EPIGENÉTICA: O Controle Sobre os Genes Além do DNA A epigenética é o estudo de alterações no funcionamento dos genes que não envolvem mudanças na sequência do DNA. Enquanto o DNA carrega as informações genéticas que herdamos de nossos pais, a epigenética determina como, quando e onde esses genes serão ativados ou desativados. Em outras palavras, é como se o DNA fosse o "hardware" e a epigenética o "software" que controla como ele é usado. Como a epigenética funciona? A epigenética opera por meio de mecanismos que regulam a expressão gênica. Os principais processos incluem: 1. Metilação do DNA: Pequenos grupos químicos chamados grupos metil (CH3) são adicionados ao DNA, geralmente desligando os genes. É como colocar uma marca que impede que o gene seja lido. 2. Modificação das histonas: O DNA é enrolado em proteínas chamadas histonas. Alterações químicas nessas proteínas podem tornar o DNA mais ou menos acessível para leitura pelos maquinários celulares. 3. RNA não codificante: Moléculas de RNA podem interferir na produção de proteínas, regulando a expressão de genes. Fatores que influenciam a epigenética: A epigenética é altamente sensível ao ambiente. Fatores como alimentação, estresse, exposição a toxinas, exercício físico e até o envelhecimento podem modificar o padrão epigenético. Essas alterações, em alguns casos, podem ser transmitidas para as próximas gerações. A epigenética e a saúde: Alterações epigenéticas estão associadas a diversas condições de saúde, como câncer, doenças cardíacas, diabetes e transtornos psiquiátricos. Por exemplo, padrões anormais de metilação do DNA podem desativar genes supressores de tumores, contribuindo para o desenvolvimento do câncer. Epigenética no cotidiano: Um dos conceitos mais fascinantes da epigenética é que nosso estilo de vida pode moldar nossa saúde e a de nossos descendentes. Por isso, adotar uma alimentação balanceada, evitar o estresse crônico e praticar exercícios pode impactar positivamente nossa expressão genética. Continua nos comentarios 👇🏼.

A baby just became the first human to have his DNA rewritten while still alive. Meet KJ, nine months old from Philadelphia. One letter wrong in 3 billion DNA pairs. That single error meant his liver couldn’t process ammonia. Every time he ate, toxic waste flooded his brain. Doctors used CRISPR like a GPS system. Found the broken letter. Cut it out. Replaced it with a healthy copy. The entire treatment was designed in six months. Personalized gene therapy never tested before. FDA approved it in one week. Injected into his bloodstream at 6 months old. The therapy traveled to his liver. Found the broken gene. Rewrote his code from the inside. It worked. KJ can now eat without his brain shutting down. Sitting up. Rolling over. Hitting every milestone doctors said impossible. One baby. One treatment. Six months from diagnosis to cure. This isn’t science fiction anymore. We post educational content daily.

Same genes. Different expression. Two siblings. Same home. Same DNA. But very different daily choices. One nourishes the body with real food, moves, gets sunlight, sleeps on time. The other lives on processed food, screens, and late nights. At first, nothing looks very different. But the body is always listening. Hormones like growth hormone and IGF-1 don’t just depend on genetics, they respond to your lifestyle, every single day. Support the body, and it grows, repairs, and thrives. Disrupt it, and those same signals get blunted. Over time, the difference becomes visible: energy, posture, growth, resilience. This is not about perfection. It’s about consistency. Even across generations, we’ve seen this better lifestyles have led to better growth outcomes. Your genes are not your destiny. Your lifestyle is your daily vote. Because in the end, it’s not what you do once in a while, it’s what you do every single day that shapes your biology. #parenting #parents #health #children

