The present invention provides for novel methods for regulating and detecting the cytosine methylation status of DNA. The invention is based upon identification of a novel and surprising catalytic activity for the family of TET proteins, namely TET1, TET2, TET3, and CXXC4. The novel activity is related to the enzymes being capable of converting the cytosine nucleotide 5-methylcytosine into 5-hydroxymethylcytosine by hydroxylation.

The present invention provides methods and kits for differentiating podocytes from pluripotent stem cells and from other cell types.

Methods and compositions, including nucleotide sequences, amino acid sequences, and host cells, for producing fatty alcohols are described.

The present invention provides methods for delivering a transient and/or reversible complex into a cell including passing a cell suspension through a constriction, wherein said constriction deforms the cell, thereby causing a perturbation of the cell such that the complex enters the cell.

The present invention provides, in some embodiments, methods of promoting an immune response in a subject in need thereof, comprising administering to a subject a population of immune cells that express an exogenous enzyme that facilitates immune cell function in a nutrient-poor environment. Other embodiments of the invention include methods of promoting an immune response to a tumor in a subject in need thereof, comprising administering to the subject an effective amount of an agent that provides a one-carbon unit (e.g., formate) and an agent that promotes an anti-tumor response, and methods of promoting an immune response to a tumor in a subject in need thereof, comprising administering to a subject an effective amount of an agent that inhibits consumption of metabolic fuels by tumor cells. The invention also provides, in other embodiments, compositions comprising an ex vivo population of immune cells expressing an exogenous enzyme that enhances immune cell function in nutrient poor environments, and compositions comprising a nucleic acid expression construct encoding an inhibitor of glucose metabolism, and a pharmaceutically acceptable carrier or excipient.

The present invention is related to a medium additive composition comprising peroxidasin for serum-free cell culture, and a method of performing serum-free culture of cells by using the same.

The present invention is related to a cell culture medium for the expression of a protein, which medium comprises a PAM inhibitor, or a physiological equivalent thereof, and to a cell culture process for the expression of a protein, in which process a PAM inhibitor, or a physiological equivalent thereof, is used (FIG. 1).
