A 34-KD protein encoded by the SEI-1 gene (p34(SEI‑1)), is a relatively recently discovered oncoprotein that has multiple important biological functions. Our data show that p34(SEI-1) enhances cancer cell survival and promotes tumorigenesis by downregulating the tumor suppressor PTEN, a negative regulator of the PI3K/AKT signaling pathway, and therefore(More)
Angelica genus (umbelliferae) has traditionally been used as the medicine and health food considered alleviating several used in the treatment of cancer as well as non-cancerous diseases. Angelica purpuraefolia Chung is an endemic species and a folk medicine in Korea. We have previously reported that two natural khellactone isolated from the rhizomes of A.(More)
Paulownia coreana has traditionally been used as the medicine and health food in the treatment of cancer and infectious diseases. In the present study, a new antiproliferation agent, isoatriplicolide tiglate (PCAC) was isolated from the chloroform soluble fraction of the leaves of Paulownia coreana. The antiproliferation activities of PCAC plant extract was(More)
Local mRNA translation mediates the adaptive responses of axons to extrinsic signals, but direct evidence that it occurs in mammalian CNS axons in vivo is scant. We developed an axon-TRAP-RiboTag approach in mouse that allows deep-sequencing analysis of ribosome-bound mRNAs in the retinal ganglion cell axons of the developing and adult retinotectal(More)
The p34(SEI-1) oncoprotein is involved in a transcriptional regulation, cell cycle regulation, apoptosis, development and many other important cellular functions. Our present study suggests that p34(SEI-1) can promote metastasis by enhancing migration and invasion of cancer cells. Consistently, p34(SEI-1) expression was found to be increased as the tumor(More)
Blood vessels supply oxygen and nutrients throughout the body, and the formation of the vascular network is under tight developmental control. The efficient in vivo visualization of blood vessels and the reliable quantification of their complexity are key to understanding the biology and disease of the vascular network. Here, we provide a detailed method to(More)
OBJECTIVE Angiogenesis, the process of building complex vascular structures, begins with sprout formation on preexisting blood vessels, followed by extension of the vessels through proliferation and migration of endothelial cells. Based on the potential therapeutic benefits of preventing angiogenesis in pathological conditions, many studies have focused on(More)
