Abstract
Macrofungi production and economic value have been increasing globally. The demand for macrofungi has expanded rapidly owing to their popularity among consumers, pleasant taste, and unique flavors. The presence of high quality proteins, polysaccharides, unsaturated fatty acids, minerals, triterpene sterols, and secondary metabolites makes macrofungi an important commodity. Macrofungi are well known for their ability to protect from or cure various health problems, such as immunodeficiency, cancer, inflammation, hypertension, hyperlipidemia, hypercholesterolemia, and obesity. Many studies have demonstrated their medicinal properties, supported by both in vivo and in vitro experimental studies, as well as clinical trials. Numerous bioactive compounds isolated from mushrooms, such as polysaccharides, proteins, fats, phenolic compounds, and vitamins, possess strong bioactivities. Consequently, they can be considered as an important source of nutraceuticals. Numerous edible mushrooms have been studied for their bioactivities, but only a few species have made it to the market. Many species remain to be explored. The converging trends and popularity of eastern herbal medicines, natural/organic food product preference, gut-healthy products, and positive outlook towards sports nutrition are supporting the growth in the medicinal mushroom market. The consumption of medicinal mushrooms as functional food or dietary supplement is expected to markedly increase in the future. The global medicinal mushroom market size is projected to increase by USD 13.88 billion from 2018 to 2022. The global market values of promising bioactive compounds, such as lentinan and lovastatin, are also expected to rise. With such a market growth, mushroom nutraceuticals hold to be very promising in the years to come.

Abstract
PURPOSE 3-hydroxy-3-methylglutaryl CoA reductase inhibitors (statins) are frequently used lipid-lowering drugs. Moreover, they are reported to exert pleiotropic effects on cellular stress responses, proliferation, and apoptosis. Whether statins affect the sensitivity of primary human cells to ionizing radiation (IR) is still unknown. The present study aims at answering this question. EXPERIMENTAL DESIGN The effect of lovastatin on IR-provoked cytotoxicity was analyzed in primary human umbilical vein endothelial cells (HUVEC). To this end, cell viability, proliferation, and apoptosis as well as DNA damage-related stress responses were investigated. RESULTS The data show that lovastatin protects HUVEC from IR-induced cell death. Lovastatin did not confer radioresistance to human fibroblasts. The radioprotective, antiapoptotic effect of lovastatin was observed at low, physiologically relevant dose level (1 micromol/L). Lovastatin affected various IR-induced stress responses in HUVEC: It attenuated the increase in p53/p21 protein level and impaired the activation of nuclear factor-kappaB, Chk-1, and Akt kinase but did not inhibit extracellular signal-regulated kinase activation. Exposure of HUVEC to IR did not change the level of Bax and Bcl-2 and did not cause activation of caspase-3, indicating that radioprotection by lovastatin does not depend on the modulation of the mitochondrial death pathway. Also, IR-induced DNA double-strand break formation and repair were not influenced by lovastatin. CONCLUSIONS The data show that lovastatin has multiple inhibitory effects on IR-stimulated DNA damage-dependent stress responses in HUVEC. Because lovastatin causes radioresistance, it might be useful in the clinic for attenuating side effects of radiation therapy that are related to endothelial cell damage.

Abstract
Although genotoxic agents are powerful inducers of stress kinases (SAPK/JNK), the contribution of DNA damage itself to this response is unknown. Therefore, SAPK/JNK activation of cells harboring specific defects in DNA damage-recognition mechanisms was studied. Dual phosphorylation of SAPK/JNK by the genotoxin methyl methanesulfonate (MMS) occurred in two waves. The early response (< or = 2 h after exposure) was similar in cells knockout for ATM, PARP, p53, and CSB or defective in DNA-PK(cs) compared with wild-type cells. The late response however (> or = 4 h), was drastically reduced in DNA-PK(cs) and Cockayne's syndrome B (CSB)-deficient cells. Similar results were obtained with human cells lacking DNA-PK(cs) and CSB. Activation of SAPK/JNK by MMS was not affected upon inhibition of base excision repair (BER), indicating base damage itself does not signal to SAPK/JNK. Because SAPK/JNK activation was attenuated in nongrowing cells, DNA replication-dependent processing of lesions, involving DNA-PK(cs) and CSB, appears to be required. DNA-PK(cs) coprecipitates with SEK1/MKK4 and SAPK/JNK, supporting a role of DNA-PK(cs) in SAPK/JNK activation. In this process, Rho GTPases are involved since inhibition of Rho impairs MMS-induced signaling to SAPK/JNK. The data show that sensing of DNA damage by DNA-PK(cs) and CSB causes a delayed SEK1/MKK4-mediated dual phosphorylation of SAPK/JNK.
