OCT4, also known as POU5F1 (
POU domain class 5 transcription factor 1
), is a transcription factor that acts as a master regulator of pluripotency in embryonic stem cells and is one of the reprogramming factors required for generating induced pluripotent stem cells. The human OCT4 encodes three isoforms, OCT4A, OCT4B, and OCT4B1, which are generated by alternative splicing. Currently, the functions and expression patterns of OCT4B remain largely unknown in malignancies, especially in human glioblastomas. Here, we demonstrated the function of OCT4B in human glioblastomas. Among the isoform of OCT4B, OCT4B-190 (OCT4B
19kDa
) was highly expressed in human
glioblastoma
stem cells and
glioblastoma
cells and was mainly detected in the cytoplasm rather than the nucleus. Overexpression of OCT4B
19kDa
promoted colony formation of
glioblastoma
cells when grown in soft agar culture conditions. Clinical data analysis revealed that patients with gliomas that expressed OCT4B at high levels had a poorer prognosis than patients with gliomas that expressed OCT4B at low levels. Thus, OCT4B
19kDa
may play a crucial role in regulating cancer cell survival and adaption in a rigid environment.
