In response to genotoxic stress, Hzf forms an autoregulatory loop with the p53 tumor suppressor, binding directly to its DNA‐binding domain to favor the transactivation of genes involved in cell‐cycle arrest over those triggering apoptosis. This regulatory mechanism ensures that, upon DNA damage, the balance shifts toward reversible cell-cycle arrest and DNA repair rather than cell death."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nMoreover, Hzf plays critical roles in several specialized cellular contexts. It is essential for proper megakaryopoiesis and hemostasis by regulating the synthesis or packaging of alpha‐granule substances in platelets, and it promotes adipocyte differentiation by enhancing the translation of key factors such as C/EBPα. In neuronal cells, Hzf controls the dendritic localization of specific mRNAs—including that of the inositol 1,4,5‐trisphosphate receptor—thereby influencing synaptic plasticity and motor learning. In addition, Hzf collaborates with proteins like DISC1 to mediate the dendritic transport of mRNAs that are vital for synaptic function."}, {"type": "fg", "children": [{"type": "fg_fs", "start_ref": "3", "end_ref": "7"}]}, {"type": "t", "text": "\n"}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nDistinct from these functions, the long noncoding RNA LINC01783 has been identified as an oncogenic factor in tongue squamous cell carcinoma (TSCC).

Mechanistically, LINC01783 acts as a competitive endogenous RNA by sponging miR-199b-5p, thereby reducing the miRNA’s inhibitory effects on downstream targets and contributing to oncogenic progression.
