In molecular biology, TP53 target 1 (non-protein coding), also known as TP53TG1, is a long non-coding RNA. Its expression is induced by p53 under conditions of cellular stress.[1]

The TP53-inducible glycolysis and apoptosis regulator (TIGAR) also known as fructose-2,6-bisphosphatase TIGAR is an enzyme that in humans is encoded by the TIGAR gene (previously C12orf5). TIGAR is a recently discovered enzyme that primarily functions as a regulator of glucose breakdown in human cells. In addition to its role in controlling glucose degradation, TIGAR activity can allow a cell to carry out DNA repair, and the degradation of its own organelles. Finally, TIGAR can protect a cell from death. Since its discovery in 2005 by Kuang-Yu Jen and Vivian G. Cheung, TIGAR has become of particular interest to the scientific community thanks to its active role in many cancers. Normally, TIGAR manufactured by the body is activated by the p53 tumour suppressor protein after a cell has experienced a low level of DNA damage or stress. In some cancers, TIGAR has fallen under the control of other proteins. The hope is that future research into TIGAR will provide insight into new ways to treat cancer. This gene is regulated as part of the p53 tumor suppressor pathway and encodes a protein with sequence similarity to the bisphosphate domain of the glycolytic enzyme that degrades fructose-2,6-bisphosphate. The protein functions by blocking glycolysis and directing the pathway into the pentose phosphate shunt. Expression of this protein also protects cells from DNA damaging reactive oxygen species and provides some protection from DNA damage-induced apoptosis. The 12p13.32 region that includes this gene is paralogous to the 11q13.3 region.
TP53 target 3D is a protein that in humans is encoded by the TP53TG3D gene.
In molecular biology, TP53 target 1 (non-protein coding), also known as TP53TG1, is a long non-coding RNA. Its expression is induced by p53 under conditions of cellular stress.
p53, also known as tumor protein p53, TP53, cellular tumor antigen p53 (UniProt name), or transformation-related protein 53 (TRP53) is a regulatory transcription factor protein that is often mutated in human cancers. The p53 proteins (originally thought to be, and often spoken of as, a single protein) are crucial in vertebrates, where they prevent cancer formation. As such, p53 has been described as "the guardian of the genome" because of its role in conserving stability by preventing genome mutation. Hence TP53 is classified as a tumor suppressor gene. The TP53 gene is inactivated in a majority (>50%) of human cancer cases. This can be caused by any various factors, including mutations in the gene, epigenetic events, or interactions with other proteins. This association indicates that the TP53 gene plays a crucial role in preventing cancer formation. TP53 gene encodes proteins that bind to DNA and regulate gene expression to prevent mutations of the genome. In addition to the full-length protein, the human TP53 gene encodes at least 12 protein isoforms. Comparative genomic studies found pathogenic mutations absent in some Neanderthal populations, while modern humans exhibit an expansion of over 1,000 mutated variations. Evidence suggests that the vast majority of these protein-coding variants arose very recently in human history, specifically concentrated within a window of 5,000 to 10,000 years ago.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
