AML model mice and reduce leukemia load (spleen weight is reduced, and bone marrow and peripheral blood GFPcells are reduced), and has no significant toxicity (liver, kidney and brain histopathology is normal). The invention provides an efficient and safe new candidate drug for SLC25A1 targeted therapy.

The application discloses a ricin toxin detection sensor based on competitive binding of ricin to mitochondrial adenine nucleotide translocator (ANT) and a detection method, which comprises ANT protein, hollow dialysis fiber, chemical cross-linking agent and fluorescently labeled ATP. When in use, the ANT is first fixed on the inner wall of the hollow fiber dialysis membrane and the fluorescently labeled ATP (cy5-12-ATP or cy3-12-ATP or DEPC-12-ATP) is added; then, it is placed in the to-be-detected solution for 30-60 seconds, and then is placed under a fluorescence detection instrument (such as a fluorescence microscope) for observation, so that the presence or absence of the ricin toxin and the approximate concentration of the toxin are determined; then, the relative intensity of the fluorescence of the to-be-detected solution is determined; a standard curve of the corresponding relationship between the concentration of the fluorescent group and the concentration of the toxin is established; and the concentration of the ricin toxin in the to-be-detected solution is obtained by substituting the concentration of the fluorescent group of the to-be-detected solution into the above standard curve and performing calculation. The application can effectively improve the detection efficiency, simplify the detection method and be widely applied in the society.

Hepcidin is an hyposideremic hormone made primarily by the liver. To address the role of hepcidin made specifically by the intestine in lowering serum iron, the inventors generated transgenic mice overexpressing the peptide specifically in this tissue. These mice exhibit, at one month of age, a severe hyposideremia, along with decreased haematological indices and hair loss. Mechanistically, they showed that intestinal hepcidin made by the transgenic mice had no effect on intestinal ferroportin, but, in contrast, induced a striking down-regulation of Divalent Metal Transporter 1 (DMT1) protein at the apical side of the enterocyte. Intestinal hepcidin can be produced in the apical side suggesting the direct role of apical hepcidin on DMT1. To confirm the therapeutic capacity of hepcidin on regulation of DMT1, the inventors developed probiotics (engineered recombinant lactic acid bacteria), capable of delivering hepcidin directly into the lumen of the intestine. They orally administrated daily these probiotics in hemochromatosis mice model, after 28 days of treatments they observe a decrease of iron overload. Thus, the present invention relates to a method for preventing or treating an iron overload associated disease in a subject in need thereof, comprising administering locally in the gut of the subject hepcidin.

Research finds that SLC25A22 promotes utilization of glutamic acid in MN9D cell mitochondria, synthesis of alpha-ketoglutaric acid and TCA circulation, and improves generation reduction of ATP in MN9D cells induced by MPP +, ROS accumulation and mitochondrial membrane potential decline, so that damage of MN9D cell activity is relieved, and finally loss of dopaminergic neurons is rescued.
