In the Sea of Japan and the Adriatic Sea, a COX1 DNA test revealed genetic similarity of Manila clams, although shell parameters, spermatogenesis patterns, and sperm characteristics are area specific
The two Manila clam forms living in the Sea of Japan and in the Adriatic Sea were compared genetically and morphologically to identify traits that could be used to authenticate these geographic forms. COX1 DNA...

Open AccessPredicting chemoresponsiveness in epithelial ovarian cancer patients using circulating small extracellular vesicle-derived plasma gelsolin
Resistance to chemotherapy continues to be a challenge when treating epithelial ovarian cancer (EOC), contributing to low patient survival rates. While CA125, the conventional EOC biomarker, has been useful in...

Open AccessIn the Asia-Pacific region, the COI DNA test revealed the divergence of the bivalve mollusc Mactra chinensis into three species; can these species be distinguished using shell coloration and sperm structure?
According to COI DNA barcoding testing, the marine bivalve mollusc Mactra chinensis, which is native to the Asia-Pacific region, diverged into three species. These species were preliminary characterized as M. chi...

VASA-induced cytoplasmic localization of CYTB-positive mitochondrial substance occurs by destructive and nondestructive mitochondrial effusion, respectively, in early and late spermatogenic cells of the Manila clam
To analyze the release of mitochondrial material, a process that is believed to be (i) induced by the VASA protein derived from germplasm granules, and (ii) which appears to play an important role during meiot...

Open AccessThe exosome-mediated autocrine and paracrine actions of plasma gelsolin in ovarian cancer chemoresistance
Ovarian cancer (OVCA) is the most lethal gynecological cancer, due predominantly to late presentation, high recurrence rate and common chemoresistance development. The expression of the actin-associated protei...

Open AccessVariation of sperm morphology in Pacific oyster precludes its use as a species marker but enables intraspecific geo-authentification and aquatic monitoring
According to recent reports, shell morphology is unreliable for the identification of oysters because of the high phenotypic plasticity of these bivalves. Using COI DNA barcoding and sperm morphology, we reinv...

Structural messenger RNA contains cytokeratin polymerization and depolymerization signals
We have previously shown that VegT mRNA plays a structural (translation-independent) role in the organization of the cytokeratin cytoskeleton in Xenopus oocytes. The depletion of VegT mRNA causes the fragmentatio...

Ultrastructural study of spermatogenesis in Phoronopsis harmeri (Lophophorata, Phoronida)
The process of sperm development in Phoronopsis harmeri was studied by electron microscopy. Develo** spermatogenical cells are aggregated around the capillaries of the haemal plexus. The spermatogonia, which ar...
