Abstract: The disclosure relates to methods for determining an endometrial status using a sample, for example, an endometrial biopsy, from a woman, comprising: (a) performing an assay on the endometrial sample from the woman to determine a microRNA (miRNA) expression profile of the endometrial sample, wherein the miRNA expression profile comprises expression levels of a plurality of miRNAs, for example, 167 miRNAs having the sequences of SEQ ID NOs:1-167, respectively; and (b) analyzing the miRNA expression profile to obtain a receptivity predictive score using, for example, a computer-based algorithm. Aspects of the disclosure further relate to kits suitable for performing the methods, as well as uses of the kits for diagnostic and therapeutic purposes.

Abstract: The invention provides a cancer early detection method using liquid biopsy, the cancer early detection method includes the following steps. MicroRNA expression profile database of cancer patient populations and healthy populations are established. Afterwards, an analysis model for cancer early detection is established through the following steps: a data quality control, a technical replicate merging, a calculation of normalization factors and data normalization, a biomarker feature selection, and a hyperparameter tuning. The analysis model for cancer early detection includes normalization factors, a set of biomarkers, model weights and model hyperparameters. A microRNA expression profile in a liquid biopsy sample of a subject is analyzed by the analysis model for cancer early detection to be used as a basis for an early detection of cancer.

Abstract: An early detection and prediction method of pan-cancer is provided, including the following steps. A microRNA expression profile database of cancer patient populations and healthy populations is established, and an early detection and prediction method of pan-cancer is developed based on the microRNA expression profile database. Next, a microRNA expression profile of a liquid biopsy sample of a subject is analyzed via the early detection and prediction method of pan-cancer, so as to determine whether the subject may already have cancer.

Abstract: The disclosure provides a health risk assessment method including the following steps. A miRNA expression database of a healthy population is established. A miRNA expression in a plasma specimen of a subject is analyzed. After that, miRNA expression data of the subject is compared with the miRNA expression in the miRNA expression database of the healthy population, and the miRNA expression being too high or too low in the plasma specimen of the subject is found out to assess health risk of the subject.

Abstract: The present invention provides an expression vector comprising an internal ribosome entry site (IRES) element, comprising a sequence of SEQ ID NO: 1, wherein the sequence is an IRES element from a gene icp35 of White spot syndrome virus. The expression vector can be easily operated in insect cells or Crustacean cells and has excellent expression efficiency due to having such an IRES element. A multiple expression gene system is also provided herein, which comprises the expression vector. The system comprising the IRES element can be functioned via transfection, such that the experimental process can be considerably shortened, and thus studying costs will be reduced effectively.
