Genomic integrity is a new 'big picture' concept to aid public health efforts and basically includes all the molecular genetic details of cells! While so many things we commonly choose to do can impact genomic integrity (also potentially affecting future generations!), environmental pollution, which we can rarely choose to avoid, particularly when waterways are affected, is a key problem. If pollution by mercury, which pollutes many areas where gold mining is pursued (legally or illegally), and exposure cannot be avoided by local populations, effects on genomic integrity are predicted.

One way to measure such effects of mercury pollution in cells is by using the micronucleus assay, which Hackuarium has been making 'open-source' for anyone interested.


Introduction

After a visit to the site of the old Hackuarium in November 2018 by members of MáS ARTE MáS ACCIóN, Rachel was surprised to be invited to Colombia by Fernando and Alejandra to join in co-constructing a project with a group of Swiss artists sponsored by ProHelvetia.
Concern about a mercury-empoisoned river, the Atrato, which had been recently given 'human rights,' the people living in its vicinity, and hoping to reach people in creative way, the current Hackuarium president, Rachel, jumped at the chance. Perhaps genomic integrity could be protected in the long run with some action...
Perhaps micronuclei workshops will be run with many kids from 3 locations during the next visit? (projected for 2020)

Main Goals

To help people learn about their cells, quantitative research methods, and risks to health, and make the world a better place.

Specific Objectives

To help people check their own inner cheek cells for levels of observable DNA damage by a classic method, the micronucleus assay.

To (perhaps) help provide evidence that 'bio-gold' is every bit as valuable as bio-foodstuffs!

Wondering if a picture of this magnificent Colombian woman, who posed so nicely for this photo

, carrying the tools of her trade (no mercury involved!), would be a suitable image for this campaign??

Protocol (Plan)

Setup description

Needs for workshop

The most important point of this wiki page in Hackuarium, is to define the needs and consumables for the simplest micronucleus assay, for 20 participants.
We can do this workshop for any age from 9 to 99, and hope you will want to try!

For 20 participants making 2 slides each, the basic needs for the workshop include:

  • 20 toothbrushes (always ask people to bring their own, as they say it takes 1000 years for a plastic toothbrush to degrade, and to make sure they are cleaned, as pelleting toothpaste residue with the cells is disappointing!)
  • saline solution (at least 200ml - can make with NaCl at 0.9% or get physiological solution at pharmacy)
  • 20 small glasses - to put 10ml into each, for washing off the collected cells
  • microcentrifuge - to pellet cells, this can be anything from a 'close and play' version, to real lab ware, and there is even a cute diy centrifuge that can be made out of an old hard drive, for a really fun extra part of workshops... (to add links)
  • 40 microcentrifuge tubes - two for each participant, to 'harvest' their cells
  • 20 transfer pipettes - to put the cells in saline into the centrifuge tubes
  • one box glass microscope slides (x50)
  • optional heating plate - to dry down cell 'smears' onto slides efficiently
  • lighter or other flaming device - to fix cells to the glass slide (flame around 3 seconds from below)
  • wooden pinchers or strong forceps - to hold slides while fixing cells with flame
  • Methanol:Acetic Acid Solution (about 20ml of a 3:1 mix, i.e. 15ml methanol + 5ml of glacial acetic acid) - this is listed as an optional fix in our standard protocol, but makes the stained cells look much nicer for scoring, so is generally recommended...
  • 0.5% methylene blue dye in Ethanol (0.5g MeBlue in 100ml) - to stain the cell nuclei (and micronuclei) blue
  • distilled water - to destain cells on the slides
  • gloves - to protect hands from dye
  • liquid waste containers (x4 is convenient - just glass cups work fine, saline can just go down the drain, but for meblue waste, I prefer running it over an activated charcoal filter, to avoid putting the dye down the drain - then want a funnel and activated charcoal powder too)
  • microscopes for scoring (at least 100-400x magnification is best, and being able to take pictures very useful - even cell phones through the objective can work, but many other options exist, diy too! -to add links...)


Space requirements

Anywhere with tables allowing space for 20 to collect samples, set up their slides, stain and look at their cells would work...
need water to rinse mouths and toothbrushes, and to wash hands
need power for the centrifuge and microscopes

Recommendations + next steps

a complete protocol is already in this wiki.
try it out, and tell us how it works for you!
