    GO:0046697    decidualization    The cellular and vascular changes occurring in the endometrium of the pregnant uterus just after the onset of blastocyst implantation. This process involves the proliferation and differentiation of the fibroblast-like endometrial stromal cells into large, polyploid decidual cells that eventually form the maternal component of the placenta.
    GO:0050892    intestinal absorption    Any process in which nutrients are taken up from the contents of the intestine.
    GO:0007595    lactation    The regulated release of milk from the mammary glands and the period of time that a mother lactates to feed her young.
    GO:0060745    mammary gland branching involved in pregnancy    The process in which the branching structure of the mammary gland duct is generated and organized as a part of pregnancy.
    GO:0007275    multicellular organism development    The biological process whose specific outcome is the progression of a multicellular organism over time from an initial condition (e.g. a zygote or a young adult) to a later condition (e.g. a multicellular animal or an aged adult).
    GO:0008285    negative regulation of cell proliferation    Any process that stops, prevents or reduces the rate or extent of cell proliferation.
    GO:0010839    negative regulation of keratinocyte proliferation    Any process that decreases the rate, frequency or extent of keratinocyte proliferation. Keratinocyte proliferation is the multiplication or reproduction of keratinocytes, resulting in the expansion of a cell population.
    GO:0000122    negative regulation of transcription from RNA polymerase II promoter    Any process that stops, prevents, or reduces the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0045892    negative regulation of transcription, DNA-templated    Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0060058    positive regulation of apoptotic process involved in mammary gland involution    Any process that activates or increases the frequency, rate or extent of cell death by apoptotic process of mammary epithelial cells during mammary gland involution.
    GO:0010628    positive regulation of gene expression    Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.
    GO:0045618    positive regulation of keratinocyte differentiation    Any process that activates or increases the frequency, rate or extent of keratinocyte differentiation.
    GO:0045944    positive regulation of transcription from RNA polymerase II promoter    Any process that activates or increases the frequency, rate or extent of transcription from an RNA polymerase II promoter.
    GO:0010980    positive regulation of vitamin D 24-hydroxylase activity    Any process that increases the rate, frequency or extent of vitamin D 24-hydroxylase activity. Vitamin D 24-hydroxylase activity catalyzes the hydroxylation of C-24 of any form of vitamin D.
    GO:0060558    regulation of calcidiol 1-monooxygenase activity    Any process that modulates the rate, frequency or extent of calcidiol 1-monooxygenase activity. Calcidiol 1-monooxygenase activity is catalysis of the reaction: calcidiol + NADPH + H+ + O2 = calcitriol + NADP+ + H2O.
    GO:0006355    regulation of transcription, DNA-templated    Any process that modulates the frequency, rate or extent of cellular DNA-templated transcription.
    GO:0007165    signal transduction    The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.
    GO:0001501    skeletal system development    The process whose specific outcome is the progression of the skeleton over time, from its formation to the mature structure. The skeleton is the bony framework of the body in vertebrates (endoskeleton) or the hard outer envelope of insects (exoskeleton or dermoskeleton).
    GO:0043401    steroid hormone mediated signaling pathway    A series of molecular signals mediated by a steroid hormone binding to a receptor.
    GO:0006367    transcription initiation from RNA polymerase II promoter    Any process involved in the assembly of the RNA polymerase II preinitiation complex (PIC) at an RNA polymerase II promoter region of a DNA template, resulting in the subsequent synthesis of RNA from that promoter. The initiation phase includes PIC assembly and the formation of the first few bonds in the RNA chain, including abortive initiation, which occurs when the first few nucleotides are repeatedly synthesized and then released. Promoter clearance, or release, is the transition between the initiation and elongation phases of transcription.
    GO:0006351    transcription, DNA-templated    The cellular synthesis of RNA on a template of DNA.
    GO:0070561    vitamin D receptor signaling pathway    The series of molecular signals generated as a consequence of a vitamin D receptor binding to one of its physiological ligands.
cellular component
    GO:0090575    RNA polymerase II transcription factor complex    A transcription factor complex that acts at promoters of genes transcribed by RNA polymerase II.
    GO:0005654    nucleoplasm    That part of the nuclear content other than the chromosomes or the nucleolus.
    GO:0005634    nucleus    A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.
    GO:0043235    receptor complex    Any protein complex that undergoes combination with a hormone, neurotransmitter, drug or intracellular messenger to initiate a change in cell function.
