Crane was born on December 20, 1919 in [[Palmyra, New Jersey]], to Wilbur Fiske Crane, architect and engineer, and Mary Elisabeth Crane. He is the grandson of [[Stephen Crane]]'s brother Wilbur.<ref>Robert K. Crane. "Stephen Crane's Family Heritage". Stephen Crane Studies 4.1, 1995.</ref>


==Early life==
⚫
He received a [[Bachelor of Science|B.S.]] from [[Washington College]] in 1942. After serving in the Navy during World War II, Crane studied in [[biochemistry]] with Eric Ball at [[Harvard University|Harvard]] from 1946 to 1949, then spent a year with [[Fritz Albert Lipmann|Fritz Lipmann]] at [[Harvard Medical School]], and received a [[Doctor of Philosophy|Ph.D.]] in Medical Sciences in 1950. He then joined [[Carl Ferdinand Cori|Carl Cori]]’s Department of Biological Chemistry at [[Washington University in St. Louis|Washington University]] School of Medicine in St. Louis, where he began his long interest in [[Carbohydrate metabolism|glucose metabolism]] and worked until 1962. After that, he was professor and chairman of the department of Biochemistry at the [[Chicago Medical School]] until 1966 and then became professor and chairman of the department of Physiology and Biophysics at Rutgers Medical School (now known as [[Robert Wood Johnson Medical School]]) of the [[University of Medicine and Dentistry of New Jersey]] until 1986.

==Discovery of cotransport==
⚫
In the 1950s, Crane played a central role in establishing that glucose transport into the cell was the first step in [[Carbohydrate metabolism|glucose metabolism]] and its control. He demonstrated that neither the [[phosphorylation]]-[[dephosphorylation]] nor other covalent reactions accounted for glucose transport in the intestine.

"Crane in 1961 was the first to formulate the [[Co-transport|cotransport]] concept to explain active transport [7].

The key point here was 'flux coupling', the [[Co-transport|cotransport]] of sodium and glucose in the apical membrane of the small intestinal epithelial cell.

Oral rehydration therapy saves the lives of millions of cholera patients in underdeveloped countries since the 1980s.<ref>W.B. Greenough. [[The Lancet|Lancet]] 345, June 1995, p. 1568. “The life saving power of oral rehydration therapy was first demonstrated in cholera patients. By 1971 there was sufficient knowledge to reduce death from 40% to less than 3%, even under chaotic field conditions ----- ‘Now used for all diarrheal diseases it’ saves the lives of over one million children a year and if fully used could save 3-4 million lives every year.”</ref> In 1978, [[The Lancet]] wrote : “the discovery that sodium transport and glucose transport are coupled in the small intestine, so that glucose accelerates absorption of solute and water, was potentially the most important medical advance this century.”<ref>Editorial. “Water with sugar and salt”.

Robert Kellogg Crane (December 20, 1919 – October 31, 2010) was an American biochemist best known for his discovery of sodium–glucose cotransport.

Early life

[edit]

Crane was born on December 20, 1919, in Palmyra, New Jersey, to Wilbur Fiske Crane, Jr. architect and engineer, and Mary Elizabeth McHale Crane. He is the grandson of Stephen Crane's brother Wilbur.[1]

He received a B.S. from Washington College in 1942. After serving in the Navy during World War II, Crane studied in biochemistry with Eric Ball at Harvard from 1946 to 1949, then spent a year with Fritz Lipmann at Harvard Medical School, and received a Ph.D. in Medical Sciences in 1950.

Career

[edit]

He joined Carl Cori's Department of Biological Chemistry at Washington University School of Medicine in St. Louis, where he began his long interest in glucose metabolism and worked until 1962. After that, he was professor and chairman of the department of Biochemistry at the Chicago Medical School until 1966 and then became professor and chairman of the department of Physiology and Biophysics at Rutgers Medical School (now known as Robert Wood Johnson Medical School) of the University of Medicine and Dentistry of New Jersey until 1986. He received a Sc.D. from Washington College in 1982.[2]

In the 1950s, Crane played a central role in establishing that glucose transport into the cell was the first step in glucose metabolism and its control. He demonstrated that neither the phosphorylation-dephosphorylation mechanism nor other covalent reactions accounted for glucose transport in the intestine.

Model of cotransport coupling of glucose transport to an Na+ pump by an Na+ circuit. Redrawn from Crane et al.[2][3]

In August 1960, in Prague, Crane presented for the first time his discovery of the sodium-glucose cotransport as the mechanism for intestinal glucose absorption.[3] Cotransport was the first ever proposal of flux coupling in biology and was the most important event concerning carbohydrate absorption in the 20th century.[4][5]

Crane's discovery of cotransport led directly to the development of oral rehydration therapy.[6][7] This treatment counterbalances the loss of water and electrolytes caused by cholera via a glucose containing salt solution that accelerates water and electrolyte absorption. This is possible because cholera does not interfere with sodium-glucose cotransport.[8][9]

Oral rehydration therapy saves the lives of millions of cholera patients in underdeveloped countries since the 1980s.[10] In 1978, The Lancet wrote: "the discovery that sodium transport and glucose transport are coupled in the small intestine, so that glucose accelerates absorption of solute and water, was potentially the most important medical advance this century."[11]

Crane's discovery is also used in blockbuster drugs, such as the SSRI Prozac, which treat depression by inhibiting the Na/serotonin cotransporters in the brain. Furthermore, major pharmaceutical companies are developing inhibitors of the Na/glucose cotransporters to treat diabetes and obesity.[12]

"Crane in 1961 was the first to formulate the cotransport concept to explain active transport [7]. Specifically, he proposed that the accumulation of glucose in the intestinal epithelium across the brush border membrane was coupled to downhill Na+ transport cross the brush border. This hypothesis was rapidly tested, refined and extended [to] encompass the active transport of a diverse range of molecules and ions into virtually every cell type.”

"The insight from this time that remains in all current text books is the notion of Robert Crane published originally as an appendix to a symposium paper published in 1960 (Crane et al. 1960). The key point here was 'flux coupling', the cotransport of sodium and glucose in the apical membrane of the small intestinal epithelial cell. Half a century later this idea has turned into one of the most studied of all transporter proteins (SGLT1), the sodium–glucose cotransporter."

Crane: "I have recently been reassured that this formulation of sodium ion-coupled glucose transport in the intestine was the basis for the development by others of the simple glucose-sodium chloride solution taken by mouth that is used world-wide to treat victims of life-threatening diarrhea as in cholera. A practical development based on my little piece of basic research has saved thousands upon thousands of lives."
