Non-melanoma skin cancers (NMSCs), including basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), are the most frequently diagnosed cancers in humans, however, their exact pathogenesis is not fully understood. In recent years, it has been hypothesized that the recently discovered Hippo pathway could play a detrimental role in cutaneous carcinogenesis, but no direct connections have been made. The Hippo pathway and its effector, YAP, are responsible for tissue growth by accelerating cell proliferation, however, YAP upregulation and overexpression have also been reported in numerous types of tumors. There is also evidence that disrupted YAP/Hippo signaling is responsible for cancer growth, invasion, and metastasis. In this short review, we will explore whether the Hippo pathway is an important regulator of skin carcinogenesis and if it could be a promising target for future therapies.

Background: Adipose-derived stem cell (ADSC) transplantation presents a promising approach for osteoporosis (OP) treatment. However, the therapeutic efficacy of ADSCs is hindered by low post-transplantation survival rates and limited capacities for adhesion, migration, and differentiation. Icariin (ICA), the primary active compound of Epimedium, has been shown to promote cell proliferation and induce osteogenic differentiation; however, its specific effects on ADSC osteogenesis and the mechanisms by which ICA enhances osteoporosis treatment through cell transplantation remain inadequately understood.

Background: The two-stage surgical technique of associated liver partition and portal vein ligation for staged hepatectomy (ALPPS) enables extensive liver resection and promotes future liver remnant regeneration (FLR), in part by inhibiting the Hippo signalling pathway. Its main effector, Yes-associated protein (YAP), has low intrinsic transcriptional activity and requires the transcription enhanced associated domain factor (TEAD) family members as cofactors for target gene transcription. We evaluated the intracellular localization and expression of TEAD1-4, hypothesized to regulate the activity of YAP and, consequently, liver regeneration.

Background: Depression constitutes a risk factor for osteoporosis, but underlying molecular and cellular mechanisms are not fully understood. MiRNAs influence gene expression and are carried by extracellular vesicles (EV), affecting cell-cell communication.
Aims: (1) Identify the difference in miRNA expression between depressed patients and healthy controls; (2) Analyze associations of these miRNAs with bone turnover markers; (3) Analyze target genes of differentially regulated miRNAs and predict associated pathways regarding depression and bone metabolism.
The TEAD family of transcription factors are best known as the DNA-binding factor in the Hippo pathway, where they act by interacting with transcriptional coactivators YAP and TAZ (YAP/TAZ). Despite the importance of the Hippo pathway, the in vivo functions of TEAD in mammals have not been well established. By comparing mouse mutants lacking TEAD1 and TEAD2 (TEAD1/2) to those lacking YAP/TAZ, we found that TEAD1/2 have both YAP/TAZ-dependent and -independent functions during ventral telencephalon development.

Its dysregulation is associated with abnormal expression of and -family genes. Recent works have highlighted the role of YAP1/TEAD activity in several cancers and its potential therapeutic implications.
