Pluripotency inducing Yamanaka factors: role in stemness and chemoresistance of liver cancer.

Expert Rev Anticancer Ther 2021 May 6:1-12. Epub 2021 May 6.

Molecular Cancer Genetics & Translational Research Laboratory, Section of Genetics, Department of Zoology, Aligarh Muslim University, Aligarh-Uttar Pradesh, India.

: Liver cancer is a major cause of mortality and is characterized by the transformation of cells into an uncontrolled mass of tumor cells with many genetic and epigenetic changes, which lead to the development of tumors. A small subpopulation of cell population known as Cancer Stem Cells (CSCs) is responsible for cancer stemness and chemoresistance. Yamanaka factors [octamer-binding transcription factor 4 (OCT4), SRY (sex-determining region Y)-box 2 (SOX2), kruppel-like factor 4 (KLF4), and Myelocytomatosis (MYC); OSKM] are responsible for cancer cell stemness, chemoresistance, and recurrence.

TFEB regulates pluripotency transcriptional network in mouse embryonic stem cells independent of autophagy-lysosomal biogenesis.

Cell Death Dis 2021 Apr 1;12(4):343. Epub 2021 Apr 1.

Department of Life Science, University of Seoul, Seoul, 130-743, Republic of Korea.

Transcription factor EB (TFEB), a well-known master regulator of autophagy and lysosomal biogenesis, is a member of the microphthalmia family of transcription factors (MiT family). Over the years, TFEB has been shown to have diverse roles in various physiological processes such as clearance for intracellular pathogenic factors and having developmental functions such as dendritic maturation, as well as osteoclast, and endoderm differentiation. However, in the present study, we propose a novel mechanism for TFEB governing pluripotency of mouse ESCs (mESCs) by regulating the pluripotency transcriptional network (PTN) in these cells.

Primary sex determination in birds depends on DMRT1 dosage, but gonadal sex does not determine adult secondary sex characteristics.

Proc Natl Acad Sci U S A 2021 Mar;118(10)

Division of Functional Genomics and Development, The Roslin Institute, Royal (Dick) School of Veterinary Studies, EH25 9RG Midlothian, United Kingdom.

In birds, males are the homogametic sex (ZZ) and females the heterogametic sex (ZW). Primary sex determination is thought to depend on a sex chromosome gene dosage mechanism, and the most likely sex determinant is the Z chromosome gene Doublesex and Mab-3-Related Transcription factor 1 (DMRT1). To clarify this issue, we used a CRISPR-Cas9-based monoallelic targeting approach and sterile surrogate hosts to generate birds with targeted mutations in the DMRT1 gene. Read More
