Immunofluorescent analysis of LIN28 (green) in Hela cells. Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 5-10 minutes at room temperature and blocked with 3% BSA-PBS for 30 minutes at room temperature. Cells were probed with a LIN28 polyclonal antibody (Product # PA1-096 ) at a dilution of 1:100 and incubated overnight in a humidified chamber. Cells were washed with PBST and incubated with a DyLight-conjugated secondary antibody for 45 minutes at room temperature in the dark. F-actin (red) was stained with a fluorescent phalloidin and nuclei (blue) were stained with DAPI. Images were taken at a 60X magnification.

LIN28A/B are expressed in various cancers and ES cells. LIN28 is a cytoplasmic protein, that acts as a 'translational enhancer', driving specific mRNAs to polysomes and thus increasing the efficiency of protein synthesis. LIN28 is a negative regulator of microRNA (miRNA) biogenesis by specifically binding the precursor of let-7 (pre-let-7). Let-7 miRNAs have been implicated in repression of oncogenes such as ras and myc. LIN28 expression decreases during differentiation of ES cells or upon induction of neuronal differentiation by retinoic acid.
