About This Presentation

Description : Check out this medical PowerPoint presentation titled "Molecular Basis of Cancer".
This medical PowerPoint presentation talks about the molecular basis of cancer, the understanding of which is critical for developing new treatments and improving patient outcomes.
Cancer is a complex disease that can arise from a variety of genetic and environmental factors. At its core, cancer is caused by the uncontrolled growth and division of abnormal cells within the body. These cells are able to grow and divide uncontrollably because they have acquired mutations or other genetic changes that allow them to bypass the normal regulatory mechanisms that keep cells in check.
The molecular basis of cancer involves a wide range of cellular processes that are disrupted in cancer cells.

Transcript

Slide 1-

Molecular Basis Of Cancer Non-lethal genetic damage lies at the heart of carcinogenesis Genetic hypothesis of cancer implies that a tumor mass result from the clonal expansion of a single progenitor cell that incurred the genetic damage
Slide 2-

Types of Normal Cellular Genes 3 Normal regulatory genes; - Growth promoting protooncogene -Growth inhibiting tumor suppressor gene -Gene regulate apoptosis 4th-- DNA repair gene
Slide 3-

Normal cell growth Any external stimuli leads to stimulation of growth by growth stimulating gene called Proto-oncogene This should be stopped by gene which will control the growth called Tumor suppressor gene Any mutated gene will be either repaired by DNA repair gene or killed by gene called apoptosis gene

Principles of Carcinogenesis Neoplastic transformation is a progressive process involving multiple “hits” or genetic changes. Alterations in DNA cause changes in one or more of the following types of genes: Proto- oncogenes Tumor suppressor genes Genes regulate apoptosis DNA repair genes

Tumor Development and Growth Transformation Growth of transformed cells Invasion of tumor cells into the surrounding tissues Metastasis of tumor cells to distant sites

Hallmarks of Cancer Self sufficiency in growth factors Insensitivity to growth-inhibitory signals Evasion of apoptosis Limitless replicative potential Sustained angiogenesis Ability to invade and metastasize Six fundamental changes of cell Physiology
