Article Abstract
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.

The fertile gonad includes cells of two distinct developmental origins: the somatic mesoderm and the germ line. How somatic and germ cells interact to develop and maintain fertility is not well understood. Here, using grafting experiments and transgenic reporter animals, we find that a specific part of the gonad-the germinal zone-acts as a sexual organizer to induce and maintain de novo germ cells and somatic gonads in the cnidarian .

Introduction: encodes an oligomeric BTB domain protein reported to inhibit neural crest formation through repression of Wnt/beta-catenin signalling, as well as transactivation by TFAP2. Heterozygous missense variants in the closely related paralogue KCTD1 cause scalp-ear-nipple syndrome.
Methods: Exome sequencing was performed on a two-generation family affected by a distinctive phenotype comprising a lipomatous frontonasal malformation, anosmia, cutis aplasia of the scalp and/or sparse hair, and congenital heart disease.

Cranial neural crest development is governed by positional gene regulatory networks (GRNs). Fine-tuning of the GRN components underlies facial shape variation, yet how those networks in the midface are connected and activated remain poorly understood. Here, we show that concerted inactivation of Tfap2a and Tfap2b in the murine neural crest, even during the late migratory phase, results in a midfacial cleft and skeletal abnormalities.
