Silvestrol Induces Early Autophagy and Apoptosis in Human Melanoma Cells Wei-Lun Chen1, Li Pan2, A
Chen et al. BMC Cancer (2016) 16:17 DOI 10.1186/s12885-015-1988-0 RESEARCH ARTICLE Open Access Silvestrol induces early autophagy and apoptosis in human melanoma cells Wei-Lun Chen1, Li Pan2, A. Douglas Kinghorn2, Steven M. Swanson1,3 and Joanna E. Burdette1* Abstract Background: Silvestrol is a cyclopenta[b]benzofuran that was isolated from the fruits and twigs of Aglaia foveolata, a plant indigenous to Borneo in Southeast Asia. The purpose of the current study was to determine if inhibition of protein synthesis caused by silvestrol triggers autophagy and apoptosis in cultured human cancer cells derived from solid tumors. Methods: In vitro cell viability, flow cytometry, fluorescence microscopy, qPCR and immunoblot was used to study the mechanism of action of silvestrol in MDA-MB-435 melanoma cells. Results: By 24 h, a decrease in cyclin B and cyclin D expression was observed in silvestrol-treated cells relative to control. In addition, silvestrol blocked progression through the cell cycle at the G2-phase. In silvestrol-treated cells, DAPI staining of nuclear chromatin displayed nucleosomal fragments. Annexin V staining demonstrated an increase in apoptotic cells after silvestrol treatment. Silvestrol induced caspase-3 activation and apoptotic cell death in a time- and dose-dependent manner. Furthermore, both silvestrol and SAHA enhanced autophagosome formation in MDA-MB-435 cells. MDA-MB-435 cells responded to silvestrol treatment with accumulation of LC3-II and time-dependent p62 degradation. Bafilomycin A, an autophagy inhibitor, resulted in the accumulation of LC3 in cells treated with silvestrol. Silvestrol-mediated cell death was attenuated in ATG7-null mouse embryonic fibroblasts (MEFs) lacking a functional autophagy protein. -

Needless to say I was overjoyed to find Bob Jago unfolding his tea table for a pre walk cuppa. We were soon joined by Coralie Stuart and Anne Mohun. Anne and I had both come from a Treeforce planting event that morning, so we felt very intrepid to make the extra mission to a SGAP event all afternoon. In no time at all we four were huddled under a small interpretive shelter chatting, and playing "how many trees can Bob name while sitting down over smoko". The rain abated, and we were off. At the carpark I was interested in a striking prodigious orange fig with an attractive leaf and undulate leaf margin. Bob informed me this was the Ficus virgata, var. virgata . Trip trapping over the bridge, we saw the incredibly dainty Maesa haplobotrys , displaying fruit and flowers at all stages. Very attractive. The waters below were speckled with bright Syzygium luehmannii fruit. Up the hill, and water was playing across the path. Bob demonstrated the Rhodamnia spongiosa , with its incredibly pronounced three veined leaf. Myrtaceae are not particularly known for their three veined leaf structure, and I mused about whether many of the FNQ Lauraceae displayed this structural diagnostic. -

Phayre's Langur in Satchari National Park, Bangladesh
10 Asian Primates Journal 9(1), 2021 STATUS OF PHAYRE’S LANGUR Trachypithecus phayrei IN SATCHARI NATIONAL PARK, BANGLADESH Hassan Al-Razi1 and Habibon Naher2* Department of Zoology, Jagannath University, 9-11 Chittaranjan Avenue, Dhaka-1100, Bangladesh.1Email: chayan1999@ yahoo.com, 2Email: [email protected]. *Corresponding author ABSTRACT We studied the population status of Phayre’s Langur in Satchari National Park, Bangladesh, and threats to this population, from January to December 2016. We recorded 23 individuals in three groups. Group size ranged from four to 12 (mean 7.7±4.0) individuals; all groups contained a single adult male, 1–4 females and 2–7 immature individuals (subadults, juveniles and infants). Habitat encroachment for expansion of lemon orchards by the Tipra ethnic community and habitat degradation due to logging and firewood collection are the main threats to the primates. Road mortality, electrocution and tourist activities were additional causes of stress and mortality. Participatory work and awareness programmes with the Tipra community or generation of alternative income sources may reduce the dependency of local people on forest resources. Strict implementation of the rules and regulations of the Bangladesh Wildlife (Security and Conservation) Act 2012 can limit habitat encroachment and illegal logging, which should help in the conservation of this species. Key Words: Group composition, habitat encroachment, Satchari National Park.

