The present invention relates to a method for identifying a cell (group), a method comprising a cell stratifying process utilizing quantitative physical property data, a method for separating a cell (group) utilizing the cell stratifying process, a method for identifying a molecular marker that identifies a cell (group) utilizing the cell stratifying process, a method for culturing a cell (group) utilizing the cell stratifying process, a program for causing a computer to execute a step of identifying a cell (group) utilizing the cell stratifying process, and a system for analyzing, identifying, or separating a cell (group) utilizing the cell stratifying process.

An isolated Methyl-CpG binding domain (MBD) variant may include an MBD core domain having at least 60% sequence homology relative to any one of SEQ ID Nos. 1-45 and comprising at least one amino acid substitution relative to the corresponding wildtype MBD in various positions. The isolated MBD variant or the conjugate may be used for determining the methylation state of cytosine residues and/or oxidation state of 5-methylated cytosine residues in a CpG dinucleotide of interest and its complement in a DNA molecule or for the enrichment of DNA molecules comprising a CpG dinucleotide of interest and its complement. At least one cytosine nucleobase in the CpG dinucleotide may be modified to be 5-methylcytosine (mC), 5-hydroxymethylcytosine (hmC), 5-formylcytosine (fC), or 5-carboxylcytosine (caC).

The disclosure provides a method for producing hepatocytes or hepatic progenitor cells; a method for suppressing hepatocyte aging using a drug causing histone hyperacetylation; a hepatocyte anti-aging agent; a method for increasing hepatocyte plasticity; and a drug for increasing hepatocyte plasticity.

Provided is a host factor specific for hepatitis B virus (HBV) infection. The specific host factor CREBH can remarkably enhance HBV infection. The specific host factor can, on the one hand, enhance entry of HBV, and on the other hand, enhance transcription of HBV to some extent. In the CREBH regulatory pathway there is a specific host factor SCARF2. During HBV infection, an N-terminus EGF-like domain of SCARF2 plays a crucial role in the infection and entry of HBV. The two correlated specific host factors provide a new target for inhibiting HBV infection.

The object of the invention is to provide a method for easily and objectively detecting mood disorders in a subject by measuring the expression levels of prescribed genes in the peripheral blood of the subject, the reliability of the detection result being high. The invention also provides a method for detecting mood disorders in a subject, the method having a step for measuring the gene expression levels of ribosomal protein genes, CDKN1C, or any combination thereof in the peripheral blood derived from the subject, and detecting whether or not the subject has mood disorders on the basis of the measurement results.

Kits and methods for detecting pathogens without the need for laboratory equipment are disclosed. The kits and methods described herein allow for near-room temperature amplification of pathogen polynucleotides in a biological sample in a one-compartment reaction vessel. The kits and methods may be used to detect any target nucleic acid, such as DNA or RNA from a bacterial, fungal, or viral pathogen.
