In multi-cellular organisms, cells work individually and as a group to carry out tasks assigned to them by nature. For example, flat skin cells pack tightly into a layer that protects the underlying tissues from invasion by bacteria.
Long, thin muscle cells contract readily to move bones. The numerous extensions from a nerve cell enable it to connect to several other nerve cells in order to send and receive messages rapidly and efficiently.
Every cell has detailed instructions that dictate exactly how they replicate and function. These instructions are analogous to the blueprints that a builder uses to build a house; in the case of cells, however, the blueprints themselves must be duplicated along with cells before they divide so that each daughter cell can keep the instructions that it needs for its own replication. A unit of this instructions is called a gene. Genes determine the characteristics that a cell inherits, such as their shape, function and mode of reproduction.
Cells commit Suicide in a process called Apoptosis
Between 1969 and 1986, Sulston, Sir John E. and Horvitz, H. Robert in their study of cellular development in roundworm showed that millions of times per second cells commit suicide as an essential part of the normal cycle of cellular replacement. This also seems to be a check against disease: When mutations build up within a cell, the cell will usually self-destruct.
Apoptosis is a mechanism that allows cells to self-destruct when stimulated by the right trigger. This suicide act can be triggered by mild cellular injury and by various factors internal or external to the cell.
Horvitz, H. Robert identified 15 genes that play roles in cell suicide. Some of these genes instruct a cell to kill itself. Other genes direct cells to eat up neighbouring cells that die by suicide. He identified one gene that protects against cell suicide by interacting with other genes involved in the cell suicide process.
Cells and Angels
In ancient Greek religion, in Judaism and Christianity, and in Islam the relationship between God and man involves angels. An angel is seen as a divine messenger and a benevolent spirit that can function also as a protective guardian, as a heavenly warrior, and even as a cosmic power. Their primary function is to serve God and do his will. This is true of angels in both Christianity and Zoroastrianism, as well as in Judaism and Islam.
As functional extensions of the divine will, angels sometimes reward the faithful and punish the unjust or save the weak, who are in need of help, and destroy the wicked, who unjustly persecute their fellow creatures.
In the Same way, a nerve cell is a messenger that carries impulses (instructions, information, or command) from one part of the body to another. White blood cells function as a protective guardian to other cells. They are capable of motility and defend the body against infection and disease by ingesting foreign material and cellular debris by destroying infectious agents and cancer cells or by producing antibodies.
Originally, like angels, cells were instructed to carry out specific functions by a higher force. They were coded to have certain characters. We can say the codes and instructions for cells came from nature and that of angels came from God. Both angels and cells have specialized functions and worked for the general good of a larger existence.
These instructions and codes ensured order, harmony, discipline, efficiency and sustainability. Like individual angels and like choirs of angels, Cells can work individually and as a group to carry out jobs assigned to them by nature.
Cells Refuse to Commit Suicide
When a cell refuses to commit suicide, the cell may divide and give rise to mutated daughter cells, which continue to divide and spread, gradually forming a growth or tissue of undisciplined and malfunctioning rogue cells called a tumour.
This can be likened to the refusal of Iblis (the personal name of the devil) who was an angel to worship Adam, the first man, according to Islam. It was an angel rebelling against God. This act of disobedience transforms angels into demons. The refusal of a cell to commit suicide is also a rebellion but against nature. This act of disobedience turned body cells into cancerous cells.
According to Islam, angels are incapable of unbelief and always obey God. Followers of Islam view Satan as an angel who was unusual in his ability to defy God. It is also unusual for a cell to refuse to commit suicide at the end of its cycle or when it is damaged.
Tumours can stay localized to the area in which they arise and pose little risk to health. Such tumours are called benign but as tumours grow, they invade and destroy nearby healthy tissues. If they gain access to the circulatory or lymphatic systems, tumours can migrate throughout the body, seeding in distant areas (a process known as metastasis).
Tumours that grow and spread aggressively in this way are designated malignant, or cancerous. Left unchecked, they can spread throughout the body and disrupt organs that are necessary to keep an individual healthy and alive. These cells are malicious and like evil beings are destructive.
Cancerous Cells and Fallen Angels
Basic Christian ideas about demons originated from references to evil beings or “unclean spirits” in the Old Testament of the Bible. Islam also developed a complex system of demons. Muslim writings describe a group of evil beings, called jinn, who cause destruction and preside over places where evil activities take place. The original jinn was called Iblis.
In most English versions of the Bible, the term demon is translated as the devil, and in the New Testament, a demon is identified with an evil or malevolent spirit.
Tumour cells, especially cancerous ones, unlike healthy cells, exhibits characteristics of malevolence. They are like demons. Instead of repairing, building or protecting the body, these cells invade and destroy nearby healthy tissues. Hence a cell falls from good to evil, from benevolence to malevolence.
By the Middle Ages, Christian theology had developed an elaborate hierarchy of angels, who were associated with God, and fallen angels, or demons, who were led by Satan. Satan himself was considered the original fallen angel. Tumours like normal tissues in human originate from a single cancerous cell.
In a cancerous cell, permanent gene alterations, or mutations, cause the cell to malfunction. For a cell to become cancerous, usually three to seven different mutations must occur in a single cell. These genetic mutations may take many years to accumulate, but the convergence of mutations enables the cell to become cancerous. Cancer requires the suppression of apoptosis to allow survival of the abnormal tumour cells.
