- Bladder cancer (BLCA) is one of the common malignant tumors worldwide. Recent studies have shown that Transcription factor activating protein-2(TFAP2) family proteins plays a bidirectional regulatory role in the process of tumorigenesis versus evolution by regulating the expression of tumor associated genes. However, little is known about the function of distinct TFAP2s proteins in patient with BLCA. Formalin-fixed paraffin-embedded (FFPE) sample tissues and clinical data of 240 patients with bladder cancer were collected for immunohistochemical analysis. The Human Protein Atlas, Gene Expression Profiling Interactive Analysis (GEPIA), Shiny Methylation Analysis Resource Tool (SMART), Kaplan-Meier plotter, cBioPortal, Metascape, LinkedOmics, TIMER and CIBERSORT were utilized to analyze differential expression, prognostic value, genetic alteration and immune cell infiltration of TFAP2 family in patients with BLCA. Our study found that TFAP2 family proteins are generally expressed higher in BLCA tissues than in normal tissues. However, they show different trends in the growth, metastasis and survival prognosis of BLCA. TFAP2A and TFAP2C was associated with worse clinical stage and prognosis in BLCA patients, while TFAP2B, TFAP2D and TFAP2E showed the opposite trend. Importantly, the functions of the differentially expressed TFAP2s were primarily related to the developmental process, reproductive process, response to stimulus and immune system process, etc. Moreover, TFAP2 family was significantly correlated with the infiltration of six immune cell types and might regulate TAM polarization. TFAP2 family might be an important regulator of immune cell infiltration and a valuable prognostic biomarker in patients with BLCA. - Source: PubMed

Yuan FengSun YiDai Guang-ChengYao QiuZhou Yi-BingZang Ya-ChengLiu Xiao-LongXue Bo-Xin - The transcription factor family activator protein 2 (TFAP2) is vital for regulating both embryonic and oncogenic development. The TFAP2 family consists of five DNA-binding proteins, including TFAP2A, TFAP2B, TFAP2C, TFAP2D and TFAP2E. The importance of TFAP2 in tumor biology is becoming more widely recognized. While TFAP2D is not well studied, here, we mainly focus on the other four TFAP2 members. As a transcription factor, TFAP2 regulates the downstream targets directly by binding to their regulatory region. In addition, the regulation of downstream targets by epigenetic modification, posttranslational regulation, and interaction with noncoding RNA have also been identified. According to the pathways in which the downstream targets are involved in, the regulatory effects of TFAP2 on tumorigenesis are generally summarized as follows: stemness and EMT, interaction between TFAP2 and tumor microenvironment, cell cycle and DNA damage repair, ER- and ERBB2-related signaling pathway, ferroptosis and therapeutic response. Moreover, the factors that affect TFAP2 expression in oncogenesis are also summarized. Here, we review and discuss the most recent studies on TFAP2 and its effects on carcinogenesis and regulatory mechanisms. - Source: PubMed

Jin ChenLuo YuxiaoLiang ZhuLi XiKoĊat DamianZhao LinyongXiong Weixi - Alu elements are retroposons that invaded the primate genome and shaped its biology. Some Alus inserted recently and are polymorphic in the human population. It is these Alus that are being sought after in disease association studies and regulatory biology. Discovering polymorphic Alus in the human genome can open areas of new research in these fields. - Source: PubMed

Hamdi Hamdi KReddy SiddanaLaz NadaEltaher RenadKandell ZahraaMahmud TeifAlenazi LamiaHaroun BasheerHassan MohanadRagavendra Raju - The AP-2 transcription factor has been shown to play an important role in development, morphogenesis, apoptosis, cell-cycle control and has also been implicated in mammary oncogenesis. Here we report the cloning and characterization of a novel human transcription factor AP-2 like gene (TFAP2BL1), which is located on human chromosome 6p12.1-21.1. The TFAP2BL1 cDNA is 2076 base pairs in length, encoding a 452-amino acid polypeptide related to human Ap-2protein. TFAP2BL1 gene has significantly high homology to transcription factor AP-2 gene of human, mouse, chicken, sheep, fruit fly, and C. elegans at amino acid level. RT-PCR analysis shows its relatively high expression level in adult thymus, prostate, small intestine, skeletal muscle, placenta, brain, and testis tissues. - Source: PubMed
Cheng ChaoYing KangXu MingZhao WeiZhou ZongxiangHuang YanWang WeiXu JianZeng LiXie YiMao Yumin - AP-2 transcription factors are sequence-specific DNA-binding proteins expressed in neural crest and other tissues during mammalian development. Three mammalian genes, AP-2alpha, AP-2beta, and AP-2gamma, have been reported previously. A partial predicted AP-2 gene was identified in tandem with AP-2beta on human chromosome 6p12-p21.1. The orthologous mouse gene, which we named Ap-2delta, was identified from a fetal mouse head cDNA library. Northern analysis revealed two transcripts in embryonic and newborn mouse brain, with markedly higher steady-state levels in the former. The predicted Ap-2delta protein comprised 452 amino acids and was highly similar to other AP-2 proteins across the DNA-binding and dimerization domains. Ap-2delta formed homodimers and heterodimers in vitro, bound an optimized AP-2 consensus DNA sequence, and transactivated gene expression in eukaryotic cells. Ap-2delta dimers bound poorly to an AP-2 binding sequence from the human metallothionein IIa promoter in vitro, revealing a sequence specificity not previously observed among other AP-2 proteins. The PY motif and critical residues in the transactivation domain, which are highly conserved in the AP-2 family and believed necessary for transactivation, were divergent in Ap-2delta. The unique protein sequence and functional features of Ap-2delta suggest mechanisms, besides tissue-specific AP-2 gene expression, for specific control of target gene activation. - Source: PubMed