The Flora of Peninsular Malaysia project is progressing remarkably well, with the fourth volume of the seed plants series released late last year. This volume includes eight taxonomic revisions, namely Actinidiaceae, Cabombaceae, Crypteroniaceae, Goodeniaceae, Meliaceae, Memecylaceae, Opiliaceae and Pandaceae, altogether 166 taxa in 29 genera. As anticipated, this volume is well structured and produced. The volume begins with a short chapter on conservation by L.S.L. Chua that includes two tables summarising (i) the number of native taxa for each Red List category assessed using the IUCN Red List Categories and Criteria (Version 3.1), and (ii) a list of threatened (i.e., Critically Endangered, Endangered and Vulnerable), Data Deficient and Rare taxa, recorded in the volume. The taxonomic accounts of the eight families are then presented in alphabetical order. The format of each revision is quite standard, as in any long-running Flora series, following styles adopted for the first volume. There are taxonomic keys provided to distinguish genera, as well as species, for all the families revised, and these keys are easy-to-use. The bulk of this volume is the account of the Meliaceae by D.J. Mabberley and C.M. Pannell, with a contribution by J.M. -

Robiansyah I. 2018. Diversity and biomass of tree species in Tambrauw, West Papua, Indonesia. Biodiversitas 19: 377-386. In spite of its high diversity and endemism, New Guinea is still one of the least explored regions on the globe. Flora information for the island as a whole is low compared to other areas in Malesia, and for Indonesian Province of Papua and West Papua it is much lower than for Papua New Guinea. To add more information and data on the flora of the West Papua Province, a vegetation analysis was conducted in Fef (442-509 m) and Bamusbama (757-914 m) Subdistricts, Tambrauw District, West Papua, Indonesia. Six and four plots of 30x30 m were placed in Fef and Bamusbama, respectively, to assess and compare the diversity and biomass of trees with diameter at breast height ≥ 10 cm. A total of 457 stems and ca. 86 tree species were identified. Fef accommodated higher species number (70) than Bamusbama (42). Meliaceae and Myrtaceae were the most important families in Fef and Bamusbama, respectively, while Castanopsis acuminatissima was the most important species in both subdistricts.The species diversity, richness, and evenness in Fef was higher than in Bamusbama. -
I Is the Sunda-Sahul Floristic Exchange Ongoing?
Is the Sunda-Sahul floristic exchange ongoing? A study of distributions, functional traits, climate and landscape genomics to investigate the invasion in Australian rainforests By Jia-Yee Samantha Yap Bachelor of Biotechnology Hons. A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2018 Queensland Alliance for Agriculture and Food Innovation i Abstract Australian rainforests are of mixed biogeographical histories, resulting from the collision between Sahul (Australia) and Sunda shelves that led to extensive immigration of rainforest lineages with Sunda ancestry to Australia. Although comprehensive fossil records and molecular phylogenies distinguish between the Sunda and Sahul floristic elements, species distributions, functional traits or landscape dynamics have not been used to distinguish between the two elements in the Australian rainforest flora. The overall aim of this study was to investigate both Sunda and Sahul components in the Australian rainforest flora by (1) exploring their continental-wide distributional patterns and observing how functional characteristics and environmental preferences determine these patterns, (2) investigating continental-wide genomic diversities and distances of multiple species and measuring local species accumulation rates across multiple sites to observe whether past biotic exchange left detectable and consistent patterns in the rainforest flora, (3) coupling genomic data and species distribution models of lineages of known Sunda and Sahul ancestry to examine landscape-level dynamics and habitat preferences to relate to the impact of historical processes. First, the continental distributions of rainforest woody representatives that could be ascribed to Sahul (795 species) and Sunda origins (604 species) and their dispersal and persistence characteristics and key functional characteristics (leaf size, fruit size, wood density and maximum height at maturity) of were compared. -

Biogeography and Ecology in a Pantropical Family, the Meliaceae
Gardens’ Bulletin Singapore 71(Suppl. 2):335-461. 2019 335 doi: 10.26492/gbs71(suppl. 2).2019-22 Biogeography and ecology in a pantropical family, the Meliaceae M. Heads Buffalo Museum of Science, 1020 Humboldt Parkway, Buffalo, NY 14211-1293, USA. [email protected] ABSTRACT. This paper reviews the biogeography and ecology of the family Meliaceae and maps many of the clades. Recently published molecular phylogenies are used as a framework to interpret distributional and ecological data. The sections on distribution concentrate on allopatry, on areas of overlap among clades, and on centres of diversity. The sections on ecology focus on populations of the family that are not in typical, dry-ground, lowland rain forest, for example, in and around mangrove forest, in peat swamp and other kinds of freshwater swamp forest, on limestone, and in open vegetation such as savanna woodland. Information on the altitudinal range of the genera is presented, and brief notes on architecture are also given. The paper considers the relationship between the distribution and ecology of the taxa, and the interpretation of the fossil record of the family, along with its significance for biogeographic studies. Finally, the paper discusses whether the evolution of Meliaceae can be attributed to ‘radiations’ from restricted centres of origin into new morphological, geographical and ecological space, or whether it is better explained by phases of vicariance in widespread ancestors, alternating with phases of range expansion. Keywords. Altitude, limestone, mangrove, rain forest, savanna, swamp forest, tropics, vicariance Introduction The family Meliaceae is well known for its high-quality timbers, especially mahogany (Swietenia Jacq.).
