Regulation of Gene Expression: Operons, Epigenetics, and Transcription Factors
 
13:07
We learned about gene expression in biochemistry, which is comprised of transcription and translation, and referred to as the "central dogma" of molecular biology. But how is this process regulated? How does a cell know which genes to express and when? Well it's pretty complicated, but let's just get our feet wet by looking at operons, epigenetics, and transcription factors!

Like us on Facebook: https://www.facebook.com/pages/Stroma-Studios/290868104261105?sk=wall Each cell in our body inherits the same master copy of DNA, but different cell types use it differently. Transcription Factors help influence which genes are used in which cell. Understanding how these dynamic proteins physically interact with DNA allows us to better understand and model their binding to DNA and their regulation of gene expression.

NDSU Virtual Cell Animations Project animation "Regulated Transcription". For more information please see http://vcell.ndsu.edu/animations. Gene expression is controlled in many different ways. When proteins from outside a cell signal for a specific gene to be transcribed, it is known as regulated transcription. This animation illustrates how a protein like insulin can trigger a regulated transcription event, in addition to setting off the signal pathway illustrated in our Insulin Signaling video.

Transcription Factors & Promoter Region. This is a teaser video. Watch the complete lecture in the member's area at https://www.DrNajeebLectures.com Transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence. In genetics, a promoter is a region of DNA that initiates transcription of a particular gene. Promoters are located near the transcription start sites of genes, on the same strand and upstream on the DNA (towards the 3' region of the anti-sense strand). Promoters can be about 100–1000 base pairs long. ─────────────── DR. NAJEEB LECTURES ─────────────── Dr. Najeeb Lectures are the World's Most Popular Medical Lectures.

Gene regulation in eukaryotes
 
10:39
Gene regulation in eukaryotes - This lecture explains about the eukaryotic gene regulation. Regulation of gene expression entails a vast variety of mechanisms which can be utilized by cells to expand or shrink the creation of particular gene products (protein or RNA), and is informally termed gene legislation. Subtle packages of gene expression are greatly found in biology, for illustration to set off developmental pathways, reply to environmental stimuli, or adapt to new food sources. Virtually any step of gene expression can also be modulated, from transcriptional initiation, to RNA processing, and to the post-translational change of a protein. Gene regulation is main for viruses, prokaryotes and eukaryotes because it raises the flexibility and adaptability of an organism via permitting the cellphone to specific protein when needed. Although as early as 1951 Barbara McClintock confirmed interaction between two genetic loci, Activator (Ac) and Dissociator (Ds), in the color formation of maize seeds, the first discovery of a gene law approach is widely regarded to be the identification in 1961 of the lac operon, learned through Jacques Monod, in which some enzymes involved in lactose metabolism are expressed by using the genome of E. Coli handiest within the presence of lactose and absence of glucose. Furthermore, in multicellular organisms, gene regulation drives the processes of cellular differentiation and morphogenesis, main to the creation of unique cellphone forms that possess different gene expression profiles, and therefore produce one of a kind proteins/have special ultrastructures that suit them to their capabilities (although they all possess the genotype, which follows the equal genome sequence). The initiating event main to a transformation in gene expression include activation or deactivation of receptors. Additionally, there's proof that alterations in a mobile's option of catabolism results in altered gene expressions.

