Cosimo Commisso (scientist)
Cosimo Commisso is a Canadian cell biologist and cancer researcher who has made significant advances in the field of cellular trafficking and cancer metabolism. Among his most notable contributions are the discovery and study of how macropinocytosis supports tumor cell growth and survival by serving as an amino acid supply route in Ras-mutated cancers. He is currently an associate professor in the Tumor Initiation and Maintenance Program at the Sanford Burnham Prebys Medical Discovery Institute NCI-designated Cancer Center NCI-designated Cancer Centers are a group of 71 cancer research institutions in the United States supported by the National Cancer Institute.

Pinocytosis
In cellular biology, pinocytosis, otherwise known as fluid endocytosis and bulk-phase pinocytosis, is a mode of endocytosis in which small molecules dissolved in extracellular fluid are brought into the cell through an invagination of the cell membrane, resulting in their containment within a small vesicle inside the cell. These pinocytotic vesicles then typically fuse with early endosomes to hydrolyze (break down) the particles. Pinocytosis is variably subdivided into categories depending on the molecular mechanism and the fate of the internalized molecules. Function In humans, this process occurs primarily for absorption of fat droplets. In endocytosis the cell plasma membrane extends and folds around desired extracellular material, forming a pouch that pinches off creating an internalized vesicle. The invaginated pinocytosis vesicles are much smaller than those generated by phagocytosis. The vesicles eventually fuse with the lysosome, whereupon the vesicle contents are digeste ...

Ras Superfamily
The Ras superfamily, derived from "Rat sarcoma virus", is a protein superfamily of small GTPases. Members of the superfamily are divided into families and subfamilies based on their structure, sequence and function. The five main families are Ras, Rho, Ran, Rab and Arf GTPases. The Ras family itself is further divided into 6 subfamilies: Ras, Ral, Rap, Rheb, Rad and Rit. ''Miro'' is a recent contributor to the superfamily. Each subfamily shares the common core G domain, which provides essential GTPase and nucleotide exchange activity. The surrounding sequence helps determine the functional specificity of the small GTPase, for example the 'Insert Loop', common to the Rho subfamily, specifically contributes to binding to effector proteins such as WASP. In general, the Ras family is responsible for cell proliferation: Rho for cell morphology, Ran for nuclear transport, and Rab and Arf for vesicle transport. Subfamilies and members The following is a list of human proteins belongi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cancer
Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. These contrast with benign tumors, which do not spread. Possible signs and symptoms include a lump, abnormal bleeding, prolonged cough, unexplained weight loss, and a change in bowel movements. While these symptoms may indicate cancer, they can also have other causes. Over 100 types of cancers affect humans. Tobacco use is the cause of about 22% of cancer deaths. Another 10% are due to obesity, poor diet, lack of physical activity or excessive drinking of alcohol. Other factors include certain infections, exposure to ionizing radiation, and environmental pollutants. In the developing world, 15% of cancers are due to infections such as ''Helicobacter pylori'', hepatitis B, hepatitis C, human papillomavirus infection, Epstein–Barr virus and human immunodeficiency virus (HIV). These factors act, at least partly, by changing the genes of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sanford Burnham Prebys Medical Discovery Institute
Sanford Burnham Prebys is a 501(c)(3) non-profit medical research institute focusing on basic and translational research, with major research programs in cancer, neurodegeneration, diabetes, infectious, inflammatory, and childhood diseases.

NCI-designated Cancer Center
NCI-designated Cancer Centers are a group of 71 cancer research institutions in the United States supported by the National Cancer Institute. Program Three designations are recognized: Comprehensive Cancer Centers, Clinical Cancer Centers, and Basic Laboratory Cancer Centers. As of 2022, there are 52 Comprehensive Cancer Centers, 12 Clinical Cancer Centers, and 7 Basic Laboratory Cancer Centers. Almost all are associated with a university. Receiving the NCI-designation places cancer centers among the top 4 percent of the approximately 1,500 cancer centers in the United States. The standards for ''Comprehensive Cancer Centers'' are the most restrictive of the types. These facilities must demonstrate expertise in each of three areas: laboratory, clinical, and behavioral and population-based research. Comprehensive Cancer Centers are expected to initiate and conduct early phase, innovative clinical trials and to participate in the NCI's cooperative groups by providing leadership and ...

Canadian Medical Researchers
Canadians (french: Canadiens) are people identified with the country of Canada. This connection may be residential, legal, historical or cultural. For most Canadians, many (or all) of these connections exist and are collectively the source of their being ''Canadian''. Canada is a multilingual and Multiculturalism, multicultural society home to people of groups of many different ethnic, religious, and national origins, with the majority of the population made up of Old World Immigration to Canada, immigrants and their descendants. Following the initial period of New France, French and then the much larger British colonization of the Americas, British colonization, different waves (or peaks) of immigration and settlement of non-indigenous peoples took place over the course of nearly two centuries and continue today. Elements of Indigenous, French, British, and more recent immigrant customs, languages, and religions have combined to form the culture of Canada, and thus a Canadian ...

Year Of Birth Missing (living People)
A year or annus is the orbital period of a planetary body, for example, the Earth, moving in its orbit around the Sun. Due to the Earth's axial tilt, the course of a year sees the passing of the seasons, marked by change in weather, the hours of daylight, and, consequently, vegetation and soil fertility. In temperate and subpolar regions around the planet, four seasons are generally recognized: spring, summer, autumn and winter. In tropical and subtropical regions, several geographical sectors do not present defined seasons; but in the seasonal tropics, the annual wet and dry seasons are recognized and tracked. A calendar year is an approximation of the number of days of the Earth's orbital period, as counted in a given calendar. The Gregorian calendar, or modern calendar, presents its calendar year to be either a common year of 365 days or a leap year of 366 days, as do the Julian calendars. For the Gregorian calendar, the average length of the calendar year (the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
