Oncogenes

An oncogene is a gene which, in the right circumstances, can transform a cell into a tumour cell. 

Exogenous - originating outside the body, include viral oncogenes which may be introduced into cells by tumour viruses Endogenous  - genes that are normally present in the cell but have been altered to produce the oncogene - this alteration can be called activating.

  • Proto-oncogenes - “dominant” (only one allele necessary),  genes that normally help cells grow. When a proto-oncogene mutates, or there are too many copies of it, it becomes permanently activated and the cell grows out of control –> tumour.
  • Tumour suppressor genes - “recessive”,  normal genes that slow down cell division, repair DNA mistakes, or tell cells when to die (apoptosis). These are like the brakes of a car; when inactivated, cells grow out of control –> tumour. 

The functions of oncogenes can be altered by:

  • point mutations 
  • amplifications
  • gene rearrangements/translocations
  • deletions of part or all of the chromosome
  • altered expression*

*Altered expression/epigenetics 

Occurs without any mutational event - no change in the nucleotide sequence, therefore would not be picked up in DNA sequences. E.g. changes in the methylation patterns of the promoter region of the gene leads to an altered expression in the transcription of the mRNA and its translation.

I'm in a neuroscience PhD program and I just decided I would join my second rotation lab and the PI is happy to (and has money!) have me. While she has some ideas on what directions she wants me to take, specific ideas are up to me, and I'm feeling pretty stressed out trying to come up with something that's a thesis-worthy idea. How do I deal???

Hi there! And congrats! It sounds like you’re in a fantastic lab. 

I know it sounds daunting to come up with a thesis project, and it kinda is… but lets see if we can make it a bit more manageable by breaking it all down! So I’m not 100% sure what you mean by “specific ideas”, so I’m going to answer this in a very broad “how do i come up with a good PhD dissertation project?” kind of way. 

A PhD thesis should be an independent project but still related to your lab’s current work. I would strongly advise to not stray too far away from the parent projects of your lab. Picture the lab’s current research as a tree. You want your thesis project to be a branch–have it take its own direction, but still be able to gather resources (ie. funding, equipment, lab member expertise, preliminary data) from the trunk. 

So your process of deciding on a project could go something like this*: 

*If your PI already has a general idea/project overview she would like you to focus on, go ahead and skip to step 4

  1. Familiarize yourself with your lab’s specific field (by reading lots of papers), and your lab’s current projects (by reading the lab’s papers and grant applications, talking to the other members, etc). Find a few projects that have “future directions” or “future applications” that haven’t been explored yet in the field, but could have significance. 
  2. Meet with PI to discuss these ideas and whether any are feasible dissertation projects.
  3. Choose a potential project (or a few) together.
  4. Make a list of all the preliminary data–from your lab and from the field in general–surrounding that potential project (I like to make almost a word-vomit word doc of “what we know” and “what we don’t know” to get me going). Oftentimes as you study the existing data, a “hmm i wonder if…” pops up, which can be used as the start of a project or any specifics. 
  5. Meet with PI to go over these data (and any other ideas).
  6. Come up with a research question and then testable hypothesis (testable meaning it’s something that can be explored using the scientific method within the resources and time available to you).
  7. Meet with PI to go over the hypothesis and whether she thinks it’s feasible for a PhD project.
  8. Come up with 2-4 specific aims (aka mini-hypotheses that further break down your main hypothesis. I would highly recommend looking at your PI’s existing grant applications and/or PhD proposals of current and past students to get a sense for how to structure these aims).
  9. Meet with PI again to go over these aims.
  10. Come up with experimental approaches to each aim, along with predicted results and what they could mean in regards to the main hypothesis. 
  11. Meet with PI to discuss these.
  12. Rinse and repeat steps 8 - 11 ad nauseum until they approve (in the meantime you could be working on other things, like learning techniques, maybe prepping for Aim 1 if it’s pre-approved, etc). 
  13. Bonus: congrats! by creating specific aims, you’ve just started a grant proposal! perhaps you can submit it somewhere :O

