Splicing allows to create proteins with the coding sequence on the

mature mRNA.

The regulatory mechanism is given by the order in which the exons are located, if the same exons change the order, the

reading changes and thus also the protein.

Most cancer transcriptomes are

retention

Abnormal RNA splicing is

a common characteristic

of most cancers because

helps with the initiation

and metastasis.

Most cancer transcriptomes are

bloated by widespread intron

retention

The retention of introns on

abnormal splicing produced

an abnormal protein.

These retained introns were

specific to a particular

cancer, his deregulation may be usefull to

differentiating normal versus

cancerous cells.

Student’s observation:

I think the splicing process regarding a

global issue such as the cancer is, will have

a great impact , the deepening

knowledge will help the development of new therapies targeting tumor cells and

also to the prevention of cancer as a

disease and his expression.

'Decoding' gene regulation

Alternative splicing is a key step in

controlling gene expression, is also

linked to numerous human diseases.

Page 12: Splicing / Molecular Biology

'Decoding' gene regulation

Now, has been reported a

novel type of alternative

splicing that occurs in many

important genes on humans,

the exitron splicing.

'Decoding' gene regulation

Therefore, alternative splicing is giving

promising targets for clinical diagnosis

and therapeutic intervention.

Student’s observation:

I think this research promises a lot of hopes for

the future in the therapy and diagnosis

framework ,even being a theme to deepen, it

has great possibilities to find genes with high

medical relevance.

MEDICAL UTILITY

Page 16: Splicing / Molecular Biology

Medical Utility

Both investigations are

seeking the therapeutic

use of alternative

splicing.

Page 17: Splicing / Molecular Biology

The use of small molecules that inhibit

the splicing also have a anti-tumor

activity and it help to design novel

therapies targeting tumor cells.

Medical Utility

Page 18: Splicing / Molecular Biology

Control of gene expression with the

alternative splicing not only helps the

therapeutic treatment , also to the

prevention of diseases.
