Two New Species of Sect. From Sichuan, China.

In groups undergoing rapid radiations, species delimitation among phylogenetically close sister lineages has long been a challenge. During plant surveys in northwestern Sichuan, we unexpectedly discovered two putative new species of that are morphologically similar yet distinct from each other. These species resemble , which has been assigned to sect.

[The regulation of anoikis in tumor invasion and metastasis].

As a barrier to metastasis of cancer, cells that lost contact with the neighbouring cells or extracellular matrix(Extracellular matrix, ECM) will be subjected to apoptosis. This cell death process has been termed "anoikis". When normal epithelial cells or solid tumor cells without metastatic potential detach from the primary site, and then enter into the circulatory system, the anoikis mechanism will be activated.
