Involvement of ribosomal protein L11 expression in sensitivity of gastric cancer against 5-FU.

5-Fluorouracil (5-FU) is widely used in the treatment of various types of solid cancer. Our study showed that ribosomal protein L11 (RPL11) was a crucial factor affecting sensitivity of gastric cancer to 5-FU, implying that RPL11 expression is a potential biomarker for predicting 5-FU sensitivity. Kaplan-Meier survival analysis indicated that high expression in gastric cancer patients treated with 5-FU was significantly associated with good prognosis.

Serotriflin, a CRISP family protein with binding affinity for small serum protein-2 in snake serum.

Habu (Trimeresurus flavoviridis) serum contains 3 small serum proteins (SSP-1, SSP-2, and SSP-3) with molecular masses of 6.5 to 10 kDa. Gel filtration analysis showed that all the SSPs exist in high molecular mass forms of approximately 60 kDa in the serum.

Identification of novel serum proteins in a Japanese viper: homologs of mammalian PSP94.

Three small serum proteins (SSP-1, -2, and -3), with molecular masses of 6.5-10kDa, were isolated from Habu (Trimeresurus flavoviridis) serum, and the amino acid sequences were determined by protein and cDNA analysis. Despite only limited sequence identity to any mammalian prostatic secretory protein of 94 amino acids (PSP94), all of the Cys residues in these SSPs were well conserved.
