Genetic testing for illness with no cure

things that need to be submitted 

a annotated biography, a image that depict the topic and one of the option from step 3

1. Research the topic and select five  primary source scientific articles to write about.

• identify five articles 

  at least three should be primary sources
  one can be a review
  one can be a secondary source
  the secondary source cannot be the same story as any of the primary sources

  2. Design an image using photos from different sources OR draw your own to depict what your topic looks like to you.
  3Create a research journal, podcast, video or portfolio to disseminate the information.

Annotated Bibliography

An annotated bibliography is a list of citations for papers relevant to a particular topic accompanied by a
bulleted summary (annotation) of each paper. For more information about annotated bibliographies:
https://owl.english.purdue.edu/owl/resource/614/01/

Assignment: Find 3 sources of primary literature that specifically identifies your topic and create an annotated
bibliography on those articles. This is an individual assignment. You should begin your search on
Pubmed.gov. This is a repository of peer-reviewed primary source articles. You may also use Google Scholar.
You may not use reviews or secondary sources. There are examples of these three article types on
Blackboard.

Format:

1. APA-style Citation of the article
2. Describe the research question or problem addressed in this paper

3. Describe the methods

a. What subjects were used

b. What experiments were performed

4. List a minimum of 3 main findings, conclusions, or main points

a. Include the figure/table from results, if necessary

5. State the relevance of these conclusions to your study

DO’s:

 Be sure to identify relevant literature. This will assist you in determining your specific research
question and formulating the introduction/background information.

 Write more, never less. I have to read and grade this assignment not you; so do not be concerned
about the length.

 PARAPHRASE the material. Read the article. Understand the article. Restate the information.

 Include all relevant information listed in the format above.

 You can find more than 3 articles. You may need them later.

DON’Ts:

 DO NOT COPY INFORMATION DIRECTLY FROM ANY PART OF THE ARTICLE. THIS IS CALLED
PLAGIARISM!

 Do not purchase articles. Try to access articles that require payment or subscription using the BSU
library services

 Do NOT write one sentence answers for the sections.

BIOL 209 Annotated Bibliography Example

1. APA-style Citation of the article

Smith A.J. et al. (2021). A genetic basis for friendship? Homophily for membrane-associated PDE11A-cAMP-CREB

signaling in CA1 of hippocampus dictates mutual social preference in male and female mice. Molecular Psychiatry,

26, 7107 – 7117. https://doi.org/10.1038/s41380-021-01237-4

2. Describe the research question or problem addressed in this paper

Previous studies have shown that friendships can have physical and mental benefits including a reduction in

mortality and morbidity risks and cognitive declines. Although these benefits are evident, the neurobiological

mechanisms underlying them are not. Additionally, long-term friendships are seen in different species allowing for

the use of a model organism to study the molecular mechanisms in a controlled experiment. This research uses a

model mouse to determine if the genetics of PDE11A is important in establishing friendships.

3. Describe the methods

a. What subjects were used

Adolescent and adult female and male pde11a knockout mice and BALB/cJ mice were used. C57BL/6 were

referenced from prior experiments.

b. What experiments were performed

The following experiments were used to obtain results: Immunofluorescence of PDE11A4 in brain samples,

Western blots of PDE11A4 and actin, social approach/avoidance, social preference assay (mouse psychiatry

assay), social odor detection and preference, PDE activity and stereotactic surgeries targeting CA1 of

hippocampus.

NOTE: This can be detailed or an overview, but make sure you state all subjects (all, genotype, sex and

samples, if possible) and all experiments.

4. List a minimum of 3 main findings, conclusions, or main points

a. Include the figure/table from results, if necessary

 The genetic background of the mice affect the social preference of mouse vs object.
C57BL/6 had reduced social approach and BALB/cJ had a change in the social preference.

 In adult and adolescent mice, regardless of sex, Pde11a genotype dictates mutual social
preference. KO mice rather interact with other KO mice than WT mice.

 PDE11A homophily is a driver of mutual social preference, but the exact mechanism is still
unknown.
NOTE: These statements should come from the results and/or discussion of the paper.
Make sure they make sense and are not repetitive. You may have to elaborate briefly.

5. State the relevance of these conclusions to your project

I am trying to find the reasons why certain people has lasting friendship and others are short-lived.
This study states that there are genetic basis to different similarities in people like alcoholism.
Additionally, it shows that the genotype for pde11a can be a contributing factor. This will allow me to
potentially identify other molecular mechanisms of friendships.

NOTE: Discuss the reason(s) you chose this article and how the contents relate to your project.

6. State the relevance of these conclusions to the field

I think this research will allow researchers to make genetic connections between friendships that could
be linked to the physical and mental benefits experiences. Additionally, the authors think that it is
possible to develop markers that predict compatibility. Imagine the new “online” dating profiles if this
becomes a reality!

NOTE: Discuss the implications the results/conclusions have to the overall field of study. How does it
advance the field and/or science?
