1.   Tumour suppressor genes seem to be very important in colorectal carcinogenesis.

2.   And genes also seem to influence not only dyslexia but less dramatic differences in reading skill, too.

3.   Another gene seemed to contribute to higher blood pressure in both whites and Mexican Americans, but not in blacks.

4.   But the cancer genes seem to be the same, whether a person is born with one or acquires one through an unfortunate mutation later in life.

5.   Some genes seem to promote longevity by making proteins that cells can use when they are under biological stress, said Tanzi.

6.   The genes seem to function for months.

7.   The gene seems to play a pivotal role in suppressing malignant changes, and when it is inactivated the breast cells become much more prone to cancer.

8.   Those liberated genes seem to do the heavy lifting in nerve cells to convert recent experience into long-term memory.

9.   To researchers, each gene initially seems like a piece of encrypted e-mail.
