TLDR
Transfectants of HeLa and DLD-1 cells ectopically expressing galectin-7 were found to be more susceptible to apoptosis than control transfectants and this protein is a pro-apoptotic protein that functions intracellularly upstream of JNK activation and cytochrome c release.About:

Galectins as modulators of tumour progression
TL;DR: Current research indicates that galectins have important roles in cancer; they contribute to neoplastic transformation, tumour cell survival, angiogenesis and tumour metastasis, and might have a key role helping tumours to escape immune surveillance.

TL;DR: In this paper, a frontal affinity chromatography (FAC) was used to quantitatively analyze the interactions at 20 °C between 13 galectins including 16 CRDs originating from mammals, chick, nematode, sponge, and mushroom, with 41 pyridylaminated (PA) oligosaccharides.

Galectins: structure, function and therapeutic potential.
TL;DR: Current research indicates that galectins play important roles in diverse physiological and pathological processes, including immune and inflammatory responses, tumour development and progression, neural degeneration, atherosclerosis, diabetes, and wound repair, and may be a therapeutic target or employed as therapeutic agents for inflammatory diseases, cancers and several other diseases.

Galectins and their ligands: amplifiers, silencers or tuners of the inflammatory response?
Gabriel A. Rabinovich,Linda G. Baum,Nicola Tinari,Roberto Paganelli,Clara Natoli,Fu-Tong Liu,Stefano Iacobelli +6 more
TL;DR: The current wealth of new information promises a future scenario in which individual members of the galectin family or their ligands will be used as powerful anti-inflammatory mediators and selective modulators of the immune response.

A novel assay for apoptosis. Flow cytometric detection of phosphatidylserine expression on early apoptotic cells using fluorescein labelled Annexin V.
TL;DR: The Annexin V assay offers the possibility of detecting early phases of apoptosis before the loss of cell membrane integrity and permits measurements of the kinetics of apoptotic death in relation to the cell cycle.
Journal ArticleDOI
Signal transduction by the JNK group of MAP kinases.
TL;DR: This review will focus on the JNK group of MAP kinases, which are characterized by the sequence TEY and the two stress-activatedMAP kinases: p38 with the sequence TGY, and the c-Jun NH2-terminal kinases (JNK) with the sequences TPY.

TL;DR: A potent peptide aldehyde inhibitor has been developed and shown to prevent apoptotic events in vitro, suggesting that apopain/CPP32 is important for the initiation of apoptotic cell death.

Normal keratinization in a spontaneously immortalized aneuploid human keratinocyte cell line.
TL;DR: The characteristics of the HaCaT cell line clearly document that spontaneous transformation of human adult keratinocytes can occur in vitro and is associated with sequential chromosomal alterations, though not obligatorily linked to major defects in differentiation.

TL;DR: In this paper, a gene was identified that directed the expression of antigen MZ2-E on a human melanoma cell line, which belongs to a family of at least three genes.
