Lipids Part 2: Steroids
 
04:45
Steroids have gotten a pretty bad rap! In reality, they're not just the big bad anabolic steroids. This class of molecules includes many vitamins as well as cholesterol. Cholesterol has also gotten a bad rap! We need cholesterol for our cell membranes to be rigid enough to stay intact, and for our bodies to build other important molecules. What I'm saying is that you should watch all of these tutorials, and don't believe everything you hear around town about molecules!

Steroid hormone receptors
 
06:05
Nuclear receptors Main article: nuclear receptor Steroid receptors of the nuclear receptor family are all transcription factors. Depending upon the type of receptor, they are either located in the cytosol and move to the cell nucleus upon activation, or remain in the nucleus waiting for the steroid hormone to enter and activate them. This uptake into the nucleus is facilitated by nuclear localization signal (NLS) found in the hinge region of the receptor. This region of the receptor is covered up by heat shock proteins (HSPs) which bind the receptor until the hormone is present. Upon binding by the hormone the receptor undergoes a conformational change releasing the HSP, and the receptor together with the bound hormone enter the nucleus to act upon transcription. Nuclear receptors Subfamily 3: Estrogen Receptor-like Group A: Estrogen receptor (Sex hormones: Estrogen) 1: Estrogen receptor-α (ERα; NR3A1, ESR1) 2: Estrogen receptor-β (ERβ; NR3A2, ESR2) Group C: 3-Ketosteroid receptors 1: Glucocorticoid receptor (GR; NR3C1) (Cortisol) 2: Mineralocorticoid receptor (MR; NR3C2) (Aldosterone) 3: Progesterone receptor (PR; NR3C3, PGR) (Sex hormones: Progesterone) 4: Androgen receptor (AR; NR3C4, AR) (Sex hormones: Testosterone) Structure Intracellular steroid hormone receptors share a common structure of four units that are functionally homologous, so-called "domains": Variable domain: It begins at the N-terminal and is the most variable domain between the different receptors. DNA binding domain: This centrally located highly conserved DNA binding domain (DBD) consists of two non-repetitive globular motifs[3] where zinc is coordinated with four cysteine and no histidine residues. Their secondary and tertiary structure is distinct from that of classic zinc fingers.[4] This region controls which gene will be activated. On DNA it interacts with the hormone response element (HRE). Hinge region: This area controls the movement of the receptor to the nucleus. Hormone binding domain: The moderately conserved ligand-binding domain (LBD) can include a nuclear localization signal, amino-acid sequences capable of binding chaperones and parts of dimerization interfaces. Such receptors are closely related to chaperones (namely heat shock proteins hsp90 and hsp56), which are required to maintain their inactive (but receptive) cytoplasmic conformation. At the end of this domain is the C-terminal. The terminal connects the molecule to its pair in the homodimer or heterodimer. It may affect the magnitude of the response. Mechanism of action Genomic Depending on their mechanism of action and subcellular distribution, nuclear receptors may be classified into at least two classes.[5][6] Nuclear receptors that bind steroid hormones are all classified as type I receptors. Only type I receptors have a heat shock protein (HSP) associated with the inactive receptor that will be released when the receptor interacts with the ligand. Type I receptors may be found in homodimer or heterodimer forms. Type II nuclear receptors have no HSP, and in contrast to the classical type I receptor are located in the cell nucleus. Free (that is, unbound) steroids enter the cell cytoplasm and interact with their receptor. In this process heat shock protein is dissociated, and the activated receptor-ligand complex is translocated into the nucleus. After binding to the ligand (steroid hormone), steroid receptors often form dimers. In the nucleus, the complex acts as a transcription factor, augmenting or suppressing transcription particular genes by its action on DNA. Type II receptors are located in the nucleus. Thus, their ligands pass through the cell membrane and cytoplasm and enter the nucleus where they activate the receptor without release of HSP. The activated receptor interacts with the hormone response element and the transcription process is initiated as with type I receptors. Non-genomic .

