(Harvard/XVIVO)  Powering the Cell: Mitochondria

Together Harvard University and XVIVO developed this 3D animation journey for Harvard's undergraduate Molecular and Cellular Biology students about the microscopic world of mitochondria. The animation highlights the creation of Adenosine Triphosphate (ATP) -- mobile molecules which store chemical energy derived from the breakdown of carbon-based food. ATP molecules act as a kind of currency, imparting chemical energy to power all the functional components of cellular activity. This piece is the second in a series of award winning animations XVIVO is creating for Harvard's educational website BioVisions at Harvard. The first program, Inner Life of the Cell, received international acclaim and can be seen both on our website and the BioVisions site.

(Harvard/XVIVO)  Harvard University and XVIVO come together again to add to the growing series of scientific animations for BioVisions -- Harvard's multimedia lab in the department of Molecular and Cellular Biology. 'Protein Packing' strives to more accurately depict the molecular chaos in each and every cell, with proteins jittering around in what may seem like random motion. Proteins occupy roughly 40% of the cytoplasm, creating an environment that risks unintentional interaction and aggregation. Via diffusion and motor protein transport, these molecules are directed to sites where they are needed.

Három év kemény munkája nyert értelmet most. Van csodálatosabb dolog, mint hogy százmilliárd sejtünk azon ügyködik, hogy mi itt lehessünk? Lássunk, körmöt növesszünk, fület vakarjunk, sebet gyógyítsunk, kutyát simogassunk? <3

A few years ago, Harvard's BioVisions group put out some really amazing videos, including The Inner Life of the Cell embedded here. Unfortunately, for all their intricate and true-to-life visual detail, there isn't narration to describe the things you're seeing. I'm going to work through this video and their others, but for now just enjoy! (My favorite is the motor protein featured starting at 3:40.)

Inner Life of a Cell | Protein Packing (NT TImes)

Two years ago, BioVisions and Xvivo set out to upgrade their animations by capturing some of the messy complexity of protein movements. They wanted to cram a virtual cell with proteins at a more realistic density, and then have them jitter and collide

In this movie, we enter a neuron by diving through a channel on its surface. Once inside, we’re instantly surrounded by a swarm of molecules. We push through the crowd until we reach a proteasome, a barrel-shaped molecule that shreds damaged proteins so their components can be used to make new proteins.

Once more we see a vesicle being hauled by kinesin. But in this version, the kinesin doesn’t look like a molecule out for a stroll. Its movements are barely constrained randomness.

Every now and then, a tiny molecule loaded with fuel binds to one of the kinesin “feet.” It delivers a jolt of energy, causing that foot to leap off the molecular cable and flail wildly, pulling hard on the foot that’s still anchored. Eventually, the gyrating foot stumbles into contact again with the cable, locking on once more — and advancing the vesicle a tiny step forward.

This updated movie offers a better way to picture our most intricate inner workings. For one thing, it helps us to understand why we become sick. A number of diseases, such as Alzheimer’s and Parkinson’s, are caused when defective proteins clamp onto other proteins, creating toxic clumps.
