Particularly in ER⁺ breast cancer patients, the combination therapy significantly improves treatment efficacy, providing a novel treatment strategy. This invention provides a novel ER⁺... + An integrated approach to breast cancer prognosis assessment and treatment has significant clinical application value.

The application discloses ZmRLR1 application of a gene and a coded protein in regulating corn root development. ZmRLR1 The nucleotide sequence of the gene is shown in the sequence table SEQ ID No: 1, and the protein sequence is shown in the sequence table SEQ ID No: 2. The number of lateral root primordia, the total length of lateral roots and the total lateral root density of the seedling stage of the ZmRLR1 protein overexpression transgenic plant are significantly increased, the number and size of the root system of the fifth layer of crown roots at the mature stage are significantly increased, and the weight of the rhizosphere soil is increased.

The application discloses application of OsHTT6 protein in regulating high-temperature stress tolerance and yield of rice. The application finds that inhibiting expression of the OsHTT6 protein can improve the high-temperature stress tolerance of rice, improve the survival rate of rice seedlings after suffering high-temperature stress, and improve the single-plant yield of rice by constructing an OsHTT6 protein function loss mutant rice strain and an OsHTT6 protein overexpression transgenic rice strain; and overexpression of the OsHTT6 protein can reduce the high-temperature stress tolerance of rice, and reduce the single-plant yield of rice. That is, the high-temperature stress tolerance of rice and the yield of rice can be regulated by regulating expression of the OsHTT6 protein; a reagent capable of inhibiting expression of the OsHTT6 protein can be used to improve the high-temperature stress tolerance and yield of rice, or a heat-resistant and high-yield rice plant can be constructed. The application is favorable for cultivation of heat-resistant and high-yield rice varieties.

The invention relates to a sulfonyl compound and a pharmaceutical composition and application thereof, the sulfonyl compound comprises a compound shown in a formula I, the sulfonyl compound is competitively combined with KAT6A / KAT6B in a binding pocket of KAT6A / KAT6B substrate acetyl coenzyme, the acetyl coenzyme is inhibited from being combined with KAT6A / KAT6B to catalyze histone related sites, gene expression inducing cancer cell growth is prevented, and the cancer cell growth is inhibited. Further, the KAT6A / KAT6B gene can be used for treating related tumor diseases caused by KAT6A / KAT6B gene amplification or KAT6A / KAT6B protein overexpression.

The invention provides a compound shown in a formula (I) or pharmaceutically acceptable salt thereof, and the compound or the pharmaceutically acceptable salt thereof can be used as a KAT6 inhibitor for treating cancers, and is particularly used for treating tumor diseases related to KAT6A / KAT6B gene amplification or KAT6A / KAT6B protein overexpression.

The invention discloses an application of an overexpression agent of a TRIM7 gene and / or a TRIM protein in preparation of an anti-rabies drug. According to the invention, by measuring the expression level of rabies virus structural genes / proteins in cells infected with rabies virus after overexpression of TRIM7 and healthy cells, it is determined that the overexpression agent of TRIM7 gene and / or TRIM protein can be used for resisting rabies, inhibiting the growth of rabies and / or reducing the titer of rabies virus, thereby reducing the proliferation of rabies virus. Therefore, the composition using the product containing the over-expressed TRIM7 gene and / or TRIM7 protein can effectively prevent and / or treat rabies.
