Objective: The aim of this study was to determine the markers of prognosis in metastatic inflammatory breast cancer (IBC).
Subjects And Methods: The prognostic value of patients' clinical characteristics and expression of c-erbB-2, p53, Ki-67, ER and PgR were assessed in the 45 patients with IBC who had developed distant metastasis. Immunohistochemical methods were used to detect the expression of c-erbB-2, p53, Ki-67, ER and PgR in surgical resection specimens of the patients' primary tumor.
Results: The median overall survival (OS) measured from the diagnosis of metastatic disease was 23 months. In the univariate analysis, p53 protein accumulation and the presence of visceral metastasis were predictive of poor survival (p = 0.01 and 0.003, respectively). In the multivariate analysis, accumulation of p53 protein and the presence of visceral metastasis correlated with OS (p = 0.02 and 0.008, respectively).
Conclusion: In metastatic IBC, accumulation of p53 protein and presence of visceral metastasis are independent prognostic factors for OS. Established prognostic factors in non-IBC patients such as patient age, histologic grade, hormone receptor status and c-erbB-2 status did not have independent significance in IBC in this study.

High-risk human papillomavirus E6 oncoprotein is a model system for the recognition and degradation of cellular p53 tumor suppressor protein. There remains a gap in the understanding of the ubiquitin transfer reaction, including placement of the E6AP catalytic HECT domain of the ligase concerning the p53 substrate and how E6 itself is protected from ubiquitination. We determined the cryoelectron microscopy (cryo-EM) structure of the E6AP/E6/p53 complex, related the structure to in vivo modeling of the tri-molecular complex, and identified structural interactions associated with activation of the ubiquitin ligase function.

Objective: Colorectal Cancer (CRC) has attracted much attention due to its high mortality and morbidity. Cordycepin, also known as 3'-deoxyadenosine (3'-dA), exhibits many biological functions, including antibacterial, anti-inflammatory, antiviral, anti-tumor, and immunomodulatory effects. It has been proven to show anticancer activity in both laboratory research studies and living organisms.

Idiopathic pulmonary fibrosis (IPF) is a debilitating, incurable, and life-threatening disease that lacks effective therapy. The overexpression of phosphodiesterase 10A (PDE10A) plays a vital role in pulmonary fibrosis (PF). However, the impact of selective PDE10A inhibitors on the tumor growth factor-β (TGF-β)/small mother against decapentaplegic (Smad) signaling pathway remains unclear.

Tumor metastasis is a difficult clinical problem to solve due to tumor heterogeneity and the emergence of antiapoptotic clones driven by tumor evolution. Clinical combination chemotherapy remains a standard treatment for solid metastasis tumors but with worse treatment efficiency. It is worth exploring a high-efficiency and low-side-effect therapeutic method to solve solid metastases.
