    Chemical composition and antiproliferative, antioxidant, and proapoptotic effects of fruiting body extracts of the lingzhi or reishi medicinal mushroom, ganoderma lucidum (Agaricomycetes), from India
    (Begell House Inc., 2016) Gill, B.S.; Sharma, P.; Navgeet, Kumar, S.
    Ganoderma lucidum is a renowned medicinal mushroom exploited as a panacea because of the broad spectrum of its bioactivities, which give it invaluable nutritional and clinical implications. This research was implemented with an incentive to explore and quantify various macromolecules encompassed in the oriental fungus; these vary in concentration with respect to the development/growth phase, host plants, and geographic location of collection. Chemical profiling of G. lucidum confirmed the presence of myco-constituents, their amounts varying in response to extreme climatic conditions. G. lucidum extract exhibited elevated levels of all myco-constituents but flavonoids, which were more pronounced when in a parasitic relationship with their host plants. Proapoptotic efficiency portrayed by the extracts against a prostate cancer cell line (PC-3) was also found to be similar. The samples collected from the Bathinda region, with Azadirachta and Acacia trees as the host plants, showed several-fold augmentation in levels of G. lucidum gredients compared with other variants. Elevated levels of myco-constituents highlight their significance in inhibiting prostate cancer cell proliferation, reducing reactive oxygen species, suppressing invasive potential, and inducing apoptosis. It was thus concluded that G. lucidum grown on Azadirachta plants was more efficient in exhibiting potent biological activities than G. lucidum grown on other host plants. ? 2016 Begell House, Inc.

    Ganoderma lucidum targeting lung cancer signaling: A review
    (SAGE Publications Ltd, 2017) Gill, Balraj Singh; Navgeet; Kumar, Sanjeev; Gill, B.S.; Navgeet, Kumar, S.
    Lung cancer causes huge mortality to population, and pharmaceutical companies require new drugs as an alternative either synthetic or natural targeting lung cancer. The conventional therapies cause side effects, and therefore, natural products are used as a therapeutic candidate in lung cancer. Chemical diversity among natural products highlights the impact of evolution and survival of fittest. One such neglected natural product is Ganoderma lucidum used for promoting health and longevity for a longer time. The major bioconstituents of G. lucidum are mainly terpenes, polysaccharides, and proteins, which were explored for various activities ranging from apoptosis to autophagy. The bioconstituents of G. lucidum activate plasma membrane receptors and initiate various downstream signaling leading to nuclear factor-?B, phosphoinositide 3-kinase, Akt, and mammalian target of rapamycin in cancer. The bioconstituents regulate the expression of various genes involved in cell cycle, immune response, apoptosis, and autophagy in lung cancer. This review highlights the inextricable role of G. lucidum and its bioconstituents in lung cancer signaling for the first time. ? The Author(s) 2017.
