The smaller arm is called P-arm and the longer arm is called Q-arm.

Based on linkage studies each of these arms are subdivided in P1, P2, p3 etc; similarly Q arms.

In mammals, the Rho family is thus made of 20 members distributed in 8 subfamilies: Rho, Rnd, Rho D/F, Rho H, Rac, Cdc42, Rho U/V and Rho BTB.

By the mid-1990s, Rho proteins had been observed to affect the formation of cellular projections ("processes") in fibroblasts.

In a 1998 review article, Alan Hall compiled evidence showing that not only do fibroblasts form processes upon Rho activation, but so do virtually all eukaryotic cells.

The Rho family of GTPases belong to the Ras superfamily of proteins, which consists of over 150 varieties in mammals. These 22 mammalian members are subdivided in the Rac subfamily (Rac1, Rac2, Rac3, and Rho G), Cdc42 subfamily (Cdc42, TC10, TCL, Chip, and Wrch-1), Rho A subfamlly (Rho A, Rho B, and Rho C) and other Rho GTPases (Rho E/Rnd3, Rho H/TTF, Rif, Rho BTB1, Rho BTB2, Miro-1, Miro-2, Rho D, Rnd1, and Rnd2).

Most of the eukaryotic genes contain introns, which are removed from the pre-RNA during RNA processing.) has an important role in the maintenance of normal cell function, and hence this parameter has to be tightly controlled within a narrow range, largely through the activity of transporters located at the plasma membrane.These transporters can be modulated by endogenous or exogenous molecules as well as, in some pathological situations, leading to p HApoptosis, or programmed cell death, is a physiological process essential for normal tissue development and homeostasis.This review will summarize the interactions among cancerous and immune cell types, as well as the key cytokine signals that are required for tumors to survive immunoediting in a dormant state or to grow and spread by escaping it.

Additionally, it will present examples of how probing secreted cell–cell signal networks in the tumor microenvironment (TME) with cytokine screens have contributed to our current understanding of these processes and discuss the implications of this understanding to antitumor therapies.
