Details for anatomical structure: sebaceous glands

EndoNet ID: ENC00212

To link to the content of EndoNet use the EndoNet ID that is given on the detail pages in the format ENX0000, where X is a place holder for the type of the component (e. g. R for receptor or C for anatomical structure).
As URL for the linking append this ID to the detail page for this type of component.
For an hormone that would be:

http://endonet.bioinf.med.uni-goettingen.de/hormone/ENH00000

It is also possible to use the search of EndoNet to link to the right detail page. The URL should look like

If the search pattern is unambigious the user is directed to the corresponding detail page.

Synonyms

sebaceous glands, oil glands, sebaceous follicles, Glandulae sebaceae

General information

Numerous holocrine glands in the dermis that usually open into the hair follicles and secrete an oily semifluid sebum

    Substructures

      Secreted hormones

      • Hormone: CST6

        • Cystatin M/E is constitutively expressed in the stratum granulosum of normal skin, sebaceous glands, eccrine sweat glands and the infundibular epithelium of hair follicles. [1]

      Receptors

      • Receptor: ER-alpha

        Induced phenotype:

        • sebaceous gland development
          • Systematically administered estrogen elicits a reduction in the size and secretion of sebaceous glands both in men and women, but this effect is usually achieved only with doses that exceed the physiologic requirement of women and produce feminization in men. [2]
      • Receptor: ER-beta

        Induced phenotype:

        • sebaceous gland development
          • Systematically administered estrogen elicits a reduction in the size and secretion of sebaceous glands both in men and women, but this effect is usually achieved only with doses that exceed the physiologic requirement of women and produce feminization in men. [2]
      • Receptor: PR B

        Induced phenotype:

        • sebaceous gland development
          • Progesterone could increase the size of sebaceous glands in spayed rats. [3]
          • But this hormone is not responsible for maintaining sebaceous gland secretion. [2]
      • Receptor: progesterone receptor A

        Induced phenotype:

        • sebaceous gland development
          • Progesterone could increase the size of sebaceous glands in spayed rats. [3]
          • But this hormone is not responsible for maintaining sebaceous gland secretion. [2]
      • Receptor: AR

        Induced phenotype:

        • sebaceous gland development
          • The development of the sebaceous gland depends on androgens. The administration of testosterone to castrated males, children or postmenopausal women in whom sebaceous secretion is normally low results in significant increase in sebaceous gland activity. Thus, the sebaqueous gland is an androgen target-organ. [2]
      • Receptor: CRF-R1

      • Receptor: melanocortin receptor 5

        Induced phenotype:

        • sebogenesis
          • Since sebaceous glands of mice dereived from skin express MC5-R and targeted disruption of it results in reduced water repulsion and sebum secretion, it is possible that MC5-R in man likewise mediates sebogenesis. [4]
        • sebaceous gland development
          • Adrenal androgens may contribute significantly in sebaceous gland development. If neither estrogen nor ACTH has any directly supressive or stimulating effect respectively on the sebaqueous gland, the negative response to ACTH stimulation may mean either that endogenous androgens from the adrenal cortex are not sebum stimulating or that the estrogen together with pituitary-gonadal hormones supresses the adrenal gland directly.
