Title Of The Study: Rice Compounds with Impact on Diabetes Control
Bran functional ingredients such as γ-oryzanol have been linked to several health benefits. In this study, the effects of rice glycemic index, macronutrients, and bioactive compounds on the pathological mechanisms associated with diabetes, identifying the rice compounds potentially exerting protective activities towards disease control are reviewed. The effects of starch, proteins, and bran bioactive compounds for diabetic control were reviewed and provide important insights about the nutritional quality of rice-based foods.

Title Of The Study: Hypolipidemic And Antioxidant Properties Of Oryzanol Concentrate In Reducing Diabetic Nephropathy Via SREBP1 Downregulation Rather Than Β-Oxidation / Bhaskaragoud G. Geetha V. Sharanappa T. Mohan Kumar A. S. Hema Kumar C. Suresh Kumar G. / Molecular Nutrition & Food Research
This study demonstrated that Gamma Oryzanol having hypolipidemic and antioxidant properties also downregulated the lipid biosynthesis through reduced SREBP-1-TGF-B interactions (EMSA) and could effectively ameliorate diabetic nephropathy.

Title Of The Study: A Novel Insulinotropic Mechanism Of Whole Grain-Derived Γ-Oryzanol Via The Suppression Of Local Dopamine D2 Receptor Signalling In Mouse Islet / Chisayo Kozuka, Sumito Sunagawa, Rei Ueda, Moritake Higa, Yuzuru Ohshiro, Hideaki Tanaka, Chigusa Shimizu-Okabe, Chitoshi Takayama, Masayuki Matsushita , Masato Tsutsui, Shogo Ishiuchi, Masanori Nakata, Toshihiko Yada, Jun-Ichi Miyazaki, Seiichi Oyadomari, Michio Shimabukuro, Hiroaki Masuzaki / British Journal Of Pharmacology
From the results of this study, it was concluded that Gamma Oryzanol exhibited unique anti-diabetic properties and the unexpected effects of Gamma Oryzanol on D receptor signalling in islets may provide a novel; natural food-based, approach to anti-diabetic therapy.

Title Of The Study: Renoprotective Effects Of Oryzanol In An Animal Model Of Experimentally Induced Diabetic Nephropathy /Somsuvra B. Ghatak And Shital S. Panchal / Oriental Pharmacy And Experimental Medicine
In this study, Oryzanol confirmed marked protection against functional and morphologic injuries in the kidneys of diabetic rats by modulating renal alterations, improving serum lipid profile and attenuating the markers of oxidative and/or nitrosative stress in renal tissues

Title Of The Study: Anti-Diabetic Activity Of Oryzanol And Its Relationship With The Anti- Oxidant Property /Somsuvra B. Ghatak And Shital S. Panchal / International Journal Of Diabetes In Developing Countries
The findings of this study indicate that Oryzanol possesses the potential to effectively ameliorate the oxidative stress induced by streptozotocin (STZ) and produce a reduction in blood glucose levels.
Year Of Study: 2012
Title Of The Study: Brown Rice And Its Component, Γ-Oryzanol, Attenuate The Preference For High-Fat Diet By Decreasing Hypothalamic Endoplasmic Reticulum Stress In Mice / Chisayo Kozuka, Kouichi Yabiku, Sumito Sunagawa, Rei Ueda, Shin-Ichiro Taira, Hiroyuki Ohshiro, Tomomi Ikema, Ken Yamakawa, Moritake Higa, Hideaki Tanaka, Chitoshi Takayama, Masayuki Matsushita, Seiichi Oyadomari, Michio Shimabukuro, Hiroaki Masuzaki / Diabetes.Diabetesjournals.Org
This study demonstrated that Gamma Oryzanol improves glucose intolerance and thereby prevents the risk of type 2 diabetes.
Year Of Study: 2012
Title Of The Study: Antidiabetic Effects Of A Standardized Egyptian Rice Bran Extract /Rebecca M Kaup, Mohamed T Khayyal, Eugen J Verspohl / Phytotherapy Research
The results of this study indicate that the prevalence of diabetes or at least a prediabetic (type 2) situation can be ameliorated by the rice bran extract. Gamma Oryzanol, which is a possible precursor of the insulinotropic compound ferulic acid is a candidate for this effect.
Year Of Study: 2010
Title Of The Study: Effect Of Oryzanol And Ferulic Acid On The Glucose Metabolism Of Mice Fed With A High-Fat Diet / Myoung Jin Son, Catherine W Rico, Seok Hyun Nam, Mi Young Kang / Journal Of Food Science
The results of this study illustrate that oryzanol could reduce the risk of high-fat-diet-induced hyperglycemia via the regulation of insulin secretion and hepatic glucose-regulating enzyme activities.