As you can see, your PI should be involved in almost every step of the process. You truly want their guidance in all these early steps so you’re going in the right direction. There’s nothing worse for both parties involved for you to start on something in the lab that the PI doesn’t think is a good use of their money and your valuable time (and yes, your time is valuable!). It is also possible that at any point in this recipe you’ll have to start back at #1. I think I made 2 or 3 different PhD project proposals before my PI and I were happy with one (but on the bright side, she actually took one of the “tossed” ones and grew it into a full-fledged grant proposal for the whole lab, so yay!)

A more few things to keep in mind:

  • The research you do as a doctorate student is an avenue for you to learn the “Ph” part of your PhD: how to think outside the box and then apply it to your field. Your project is there for you to add tools to your toolbox. So if there’s a snazzy technique you’re itching to try that could work with your project, be sure to propose it. 
  • Coming up with a good solid project will take time. I think it took me almost half a year to get all the specifics down. There’s going to be a lot of reading, a lot of jotting down ideas and then crossing them off, and a lot of back-and-forth’s between you and your PI. And that’s all part of the process, and oh what an important process it is! So it’s ok to take your time. 
  • Your project may change as time goes on, and that’s ok. As it oftentimes happens in science, what we predict will happen doesn’t always occur (or it does, but there’s a variation). So it’s ok if say, you finish Aim 1, and your results are totally not expected and it ends up completely changing the trajectory of your project. That’s ok, because that’s science! 
  • Lastly, your PI probably has an entire project mapped out for you, but she wants to see if you have any ideas of your own because a) she wants to encourage your curiosity and passions, b) it’s good exercise and part of being a successful scientist, and c) new members of a research team sometimes have a different perspective on things and thus can come up with some really neat ideas! As my old PI used to say: “You hire a tech if you want stuff done; you hire a grad student if you want innovation.” 

I hope I answered your question! And if not, please let me know! I’m always happy to help to the best of my abilities. 

Best of luck, future Dr :)

Fun fact: I have terrible memory, so I need to do brute force exercises like this to memorize. I got tired of redrawing the chart over and over, but didn’t like the charts online, so I made this. 

If, for some reason, you don’t mind having something with my handwriting, feel free to use this! No need to credit–just learn!

The cs2 programs date back only a few years, and still have much of the functionality of today’s more modern ones. The differences between most of the versions are little more than slight modifications or additions of minor features, and UI changes. Go for it guys!!

am i the only person not affected by generalized positivity… like post it notes in bathrooms that say ‘you’re beautiful’ or posts that are like ‘smile! you are a beautiful sunshine flower!’ i’m just like … okay…

I just heard a psychologist (Guy Winch) say that the people that positive affirmations help most are actually the people who have high or at least normal self-esteem. They really do cheer those people up!

But for the rest of us they run so counter to our general worldview (we’re fundamentally bad and deserve nothing) that our brain rejects them immediately as lies and uses that moment to remind us of how terrible and abnormal we actually are.

What usually works for people with low self-esteem is stuff like writing out a list of very specific things we know we’re good at, and revisiting it every day to write a paragraph elaborating on one of those things (i.e. “I’m a compassionate person and here are five examples”) to try to set our brain on a different track long term.

That makes so much sense.

Dear internet,

Please give me all the advice you have on writing cover letters. Like, the closer you can get to literally just writing a cover letter for me, the better. Ok bye.

This is how I did the one for my librarian position.  I hope it helps.

Dear Person Hiring for this Job,

I am writing to ask you to consider me for X position.  This is a paragraph about why I want to do X position in general.  It includes at least one personal detail and at least one job skill I consider a particular strength.  It argues that I am passionate about this career.  It is not long.

