Professionalism is a core competency for all healthcare professionals and is a subject of great interest within the academic community due to its vital importance in delivering the highest quality patient care. Despite this, professionalism remains difficult to define, teach and assess. The potential use of anatomy education in teaching professionalism has been increasingly highlighted within the literature, but still remains an underutilised tool in medical education. Therefore, this practical guide offers evidence-based practical points for successfully incorporating professionalism within a dissection-based anatomy course delivered to undergraduate medical students.[This corrects the article on p. 2621 in vol. 10, PMID 32905506.].Breast cancer remains a complex disease resulting in high mortality in women. A subset of cancer stem cell (CSC)-like cells expressing aldehyde dehydrogenase 1 (ALDH1) and SOX2/OCT4 are implicated in aggressive biology of specific subtypes of breast cancer. Targeting these populations in breast tumors remain challenging. We examined xenografts from three poorly studied triple negative (TN) breast cancer cells (MDA-MB-468, HCC70 and HCC1806) as well as HMLEHRASV12 for stem cell (SC)-specific proteins, proliferation pathways and dual-specific phosphatases (DUSPs) by quantitative real-time PCR (qRT-PCR), immunoblot analysis and immunohistochemistry. We found that pERK1/2 remained suppressed in TN xenografts examined at various stages of growth, while the levels of pp38 MAPK and pAKT was upregulated. We found that DUSP was involved in the suppression of pERK1/2, which was MEK1/2 independent. Our in vitro assays, using HMLEHRASV12 xenografts as a positive control, confirmed increased phosphatase activity that specthat subsets of TN breast cancers with MEK1/2 independent reduced pERK1/2 levels will respond less to MEK1/2 inhibitors, thereby questioning their therapeutic efficacy. Our study also demonstrates context-dependent DUSP9-mediated reduced pERK1/2 levels could influence stem cell-like traits in TN breast tumors. Therefore, targeting DUSP9 could be an attractive target for improved clinical outcome in a subset of basal-like breast cancers.A newly diagnosed or recurrent Glioblastoma multiforme (GBM) can be treated with Tumor-treating fields (TTFields), an emerging type of alternative electric field-based therapy using low-intensity electric fields. TTFields have a penchant to arrest mitosis, eventually leading to apoptosis. Therefore, it is regarded as a potential anticancer therapy. However, in this study, we confirmed the combined efficacy of sorafenib and TTFields to improve the treatment efficiency of malignant GBM. Experimentation revealed the ability of sorafenib to decrease the signal transducer and activator of transcription 3 (STAT3) and this inhibition increased the sensitivity of TTFields in preventing tumor expansion. It was found that both combinatorial as well as monotherapy aimed to inhibit or reduce the level of STAT3, but the extent was different and based upon the reaction conditions. This drug is also capable of arresting multiple kinase pathways along with STAT3-related proteins (Mcl-1 and Survivin). STAT3 silencing can also be accomplished by RNA interference and can increase the TTFields-sensitizing effect of sorafenib. Super-TDU solubility dmso If the effects are reversed and gene regulating STAT3 is expressed more, it annihilates the effects of treatment. Moreover, sorafenib plus TTFields significantly inhibited xenograft tumor growth and combinatorial treatment reduced STAT3 expression more effectively in vivo. These in vitro and in vivo results indicate that sorafenib tends to sensitize GBM cells to TTFields-induced apoptosis by inhibiting STAT3.Despite significant advances, skin cutaneous melanoma (SKCM) is a common life-threatening cancer worldwide. Recently, pseudogenes have been discovered to be functional in many physiological processes and the pathogenesis of various diseases, including cancer. However, their relevance to SKCM remains largely unknown. In this study, seven upregulated pseudogenes were identified based on TCGA data. Among them, MTND4P12 was negatively correlated with the overall survival of SKCM patients. After constructing a pseudogene-miRNA-mRNA regulatory network, MTND4P12 was found to regulate the expression of oncogene AURKB by serving as a ceRNA. Both genetic and chemical inhibition of AURKB reduced viability and induced apoptosis of melanoma cells. Interestingly, DNA repair pathway seems to be involved in the anti-tumor effect of AURKB inhibition. Indeed, a synergistic therapeutic effect of AURKB inhibition and PARP inhibitor was confirmed both in vitro and in vivo. In conclusion, AURKB plays an oncogenic role and is a novel therapeutic target in SKCM. The combination of AURKB inhibition and PARP inhibitor has a synergistic effect, representing a promising treatment for SKCM.Breast cancer (BC) is the most common female malignancy worldwide, and 70% of which are estrogen receptor α (ERα) positive. Endocrine treatment, such as tamoxifen, is a primary adjuvant therapy for patients with ER-positive BC. However, some patients will develop acquired resistance following long-time treatment. Further research on estrogen signaling is important to improve the therapy of these patients. In this study, we report that the E3 ubiquitin ligase tripartite motif 8 (TRIM8) acts as a novel regulator of ERα signaling. TRIM8 is downregulated in BC and is associated with poor prognosis. In addition, the protein level of TRIM8 is negatively correlated with ERα. RNA sequencing revealed that estrogen signaling maybe a potential target of TRIM8. Moreover, knockdown of TRIM8 can significantly enhance BC cell proliferation and migration both in vitro and in vivo. And this effect can be reversed by ERα depletion. Further mechanistic studies showed that TRIM8 interacts with AF1 domain of ERα via its RING domain in the cytoplasm and increases poly-ubiquitination of the ERα protein. In conclusion, our study reveals an interesting post-translational mechanism between ERα and TRIM8 in ER-positive BC, which suggests that TRIM8 may be a potential therapeutic target in the treatment of BC.
