Cuando veneno se convierte en tu medicamento para el dolor

Escrito en inglés por Attabey Rodríguez Benítez y editado por Patricia Garay, Alison Clair Ludzki y Noah Steinfeld. Traducido al español por Cristina E. María Ríos y editado por Attabey Rodríguez Benítez.

Imagina que no estás en el frígido Michigan sino nadando en las cálidas aguas del Mar Caribe. El agua tibia acaricia tu piel. Mientras te sumerges a lo largo de un arrecife colorido y rodeado por sinnúmero de peces, ves una anémona. Sabes que no puedes tocarla, pues podría picarte con sus toxinas. Pero, poco sabías que las anemonas no son las únicas capaces de picar. Los arrecifes albergan una criatura aún más hermosa y mortífera: el caracol cono. Aunque aparentan ser lindas e inofensivas, estas pequeñas criaturas pueden contener un cóctel de veneno de más de 100 toxinas. Sin embargo, si logran picarte, no sentirás ningún tipo de dolor. Este detalle en particular significó un cambio esencial en la carrera del Profesor Baldomero Olivera. El Dr. Olivera, un investigador en la Universidad de Utah, fue de estudiar síntesis de ADN a estudiar caracoles oriundos de las Filipinas.

When venom becomes your painkiller

Imagine you are not in frigid Michigan but are swimming in the warm waters of the Caribbean. The warm waters caress your skin. While you dive past a colorful reef with a plethora of fish, you see an anemone. You know you cannot touch it, because it might sting you with its toxins. Little do you know; these anemones are not the only ones capable of stinging. The reef harbors a far deadlier and more beautiful creature: cone snails. While cute on the outside, these little creatures can contain a venom cocktail of more than 100 toxins.  However, if they do sting, you will not feel any pain at all. This prompted a pivotal change in Professor Baldomero Olivera’s career. Dr. Olivero is a researcher currently at the University of Utah, where he transitioned from studying DNA synthesis to studying cone sails indigenous from his hometown in the Philippines.

 Who owns cells and DNA?  Property rights get messy in biology

Scattered around your house or apartment, lightly coating the surface of your coffee table and lurking in the nooks and crannies of each room, discarded layers of yourself can be found in the form of skin and hair cells. Regardless of how much of clean-freak you are, it’s unlikely you miss the over one million cells you shed per day. One might go so far as to say that they aren’t even yours in the first place as you sweep them up during a spring cleaning before irreverently dumping them in the waste bin. But what if someone came into your house and took them? Continue reading ” Who owns cells and DNA?  Property rights get messy in biology”

The influence of epigenetics in breast cancer therapeutics

Most likely, you know of someone diagnosed with breast cancer, which affects 1 in 8 women in the United States. Some of the reasons this disease is so difficult to treat are the lack of targeted therapies (as there are different subtypes of breast cancer) and tumor resistance to treatment. Therefore, scientists are investigating novel therapies that act on a specific component of the cancer and/or prevent this resistance. One exciting therapy alters the expression of certain genes; a gene needs to be expressed, or “turned on”, in order for the cell to obtain information from the gene and produce a product. This therapy is a promising approach since cancers, such as hormone-sensitive breast cancer, are often due to genetic mutations that result in an increase in gene expression. It is thought that using this therapy to alter gene expression will reverse the breast tumor’s resistance to treatment.

Are Omega-3 fatty acids healthy?

When I got sick as a child, my great-grandmother used to treat me with unpleasant fish oil. She would say, “bébete esto para que te pongas mejor y tengas un corazón fuerte” (“drink this so you can get better and have a strong heart”). Both of my parents also swore by fish oil, taking these enormous yellow pills, which I did not take myself because I was afraid to choke on them. These large fish oil pills were full of omega-3 fatty acids. My family explained that the supplements helped with high blood pressure, but never explained why they worked. As it turns out, there is still quite a lot of debate in the scientific community as to how omega-3s impact human health.

Microscopic Diversity: How and Why One Gene Creates Many Unique Proteins

Editors: Zena Lapp, Christina Vallianatos, and Whit Froehlich

The Human Genome Project is one of the greatest scientific accomplishments in recent history— this international collaboration identified almost all of the ~20,500 genes in the human body, known collectively as the genome. Now that scientists know the details of these genes, they are better able to understand and treat human diseases associated with genetic factors. However, despite the immense effort put forth by over 30 research labs for 13 years (1990-2003), the information we gained from this project is limited. Genes serve as guidebooks for cells in the body to build proteins; genes themselves don’t perform the necessary cellular functions—proteins do. So, while scientists have now known the nitty-gritty of thousands of human genes for a while, the details of their protein products, known collectively as the proteome, are still quite puzzling.

Methylated Memory

If you saw a hippo on campus, you would remember it. But, would you expect that seeing such a pachyderm roaming on a university would alter the expression of your DNA? A recent study found that rats placed in an environment that tested their memory had alterations to their DNA, or epigenetic changes.

For a long while, we have generally known that neurons within the hippocampus of our brains are responsible for memory. The current model for memory storage is due to the plasticity of neuronal connections, but researchers have recently found that it also involves active changes at the genetic level. These changes come from external factors and are linked to retaining long-term memories, which has implications in stress-related learning and memory disorders.

The After-Hours Life of a Protein

Editors: Zena Lapp, Jimmy Brancho, Noah Steinfeld

After you get home from work, perhaps after eating dinner, you may start working on other projects or hobbies. Humans aren’t the only ones that have a life after hours. Recently it’s been discovered that many proteins have roles in the cell outside of their main functions. This peculiar behavior led to the name ‘moonlighting,’ referencing individuals who have multiple jobs. A useful analogy might be a werewolf’s behavior under a full moon: being a person during the day, but a wolf at night.

Trasplante de Órganos de Cerdos a Humanos Podría Ser Posible en el Futuro Gracias a la Ingeniera Genética

Escrita por Attabey Rodríguez Benitez y editado por Cristina Maria Rios.

¿Te imaginas un futuro en el que los humanos podamos recibir órganos de animales en lugar de esperar por un donante? Esto podría ser posible gracias a una investigación llevada a cabo por una colaboración internacional entre laboratorios de Harvard y China que resultó en una publicación en la revista científica Science.