I have had the opportunity to gain experience in this job by - paragraph about my work or study experience.  It should go from most recent experience back.  Include some details about your responsibilities/achievements in your most recent or most important positions.  If you have mostly study experience, give more detail about what exactly you studied.  If you shadowed people, mention that.  If your work experience is largely unrelated, try to shoehorn some of it in (e.g. I gained experience working with people by).  You can supplement with relevant hobbies.  (But if you do have recent, relevant work experience, you should largely be detailing that.  Only embroider the other stuff if you need to flesh it out.)  This should be the longest paragraph.

I hope you will consider allowing me to do X thing at your company.  This is a few sentences about why I want to work at your company in particular and what I think I could bring.  Try to mention at least one detail from the company website, so they know you visited it.  This is a short paragraph that parallels the first one.

Thank you very much for your time and attention.

Sincerely,

Person You Would Be a Fool Not to At Least Interview

oh my god thank you this is relevant to current interests

Two other points, to challenge what’s being said above a little:

1) Remember that the person reading this cover letter wants to know how you can contribute to the company. Not how excited you are about the position: it’s all about what they gain. Try framing the whole thing in that sense — “You would gain my X awesome skill that would help you Y with your mission.” “Here’s why I’m awesome and a great fit for making your company go better.”

2) At the end, ask for the interview. “I am available at PHONE NUMBER at your convenience. I look forward to speaking with you about this great opportunity soon.” Maybe even say you’ll be following up at a specific time and date. Ask for the job. People respond to that, and it’s a good way to fake confidence until you make it. Ask for the job.

Okay, three points. People reading cover letters get SO BORED going through them. Think about starting off with a story that relates to why you’re interested in the job, or that demonstrates a skill or a strong interest that would make you a good candidate. Be memorable — people remember stories, even (maybe especially) very little ones.

1. Have a Positive Mental Attitude- Prime yourself at being always comfortable and confident that u can do a lot better at studying. Remember that you are studying things that will prove to be valuable in real life.  2. Prepare your Work Space- Look for a place in your home or bedroom where u think u can study and maintain concentration in your work. Have materials stocked up and in place before your study. This way, u can finish your work without any interruptions.  3. Avoid Cramming- study an hour a day even when there’s no homework. Scan your notebooks and do a little advanced reading of your textbooks. You can also research through the internet to learn more about the topics u are covering in school.  I suggest google scholar, it’s like google but for students, it has the citations, and filters results so that only helpful outcomes appear. 4. Do projects with more enthusiasm and creativity- Don’t be afraid to think of new ideas or ways to present your homework or projects. Teachers always give additional points to students who show great effort in their works. SO, don’t be afraid to do something original, do something that hasn’t been done before. 5. Raise Your Hand- Be active and establish a friendly attitude towards your teachers. Offer to help them out in checking some work, filing papers or just carrying their things. Little good things add up in the end for that extra effort grade, and they’ll always remember you as a very helpful student.  6. Enjoy Reading the Latest News- Find connections or associations with your life as a student, as a child, as a friend, or as a citizen. Certain reports would always ask for u to react so better be ahead with current events which you may be affected with.  7. Listen to Your Teacher, take a few notes- In my experience, the more i copy and take down notes, the more i get lost in the lecture. It is best to listen first and understand before u jot down any important keywords. Yes, use keywords, simple doodles and arrows to make associations. These will help u remember all concepts mentally.  8. Keep Notes on Index Cards- I use personally use the smaller oxford ones, they are more portable honestly pretty aesthetic..   9. Watch TV Wisely- Yep you heard it, TV, when watching TV I sometimes pick up points which may seem relevant in my life. They sometimes even have something to do with what’s happening in class at the moment so, always initiate conversation about the latest shows and issues you have watched. Don’t be afraid to argue and defend your opinions.

If you get tired, learn to rest, not to quit.

We often feel like giving up because it’s too hard or too tiring. Just take a break, maybe a small break, or a long break. Rest, get motivated again, do what you need to do so that you can come back and keep working hard. Make yourself proud.