Genotype is the complete set of genetic material that an organism inherits from its parents. It is the genetic makeup of an organism, and it determines the organism's traits. Genotype can be thought of as the instructions for building an organism. It contains the information for everything from the organism's eye color to its susceptibility to disease. Genotype is often compared to phenotype, which is the observable traits of an organism. For example, eye color is a phenotype, while the genotype for eye color is the specific combination of genes that determines eye color. Genotype is inherited from parents through reproduction. When two organisms mate, they pass on half of their genetic material to their offspring. This means that each offspring has a unique genotype, which is a combination of the genotypes of its parents. Genotype is important because it determines the organism's traits. These traits can affect the organism's survival, reproduction, and overall fitness. For example, an organism with a genotype that makes it resistant to disease is more likely to survive and reproduce than an organism with a genotype that makes it susceptible to disease. Here is a simple analogy to help you understand genotype: Imagine that genotype is like a recipe for baking a cake. The recipe contains all of the instructions for making the cake, including the ingredients, the amount of each ingredient, and the steps on how to mix and bake the cake. The ingredients in the recipe are like the genes in the genotype. The amount of each ingredient is like the number of copies of each gene that an organism has. And the steps on how to mix and bake the cake are like the instructions for how to build an organism from its genetic material. Just as different recipes can produce different cakes, different genotypes can produce different organisms. For example, the genotype for eye color can produce different eye colors, such as brown, blue, or green. Voiced @kaijinruh @facts_and_stuff_by_d #biology #genetics #gene #geneticengineering

Inbreeding among Indian families is increasing genetic health risks. What is inbreeding? Marrying within close family or the closed community, leads to reduced genetic diversity. This practice significantly raises the risk of passing on recessive genetic disorders. When both parents carry a recessive gene for a condition, the child has a 25% chance of inheriting two copies, resulting in the disorder. Common health problems caused by inbreeding: 1️⃣ Increased prevalence of genetic disorders like thalassemia, hemophilia, and sickle cell anemia. 2️⃣ Higher risk of diabetes, heart disease, and vision issues in offspring. 3️⃣ Reduced immunity and overall health due to limited genetic diversity. How can we escape this problem? 1️⃣ Marry outside the family or community to bring in diverse genes. 2️⃣ Follow the Gothra system to prevent genetic overlap. 3️⃣ Consider intercaste or even international marriages for healthier genetics. Let’s prioritize genetic health and ensure a brighter future for upcoming generations! #learnwithadithya #geneticdisorders #health #family #inbreeding #intercaste #marriage

This baby just became the first person in the world to have their DNA fixed using personalized gene editing. One tiny error. Out of 3 billion DNA letters. Fixed. Scientists used CRISPR, a tool that works like a GPS-guided scissor — it finds the exact faulty gene and repairs it. Why this matters: The same technology is already being tested for sickle cell disease, and could one day help prevent genetic cancers and inherited disorders. This is not sci-fi. This is happening right now. If you want more clear, hopeful science that actually explains the future — type JOIN and be part of the community. #Science #CRISPR #biotech

My husband’s genetics didn’t even try when it came to creating our family. Five boys in and not one of them looks like him. All shades of blonde, all basically photocopies of each other and then there’s Dan, dark and broody, standing next to them like he’s borrowed someone else’s kids for the day. People sometimes ask if he’s the dad (💀) and honestly, I get it. The contrast is wild. Same mannerisms, same laugh, same energy zero resemblance. But I will always find this question rude! Proof that genetics are a mystery, nature has a sense of humour, and my DNA really said I’ve got this ✨💪 Dan is still very much their dad and I can see him in the boys every day even if he looks like the plot twist to the untrained eye 🤍 #genetics #familyadventures #familygenes #minime #motherhood

This baby just became the first human in history to have his DNA rewritten while he was still alive. Meet KJ, a nine-month-old from Philadelphia who was born with a genetic error in his liver that should have killed him. Out of three billion DNA pairs in his body, just one letter was wrong. But that single error meant his liver couldn’t process ammonia, and every time he ate protein, toxic waste would flood his brain. But here’s what changed everything. Doctors didn’t give him a liver transplant or put him on lifelong medication. They used CRISPR like a GPS system to find that one broken letter in his DNA, cut it out with a molecular scissor, and replaced it with a healthy copy. Here’s where it gets insane. The entire treatment was designed and manufactured in six months. Scientists created a personalized gene editing therapy that had never been tested on anyone before, got FDA approval in one week, and injected it into KJ’s bloodstream when he was six months old. The therapy traveled straight to his liver, found the exact cell with the broken gene, and rewrote his genetic code from the inside. But the craziest part? It worked. KJ can now eat protein without his brain shutting down. He’s sitting up, rolling over, and hitting every milestone doctors said he’d never reach.
