Complementary investigation and taxonomic identification of starfishes, (Echinodermata: Asteroidea) from the Northern Persian Gulf, Iran

Sea Stars are one of the most incredible creatures in the coastal and open waters. In this study, 11 species of starfishes have been identified which belonging to six genera and five families in northern islands of Persian Gulf during May 2017 to September 2018. Among the species, Astropecten hemprichi (Müller & Troschel, 1842), Astropecten indicus (Döderlein, 1888), Astropecten polyacanthus polyacanthus (Muller and Troschel, 1842), Astropecten polyacanthus phragmorous (Muller and Troschel, 1842), Luidia hardwicki (Gray, 1840), Aquilonastra iranica (Mortensen, 1940), Linckia multifora (Lamarck, 1816), Culcita novaeguineae (Muller & Troschel, 1842) and Pentaceraster mammillatus (Audouin, 1826) have been reported in the past. The species of Aquilonastra watersi (O'Loughlin and Rowe, 2006) and Linckia laevigata (Linnaeus, 1758) are new recordsin the Persian Gulf

Phylogenetic relationships of Scomberomorus commerson using sequence analysis of the mtDNA D-loop region in the Persian Gulf, Oman Sea and Arabian Sea

Abstract Narrow-barred Spanish mackerel, Scomberomorus commerson, is an epipelagic and migratory species of family Scombridae which have a significant role in terms of ecology and fishery. 100 samples were collected from the Persian Gulf, Oman Sea and Arabian Sea. Part of their dorsal fins was snipped and transferred to micro-tubes containing ethanol; then, DNAs were extracted and HRM-Real Time PCR was performed to designate representative specimens for sequencing. Phylogenetic relationships of S. commerson from Persian Gulf, Oman Sea and Arabian Sea were investigated using sequence data of mitochondrial DNA D-loop region. None clustered Neighbor Joining tree indicated the proximity amid S. commerson in four sites. As numbers demonstrated in sequence analyses of mitochondrial DNA D-Loop region a sublimely high degree of genetic similarity among S. commerson from the Persian Gulf and Oman Sea were perceived, thereafter, having one stock structure of S. commerson in four regions were proved, and this approximation can be merely justified by their migration process along the coasts of Oman Sea and Persian Gulf. Therefore, the assessment of distribution patterns of 20 haplotypes in the constructed phylogenetic tree using mtDNA D-Loop sequences ascertained that no significant clustering according to the sampling sites was concluded

Purified compounds from marine organism sea pen induce apoptosis in human breast cancer cell MDA-MB-231 and cervical cancer cell HeLa

Marine organisms are an important source of chemical compounds which are appropriate for use as therapeutic agents. Among them, Sea pens produce valuable chemical compounds being used as anti-cancer drugs. The aim of this study was to investigate anti-cancer property of extracted and purified compounds from marine organism Sea pen and evaluate their effects on inducing of apoptosis. The extracts were prepared from dried colony of Virgularia gustaviana. The compounds (3β)-Cholest,5en,3ol (cholesterol) (15 mg), Hexadecanoic acid (2.5 mg) and 2-Hexadecanol (10.7 mg) were identified by GC-MS and NMR. The cytotoxic effects of the compounds were evaluated on Hela and MDA-Mb-231 human cancer cell lines with MTT assay. Immunocytochemistry and Western Blot analyses were used to evaluate the expression of apoptosis related markers Caspase 3, Caspase 8, Bax and BCL2 in cancer cells after treating with three compounds. The purified compounds reduced viability of human breast cancer cell line MDA-MB-231 and human cervical cancer cell line Hela concentration-dependently. 2-Hexadecanol reduced significantly the viability of both cancer cell lines in comparison to the other purified compounds. Treatment of cancer cells with the three purified compounds increased the expression of caspase-3, caspase-8 and Bax proteins and decreased the relative Bcl-2/Bax ratio, demonstrating induction of apoptosis as possible mechanism of action. According to the results, three purified compounds inhibit the growth of cancer cells by inducing of apoptosis pathway; an effect which needs to be further investigated in the future studies

Predominance of clade D Symbiodinium in shallow-water reef-building corals off Kish and Larak Islands (Persian Gulf, Iran)

Scleractinian coral species harbour communities of photosynthetic taxa of the genus Symbiodinium. As many as eight genetic clades (A, B, C, D, E, F, G and H) of Symbiodinium have been discovered using molecular biology. These clades may differ from each other in their physiology, and thus influence the ecological distribution and resilience of their host corals to environmental stresses. Corals of the Persian Gulf are normally subject to extreme environmental conditions including high salinity and seasonal variation in temperature. This study is the first to use molecular techniques to identify the Symbiodinium of the Iranian coral reefs to the level of phylogenetic clades. Samples of eight coral species were collected at two different depths from the eastern part of Kish Island in the northern Persian Gulf, and Larak Island in the Strait of Hormuz. Partial 28S nuclear ribosomal (nr) DNA of Symbiodinium (D1/D2 domains) were amplified by polymerase chain reaction (PCR). PCR products were analyzed using single stranded conformational polymorphism and phylogenetic analyses of the LSU DNA sequences from a subset of the samples. The results showed that Symbiodinium populations were generally uniform among and within the populations of eight coral species studied, and there are at least two clades of Symbiodinium from Kish and Larak islands. Clade D was detected from eight of the coral species while clade C was found in two of species only (one species hosted two clades simultaneously). The dominance of clade D might be explained by high temperatures or the extreme temperature variation, typical of the Persian Gulf