Mechanism of STEROID HORMONE action
 
01:27
Mechanism of STEROID HORMONE action : Receptors for steroid and thyroid hormones are located inside target cells, in the cytoplasm or nucleus, and function as ligand-dependent transcription factors. That is to say, the hormone-receptor complex binds to promoter regions of responsive genes and stimulate or sometimes inhibit transcription from those genes.

We consider Student needs, Lecturer needs and College needs in designing the 3D & 2D Animated Video Lectures. We are carrying a huge 3D Digital Library ready to use. MECHANISM OF HORMONE ACTION :Hormones produce their effects on target tissues by binding to specific proteins called hormone receptors located in the target tissues only. Hormone receptors present on the cell membrane of the target cells are called membrane bound receptors and the receptors present inside the target cell are called intercellular receptors, mostly nuclear receptors. Binding of a hormone to its receptors leads to the formation of a hormone receptor complex. Each receptor is specific to one hormone only and hence receptors are specific. Hormone – Receptor complex formation leads to certain biochemical changes in the target tissue. Target tissue metabolism and hence physiological functions are regulated by hormones can be divided into groups.Peptide, polypeptide, protein hormones insulin, glucagon, pituitary hormones, hypothalamic hormones etc Steroids cortisol, testosterone, estradiol and progesteroneIodohyronines – thyroid hormones.Amino acid derivative – epinephrine.Hormones which interact with membrane bound receptors normally do not enter the target cell, but generate second messengers.eg. Cyclic AMP, Ip3, Ca++ etc which in turn regulate cellular metabolism.Hormones which interact with intra cellular receptors (steroid hormones, iodothyronines etc). mostly regulate gene expression or chromosome function by the interaction of hormone – receptor complex with genome. Cumulative biochemical actions result in physiological and development effects.

Steroid vs. Peptide Hormones: CGI Animation
 
02:31
A super simple and somewhat cheesy (unfortunately) CGI animation I made which illustrates the difference between steroid and peptide hormones. Great for educational purposes if teachers want to give lectures side by side explaining each part of the animation. I only had two hours to make this entire animation, so it is a bit badly made, but for only two hours of work, there’s only so much you can do. Sorry :( If I’d had more time, I would have tried to get it to not look as cheesy as it does (although I’m not sure how much I would be able to improve it from its current state with my limited knowledge of Element) and create my own soundtrack for it, as I usually do in a video like this. However, being on a strict time frame of just two hours, this was probably the best I could do. Why two hours, you ask? Because it was for a chemistry project that I had to present the next day. And I hadn’t put the presentation together yet. I ended up not even using this animation for the presentation, but it still went relatively well. I had a little bit of fun throwing in that universal leader at the beginning ;) One of the many hidden features of Premiere Pro. (Well, okay, maybe it's not *hidden*, but...)

 Cynthia Miller. How Hormones Use G-protein Signaling Pathways: A Video Review of the Basics. APS Archive of Teaching Resources, http:--www.apsarchive.org-resource.cfm?submissionID=6715 August 1, 2012. Description: G-protein signaling cascades can be difficult for students to visualize, and even more challenging to integrate with physiological concepts. This Camtasia video was designed to reinforce the basics of how the endocrine system uses two particular G-proteins: Gs and Gq. Animations were created in order to explain how hormones can lead to temporary increases in intracellular cAMP and calcium levels.

What is STEROID HORMONE? What does STEROID HORMONE mean? STEROID HORMONE meaning - STEROID HORMONE definition - STEROID HORMONE explanation. Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/by-sa/3.0/ license. A steroid hormone is a steroid that acts as a hormone. Steroid hormones can be grouped into 2 classes, corticosteroids (typically made in the adrenal cortex, hence cortico-) and sex steroids (typically made in the gonads or placenta). Within those 2 classes are 5 types according to the receptors to which they bind: glucocorticoids and mineralocorticoids (corticosteroids) and androgens, estrogens, and progestogens (sex steroids). Vitamin D derivatives are a sixth closely related hormone system with homologous receptors. They have some of the characteristics of true steroids as receptor ligands. Steroid hormones help control metabolism, inflammation, immune functions, salt and water balance, development of sexual characteristics, and the ability to withstand illness and injury. The term steroid describes both hormones produced by the body and artificially produced medications that duplicate the action for the naturally occurring steroids.
