YY2-CYP51A1 signaling suppresses hepatocellular carcinoma progression by restraining de novo cholesterol biosynthesis.

Lipid accumulation is a frequently observed characteristic of cancer. Lipid accumulation is closely related to tumor progression, metastasis, and drug resistance; however, the mechanism underlying lipid metabolic reprogramming in tumor cells is not fully understood. Yin yang 2 (YY2) is a C2H2‑zinc finger transcription factor that exerts tumor-suppressive effects.

p52-ZER6/IGF1R axis maintains cancer stem cell population to promote cancer progression by enhancing pro-survival mitophagy.

Cancer stem cells (CSCs), which are distinct subpopulations of tumor cells, have a substantially higher tumor-initiating capacity and are closely related to poor clinical outcomes. Damage to organelles can trigger CSC pool exhaustion; however, the underlying mechanisms are poorly understood. ZER6 is a zinc-finger protein with two isoforms possessing different amino termini: p52-ZER6 and p71-ZER6.

YY2/BUB3 Axis promotes SAC Hyperactivation and Inhibits Colorectal Cancer Progression via Regulating Chromosomal Instability.

Spindle assembly checkpoint (SAC) is a crucial safeguard mechanism of mitosis fidelity that ensures equal division of duplicated chromosomes to the two progeny cells. Impaired SAC can lead to chromosomal instability (CIN), a well-recognized hallmark of cancer that facilitates tumor progression; paradoxically, high CIN levels are associated with better therapeutic response and prognosis. However, the mechanism by which CIN determines tumor cell survival and therapeutic response remains poorly understood.

YY2/PHGDH axis suppresses tumorigenesis by inhibiting tumor cell de novo serine biosynthesis.

Metabolic reprogramming is one of the key features of tumors facilitating their rapid proliferation and adaptation to harsh microenvironments. Yin Yang 2 (YY2) has recently been reported as a tumor suppressor downregulated in various types of tumors; however, the molecular mechanisms underlying its tumor-suppressive activity remain poorly understood. Furthermore, the involvement of YY2 in tumor cell metabolic reprogramming remains unclear.
