TL;DR: Galectin-3 is unique among the Galectin family of animal lectins in its biological activities and structure as mentioned in this paper, it possesses anti-apoptotic activity and its kinetics of precipitation are fast, on the order of seconds.

Journal ArticleDOI
TL;DR: The Q & A approach taken in this review lists a series of arguments in a stepwise manner to make the reader wonder why it is only a rather recent process that the concept of the sugar code has taken root in deciphering the mechanistic versatility of biological information storage and transfer.

Journal ArticleDOI
TL;DR: Human galectin-1 is a potent multifunctional effector that participates in specific protein-carbohydrate and protein-protein (lipid) interactions and its X-ray structure is determined, which provides the basis to define the structure of its ligand-binding pocket and to perform rational drug design.

Journal ArticleDOI
TL;DR: It is concluded that galectin-1 is a probable effector in the sialidase-dependent growth control in this system and functional divergence is revealed, most probably based on different topologies of presentation of homologous carbohydrate-binding sites.

TL;DR: To derive unequivocal diagnostic and prognostic information by immunohistochemistry on galectins with antagonistic impact on growth control and significant influence on cell adhesion, additional monitoring of these so far insufficiently studied family members is essential.
Abstract: Purpose: Knowledge about galectin expression by human tumor cells is mainly restricted to galectins-1 and -3. This study was conducted to define the gene expression pattern of all presently known human galectins in tumor cell lines of various histogenetic origin (galectinomics). Methods: The presence of mRNAs for human galectins-1, -2, -3, -4, -7, -8, and -9 was monitored by RT-PCR analyses in a panel of 61 human tumor cell lines of different origin (breast, colon, lung, brain, skin, kidney, urogenital system, hematopoietic system). Results: The validity of the technique was first confirmed by comparison of RT-PCR data with those obtained by Western blotting and cytofluorometry for galectins-1 and -3 in 18 cell lines. The following detection of a complex pattern of gene expression beyond commonly studied galectins-1 and -3 underscored the need for this fingerprinting. The most abundantly expressed message for a member of this lectin family was galectin-8 with 59 positive cell lines. With the exception of the tested lung tumors, galectin-1 and -3 transcripts were frequently expressed in the cell line panel with differences between individual cases. Positivity for galectins-2 and -4 was confined to a significant fraction of colorectal and neural tumors. Signals for galectin-9, the third known human tandem-repeat-type galectin besides -4 and -8, appeared in colorectal carcinoma cell lines with a frequency similar to that of galectin-4 but with inter-line differences. Its expression was restricted to lines of this tumor type, of the tested ovarian carcinoma, and hematopoietic malignancies. Conclusions: The results clearly demonstrate that human tumor cells express more mRNA species for galectins than those for galectins-1 and -3. To derive unequivocal diagnostic and prognostic information by immunohistochemistry on galectins with antagonistic impact on growth control and significant influence on cell adhesion, additional monitoring of these so far insufficiently studied family members is essential.

TL;DR: The fundamental concepts of enhanced permeability and retention effect (EPR) are revisited and the mechanisms proposed to enhance preferential "retention" in the tumor, whether using active targeting of nanoparticles, binding of drugs to their tumoral targets or the presence of tumor associated macrophages are explored.
