Silk genes and silk gene expression in the spider Tengella perfuga (Zoropsidae), including a potential cribellar spidroin (CrSp).

Most spiders spin multiple types of silk, including silks for reproduction, prey capture, and draglines. Spiders are a megadiverse group and the majority of spider silks remain uncharacterized. For example, nothing is known about the silk molecules of Tengella perfuga, a spider that spins sheet webs lined with cribellar silk.

Increases in quantitative D-dimer levels correlate with progressive disease better than circulating tumor cell counts in patients with refractory prostate cancer.

Changes in quantitative D-dimer levels, circulating tumor cell (CTC) counts, and prostate-specific antigen (PSA) levels were measured in 28 patients with refractory castration-resistant prostate cancer to assess their concordance during the course of therapy and their relationship with risk of progressive disease. A significant correlation was identified between changes in PSA and both CTC counts and D-dimer levels (r = 0.67 and 0.

Dramatically elevated circulating tumor cell numbers in a patient with small cell neuroendocrine carcinoma of the prostate.

Detection of circulating tumor cells in whole blood is a useful prognostic tool for patients with castration-resistant prostate cancer, as well as for patients with metastatic breast cancer and colorectal carcinoma. In this report, we present the case of a patient with neuroendocrine small cell prostate cancer with normal prostate-specific antigen levels throughout the course of disease but who had markedly elevated circulating tumor cells, as detected with the CellSearch (Veridex) system.