ChEA3: Transcription Factor Enrichment Analysis
 
06:08
Transcription factors (TFs) are proteins that control gene expression by binding and unbinding near coding regions to regulate the transcriptional machinery. TF enrichment analysis (TFEA) prioritizes transcription factors based the overlap between given lists of differentially expressed genes, and previously annotated TF targets assembled from multiple resources. Hence, TFEA can aid in identifying the TFs responsible for observed changes in gene expression when comparing control and perturbation samples. In the past, we have developed and published ChEA and ChEA2 which are ChIP-seq enrichment analysis tools made of gene set libraries created from published ChIP-seq data extracted from multiple sources. ChEA3 builds upon these prior versions of ChEA by including more libraries, adding benchmarks, and cross library analyses. For ChEA3 the following TF-target gene set libraries were assembled: Putative targets as determined by ChIP-seq experiments from ENCODE and individual publications; co-expression of TFs with other genes based on processed RNA-seq from GTEx and ARCHS4; co-occurrence of TFs with other genes by examining thousands of gene lists submitted to the tool Enrichr; protein-protein interactions involving direct interactions with TFs; and gene signatures resulting from single TF perturbations followed by genome-wide gene expression experiments. ChEA3 is delivered as a web-based application that performs TFEA for each TF library individually, and also by integrating the results across all libraries. Using various benchmarks, we found that integrating libraries boosts performance of ranking TF correctly. The ChEA3 web portal application front-end was developed with Mobirise, while the back-end was implemented as two R packages hosted on an OpenCPU server to enable integration via an API. The ChEA3 web application features interactive visualization of a global mammalian TF-TF regulatory network, in which enriched TFs are highlighted as nodes in the network. Interactive heatmaps visualize inter- and cross-library TF modules to enable users to explore the data within the ChEA3 TF libraries. Overall, since ChEA3 is an enhanced version of the ChEA project, it is expected to guide many future experimental studies that aim to explore regulatory mechanisms in mammalian cells.

Subtle applications of gene expression are greatly located in biology, for example to trigger developmental pathways, respond to environmental stimuli, or adapt to new food sources. Practically any step of gene expression may also be modulated, from transcriptional initiation, to RNA processing, and to the put up-translational amendment of a protein. Gene law is main for viruses, prokaryotes and eukaryotes as it raises the flexibility and suppleness of an organism via allowing the mobile to express protein when wanted. Despite the fact that as early as 1951 Barbara McClintock confirmed interplay between two genetic loci, Activator (Ac) and Dissociator (Ds), within the color formation of maize seeds, the primary discovery of a gene legislation procedure is largely regarded to be the identification in 1961 of the lac operon, learned by means of Jacques Monod, where some enzymes concerned in lactose metabolism are expressed with the aid of the genome of E.

Furthermore, in multicellular organisms, gene legislation drives the approaches of mobile differentiation and morphogenesis, leading to the creation of specific mobilephone types that possess distinct gene expression profiles, and as a consequence produce distinctive proteins/have different ultrastructures that swimsuit them to their features (though all of them possess the genotype, which follows the equal genome sequence).

A2 Biology - Transcriptional control of gene expression (OCR A Chapter 19.2)
 
05:45
Here we'll be looking at the first level of gene expression regulation in eukaryotes, which is before transcription. The principle of this stage is to switch genes on or off, and this is decided by whether or not the RNA polymerase is allowed to bind to the gene for transcription to happen. This is dependent on the state of the chromatin which is altered by histone modification - if the histones are less positively charged (ie. more negative), the DNA will become less tightly wound around it, allowing the gene to become accessible to the RNA polymerase for transcription.

Robert Tjian (Berkeley/HHMI) Part 1: Gene regulation: An introduction
 
31:29
https://www.ibiology.org/genetics-and-gene-regulation/transcription-factors/ Transcription, the conversion of DNA to RNA, is one of the most fundamental processes in cell biology. However, only about 3% of our total DNA encodes genes to be transcribed. RNA polymerase II, the enzyme that transcribes DNA to RNA, relies on a large set of proteins known as transcription factors to recognize the coding sequences and to transcribe the correct genes, in the correct cell type, at the correct time. In Part 1 of his lecture, Tjian gives an overview of the complex and critical role that transcription factors play in regulating gene expression. How do different cells from the same organism, such as muscle cells, neurons and red blood cells, all of which have identical DNA, have such different phenotypes? Tjian addresses this question in his second lecture, where he expands on the mechanisms of gene regulation.

Lac Operon - gene regulation in prokaryotes
 
13:24
This lecture explains the lac operon and the regulation of gene expression in prokaryotes by lac operon. The lac operon consists of three structural genes, and a promoter, a terminator, regulator, and an operator. The three structural genes are: lacZ, lacY, and lacA. lacZ encodes β-galactosidase (LacZ), an intracellular enzyme that cleaves the disaccharide lactose into glucose and galactose. This video lecture will teach you the mechanism of lac operon. It will also explain the positive and negative regulation of Lac operon and how it is controlled in response to the presence of Glucose. This video will also help you to realize the difference between a catabolic and an anabolic operon.
