TAG of the Week:

Complete your responses by Friday 11/21 at 5pm (EST).

Thank you to one of our HS320 students for tweeting this NPR clip.

As we had studied in class, genomics has the potential to prevent and treat many chronic diseases. DNA transplantation can be possible option as a part prenatal care testing and screening.

Listen to the NPR clip here, and discuss ethical issues that this type of 'prevention' strategy can have in our society?  Are we ready? Is the general public ready ? How could we (as health science professionals) prepare the general public about these options for 'prevention'?

Breast Cancer

TAG of the Week:



What is your initial reaction to this news story? 

Think back to the "In the Family' film and discuss how screening for breast cancer risk  at birth may have impacted the lives of those in the film.

If a cost effective screening process was developed, do you think children should be screened and all parents informed about their breast cancer risk directly following birth? Why or why not? Do you think such knowledge will have an impact on future health outcomes? What are the future implications of this research?

To screen or not to screen ...

TAG of the Week:

Blog #2 due on Friday Oct 24 at 5pm (EST)

Read or listen to the article from NPR: 



Brianne and Matthew Wojtesta's neurologist explained she has had times in the past that she's had to explain to a parent that their child may develop some form of this disease at some point. She states "I can't tell you when, I can't tell you what it's going to look like. I can't tell you if there's any way to prevent it. And I can't tell you that we will be able to treat it if it develops." You can imagine how difficult that may be for a family to hear. 

Consider the perspective of both the research community and a newborns family regarding this test. Who are the stakeholders and what are the ethical implications present here? What are some important things to take into account when deciding if this should be a screening test mandated to all newborns? Remember, getting this test early enough may help alleviate symptoms and has been proven to save a child's life. 

After reading the article, are you in support of Krabbe screening? Explain why or why not.

23andme and you ....

TAG of the Week: 


 Direct-to-consumer genetic testing companies such as 23andme have provided individuals the opportunity to learn about their genetic family history.

Read these two articles.  Are we (society) ready for this personalized genomic revolution?  What are your thoughts on blaming the consequences on the DTC companies? How do we remind consumer of personal responsibility? Support your post by discussing the positive and negative aspects of using these types of DTC genetic services.

My sporty genes

TAG of the Week:

Here it is:

Please read this New York Times Article, “Is Fitness All in the Genes?”


With everything that you have learned so far, do you believe fitness is purely based on one’s genome or is it a combined interaction of genetics and environmental factors (i.e. diet, workout routines, etc…)? Also, please comment on the potential limitations of the study outlined in this article.

Prevention Obestiy 911

TAG of the Week:

Obesity is now a  public health emergeny.

Read this week's reading on obesity, life-course perspective, and these two news link.
In your comment: briefly propose an intervention using the life-course theory to decrease obesity.

Our Family History

TAG of the Week:


Read this piece by the American Cancer Society entitled “Genetic Testing for Cancer: What You Need to Know”.


Given the increased awareness of genetic components/factors that predispose or cause diseases and/or conditions, do you believe it is imperative to know your family’s genetic history? Also, should public (i.e. Medicaid and/or Medicare) or private insurers provide genetic testing and counseling to their customers? Finally, if you had the opportunity, free of charge, would you participate in genetic testing and subsequent counseling?

ELSI in NBS

TAG of the Week:

Imagine this scenario: 

"The Government has my Baby's DNA! " cried a new mother who just found out her baby's blood has been sampled so the baby can be tested for a series of life-threatening diseases. While she is thankful that her baby has been tested negative, she is still upset that her baby's DNA remains in the hands of the government … Is that really true? If so, what's the big deal ? 

In the past few years, newborn screening programs across the world have taken some heat from the public. While the program was originally initiated to protect and to serve families, many advocates have taken a new twist to the population-based screening. General public miscommunication and misinterpretation of the original purpose of newborn screening could possibly shut down one of the most life-saving  and cost-effective programs for public health. 

Read this link, and compare your thoughts about the Scotland's situation with other countires (such as the US, UK, Asia … etc).  Incorporate what you've learned this week's lessons  and discuss the 'ethical, legal, and social issues' (ELSI) that have or have not been considered in this current news on newborn screening (NBS).  What would be your recommendations?

Animal Genome

CUTAG of the Week:


Many studies focusing on human disease have employed use non-human primate (NHP) or mamalian animal subjects, such as Rhesus monkeys and mice, respectively.  Other organisms, however, have genes comparable to those of people and the utility of their genomes being mapped for similar studies can be unfortunatey overlooked.  By observing zebrafish, genetic information crucial to the underlying mechanism of Native American myopathy has been gained.  What major limitations do the original researchers account for (original article citation is included at the bottom)?  Are their conclusions fairly and accurately summarized by Science Daily?

Better Drugs

CUTAG of the Week:


The p53 protein has been long-established as a tumor supressor protein and pharmaceuticals continue to accommodate its role in cancer in many of their drugs.  How do you think the present study’s findings will most likely affect future drug development?  What strategies would you choose to pursue as the most effective in addressing the p21/PUMA ratio discussed?

It's all about Organic

CUTAG of the Week:



In the recent decade we have seen a movement toward organic, antibiotic-free, and non-GMO (among other qualities) products.  Do you assent with much of the biotechnology industry, which claims altering organisms for mass production is no more harmful (and possibly better) than artificial selection and traditional agricultural methods?  What type of studies would demonstrate the benefits of GMOs?  What are some potential consequences that GMO advocates need to account concerning introducing new organisms into our environment?
