Key – Week 10: Future Research

4. a) They are working on improving allergy diagnosis.

    b) birch, apples, carrot, peaches

5. With some allergens present in several substances, it is difficult to identify the source of the
allergy. It is the work of the researchers to break down the constituent parts of the potential
food alergen. They have to isolate, extract and purify each protein all the better to analyze its
structure and properties. The allergens thus purified make it possible to develop more reliable
methods of diagnosis.

6. apple, pear, hazelnut, peanut, coconut, mustard, sesame seed, potato, celeriac, cucumber

7. new diagnostic tool (biotech screening)– needs just 1 drop of blood for testing different
allergens

9. skin and breast cancer

10.

Research Done at:

The Department of Experimental Therapeutics at the University of Texas M.D.Anderson Cancer Center
in Houston (Paragraph 5)

Research Lead by:

Bharat Aggarval (Par. 5)

Research Reported in:

Journal Cancer (Par. 6)

Name of Compound:

Curcumin (Par. 2)

Compound Found in:

The spice curry and turmeric (Title+Par. 2)


11. a) It makes melanoma cells more likely to self-destruct. (Paragraph 3)
     It supresses 2 proteins that tumor cells use to keep themselves immortal., (Par. 6)

b)  Not yet  - just on mice. (paragraph 4) Clinical trials are planned. (par.8)

c) It has not been shown yet. (paragraph 10)

12. The present article is titled Curry Ingredient Fights Skin Cancer and was released at the
Journal Cancer. It deals with a substance that can fight some types of cancer. The name of the
substance is curcumin and is found in turmeric and curry. Tests have shown that this substance made
melanoma skin cancer cells more likely to self-destruct in a process known as apoptosis and also
that that the same substance helped stop the spread of breast cancer tumour cells to the lungs of
mice. So far the effects of curcumin have been tested in laboratory conditions, but clinical trials
are planned.
