The demand of biodiesel that is a renewable, alternative fuel for fossil-based petrodiesel seems to keep increasing. Exploiting lipids of microalgae as a raw material for biodiesel is already technically feasible. To realize economical production of microalgal biodiesel, several factors or strategies should be addressed and improved. Especially, researches on improvement of lipid synthesis by genetic or metabolic engineering are now in early stage, and prospects of this field are bright, requiring concerns and interests of many researchers to put practical use of microalgal biodiesel forward.

This study was carried out to evaluate the seed quality of soybeans produced from upland and drained-paddy fields. Soybeans from drained-paddy field showed significantly higher in the 100 seeds weight and greater in the size of seed length than those from upland fields. However, there are no significant differences in seed width and thickness between upland and paddy fields. In case of Hunter's color value, the lightness (L) was significantly higher in the upland soybeans, but the a (redness) and b (yellowness) values were higher in the drained-paddy field soybeans. Seed appearance of drained-paddy field was poor than that of upland field. Soybeans produced from the drained-paddy field showed higher protein content, whereas, lipid and ash contents were higher in the upland field. Soybeans from upland field had lower contents of total amino acids compared to drained-paddy fields. No statistical differences were found in palmitic, linoleic, and linolenic, but stearic, oleic, saturated fatty acids (SFA), and unsaturated fatty acids (USFA) showed significant differences between soybean seeds from upland and drained-paddy fields. Genistein content was higher in the drained-paddy fields, while daidzein and glycitein contents were higher in the upland fields. This result suggested that the soil condition of drained-paddy field is more favorable to synthesis genistein than daidzein and glycitein.

Cancer is the leading cause of human deaths worldwide. Understanding the biology underlying the evolution of cancer is important for reducing the economic and social burden of cancer. In addition to genetic aberrations, recent studies demonstrate metabolic rewiring, such as aerobic glycolysis, glutamine dependency, accumulation of intermediates of glycolysis, and upregulation of lipid and amino acid synthesis, in several types of cancer to support their high demands on nutrients for building blocks and energy production. Moreover, oncogenic mutations are known to be associated with metabolic reprogramming in cancer, and these overall changes collectively influence tumor-microenvironment interactions and cancer progression. Accordingly, several agents targeting metabolic alterations in cancer have been extensively evaluated in preclinical and clinical settings. Additionally, metabolic reprogramming is considered a novel target to control cancers harboring un-targetable oncogenic alterations such as KRAS. Focusing on lung cancer, here, we highlight recent findings regarding metabolic rewiring in cancer, its association with oncogenic alterations, and therapeutic strategies to control deregulated metabolism in cancer.

The purpose of this study was to establish the selection of indicators for estimating and factors affecting the requirement of vitamin B6. There has been a need to establish the human requirements of vitamin $B_6$ since vitamin $B_6$ is thought to be involved in more than one hundred biochemical reactions as a coenzyme in the metabolism of amino acids, glucose, and lipid, and the synthesis of neurotransmitters. For the review of the literature, this study included from early findings of the sixties to studies of 2009. This study suggests that plasma pyridoxal 5' phosphate (PLP) is the best single indicator of vitamin $B_6$ status for the healthy but not for the non-healthy. Erythrocyte aspartate aminotransferase and alanine aminotransferase activation by PLP as an indirect measure and urinary 4-pyridoxic acid excretion as a direct measure are useful as supporting indicators. Bioavailability, nutrient interaction, physiological need, and chronic diseases may increase the requirement for vitamin $B_6$. However, these effects can not be quantified due to insufficient evidences.

This study was conducted to determine the effect of dietary salt on the synthesis of glucocorticoids in the adrenal cortex of mice. Mice had ad libitum access to 3% sodium chloride as the only drinking fluid (high salt diet) for either 4 days or 4 weeks. Adrenocortical expression of cytochrome P450 11beta-hydroxylase, a major regulatory enzyme in the biosynthesis of glucocorticoids, was examined by immunohistochemistry and western blot analysis. Ultrastructure of adrenocortical cell and plasma level of corticosterone were analyzed as well. Size and density of lipid droplets in the cortical cell were increased by high salt diet. Four days of high salt diet decreased P450 11beta-hydroxylase in the adrenal cortex, but 4 weeks increased it. Plasma level of corticosterone changed in parallel with the Cortical level of P450 11 beta-hydroxylase. These results suggest that high salt diet may modulate the biosynthesis of glucocorticoids, at least partly, via regulating the expression of P450 11beta-hydroxylase in adrenocortical cells.

Objective: Skeletal muscle is a crucial tissue from the perspectives of mitochondrial dysfunction and insulin resistance, it is formed by myogenesis which is dynamic multistep process to be myotubes. The authors could found that root of Atractylodes macrocephala Koidzumi (Atractylodis Rhizoma Alba, ARA) enhanced glucose and lipid metabolism in C2C12 myotubes via mitochondrial regulation. However its action in myogenesis process is not known. The aim of this work was the study of ARA on proliferation, differentiation and hypertrophy in C2C12 cells. Methods: To study proliferation phase, cells were incubated in growth medium with or without ARA (0.2 or 1.0 mg/ml) for 24 hours. To examine differentiation, at 70% confluence, cells were transferred in differentiation medium both with/without ARA (0.2 or 1.0 mg/ml) for 96 hours. And after 72 hours of differentiation, cells were treated with or without ARA (0.2 or 1.0 mg/ml) for 24 hours, the genesis of hypertrophy in myotubes were analyzed. Results: In proliferation phase, ARA could make difference in morphologic examination. In differentiation phase, it also made morphologic difference furthermore ARA (1.0 mg/ml) increased mRNA expressions of Myogenic regulatory factors and muscle-specific proteins synthesis. In late differentiation, ARA induced hypertrophic morphological changes in neo-formed myotubes. Conclusions: ARA might control cell cycle promoting myogenesis and hypertrophy in C2C12 cells.

Objectives: Alcoholic fatty liver is a potentially pathologic condition which can progress to steatohepatitis, fibrosis, and cirrhosis. The objective of this study is to investigate the effects of Scutellaria Radix (SR) extract on the alcoholic fatty liver induced by long-term EtOH administration. Results: Male Sprague Dawley rats were used in this study. All animals were randomly divided into Normal group, treated with saline (n=10); EtOH group, treated with ethanol (n=10); EtOH+SR group, treated with ethanol+Scutellaria Radix extract (n=10). For oral administration of ethanol in EtOH and EtOH+SR group, the ethanol was dissolved in distilled water in concentrations of 25% (v/v). Throughout the experiment of 8 week, the rats were allowed free access to water and standard chow. Sample group were administrated by Scutellaria Radix extract daily for 8 weeks. Results: The levels of hepatic marker such as aspartate aminotransferase and alanine aminotransferase were altered. Histopathological changes such as ballooning, fatty and hydropic degeneration were reduced and the expression of tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$) was significantly attenuated by Scutellaria Radix extract. Conclusions: These data suggest that Scutellaria Radix extract attenuated the alcoholic simple fatty liver by improving hepatic lipid metabolism via suppression of $TNF-{\alpha}$ protein. Scutellaria Radix could be effective in protecting the liver from alcoholic fatty liver.
