The giant barrel sponge Xestospongia testudinaria is an ecologically important species that widely distributed across the Indo-Pacific. Little known, however, about precise biogeographic distribution and amount of morphological genetic variation in this species. Here we provide first detailed, fine-scaled (<200 km2) study composition X. around Lembeh Island, Indonesia. Two mitochondrial (CO1 ATP6 genes) one nuclear (ATP synthase β intron) DNA markers were used to assess variation. We...

Cancer can arise from the malignant transformation of normal cells due to carcinogenic induction that damages DNA and disrupts cell cycle. damage is corrected in G1 phase cycle by expression activation p53 tumor suppressor. The prominent outcomes are arrest apoptosis. Therefore, used as a target for anticancer drug development. Hyperactivation or deregulation MAPK (mitogen activated protein kinase) pathway affect liver cancer. plays an important role regulating inflammation associated with...

Sponge species are infamously difficult to identify for non-experts due their high morphological plasticity and the paucity of informative characters. The use molecular techniques certainly helps with identification, but unfortunately it requires prior reference sequences. Holotypes constitute best material however usage in systematics taxonomy is scarce frequently not even attempted, mostly antiquity preservation history. Here we provide case studies which demonstrate importance using...

The Indonesian archipelago is a ‘hotspot’ for invertebrate biodiversity (‘Coral Triangle’). In this area of ‘peak’ biodiversity, the origins high species diversity have often been debated. Xestospongia testudinaria one sponge that dominates coral reef communities in region. role so-called ‘giant barrel sponge’ ecosystem has studied repeatedly, as its various bioactive compounds. However, genetic variation iconic region remains unknown. We investigate over 200 samples from Indonesia, and...

Microplastics are plastic fragments in the size range of &gt;1 μm to &lt;5 mm. a global concern because their presence various ecosystems organisms and tendency hurt organisms. Due small size, microplastics can be easily ingested by organisms, including sponges. Freshwater sponges rare world. As filter feeder organism, accumulate into bodies. This study aims analyze physical characteristics microplastic abundance freshwater Porong River, Mojokerto City, East Java. Oncosclera asiatica...

The use of nuclear markers, in addition to traditional mitochondrial helps clarify hidden patterns genetic structure natural populations (Palumbi &amp; Baker, 1994). This is particularly evident among demosponges that possess slow evolutionary rates compared Bilateria, where intron markers can aid the understanding shallow level phylogenetic relationships (Shearer et al., 2002). Ideally, these (i) are well-conserved across different lineages, (ii) produce amplicons holding a number sites...

Desa Oro-oro Ombo memiliki letak yang strategis di dekat Kota Batu dengan kondisi iklim sangat mendukung untuk pertanian tanaman dan produk herbal. Pada tahun 2003 WHO merekomendasikan pemanfaatan obat tradisional herbal kesehatan, baik pencegahan maupun pengobatan, terutama penyakit kronis, degeneratif, kanker. Namun bertolak belakang pernyataan tersebut, konsumsi kalangan generasi muda menunjukkan penurunan. Penyebabnya karena rasanya pahit tidak praktis. Maka dari itu perlu adanya...
