TIMP-1 triggers neutrophil extracellular trap formation in pancreatic cancer.

Cancer Res 2021 May 3. Epub 2021 May 3.

Institut fur Molekulare Immunologie und Experimentelle Onkologie, Klinikum rechts der Isar Technischen Universitat Munchen

Tumor-derived protein tissue inhibitor of metalloproteinases-1 (TIMP-1) correlates with poor prognosis in many cancers, including highly lethal pancreatic ductal adenocarcinoma (PDAC). The non-canonical signaling activity of TIMP-1 is emerging as one basis for its contribution to cancer progression. However, TIMP-1-triggered progression-related biological processes are largely unknown. Read More

Targeted dual inhibition of c-Met/VEGFR2 signalling by foretinib improves antitumour effects of nanoparticle paclitaxel in gastric cancer models.

J Cell Mol Med 2021 May 3. Epub 2021 May 3.

Department of Surgery, Indiana University School of Medicine, South Bend, IN, USA.

Elevated expression of multiple growth factors and receptors including c-Met and VEGFR has been reported in gastric adenocarcinoma (GAC) and thus provides a potentially useful therapeutic target. The therapeutic efficacy of foretinib, a c-Met/VEGFR2 inhibitor, was determined in combination with nanoparticle paclitaxel (NPT) in GAC. Animal studies were conducted in NOD/SCID mice in subcutaneous and peritoneal dissemination xenografts. Read More

Radical prostatectomy versus external beam radiation therapy for high-grade, clinically localized prostate cancer: Emulation of a target clinical trial.

Urol Oncol 2021 Apr 29. Epub 2021 Apr 29.

Harvard Medical School, Boston, MA; Division of Urologic Surgery, Beth Israel Deaconess Medical Center, Boston, MA. Electronic address:

Purpose: The comparative effectiveness of surgery and radiation therapy for high-grade, clinically localized prostate cancer remains a seminal, open question in urologic oncology, with no randomized controlled trials to inform management. We therefore emulated a hypothetical target clinical trial of radical prostatectomy (RP) versus external beam radiotherapy (EBRT) for high-grade, clinically localized prostate cancer.

Materials And Methods: We conducted observational analyses using the National Cancer Database from 2006-2015 to emulate a target clinical trial in men 55-69 years with cT1-3cN0cM0, PSA<20 ng/mL, Gleason 8 to 10 prostate adenocarcinoma treated with RP or 75 to 81 Gy EBRT with androgen deprivation therapy (EBRT+ADT).

Cancer Essential Genes Stratified Lung Adenocarcinoma Patients with Distinct Survival Outcomes and Identified a Subgroup from the Terminal Respiratory Unit Type with Different Proliferative Signatures in Multiple Cohorts.

Cancers (Basel) 2021 Apr 28;13(9). Epub 2021 Apr 28.

Graduate Institute of Medical Sciences, College of Medicine, Taipei Medical University, Taipei 11031, Taiwan.

: Heterogeneous features of lung adenocarcinoma (LUAD) are used to stratify patients into terminal respiratory unit (TRU), proximal-proliferative (PP), and proximal-inflammatory (PI) subtypes. A more-accurate subtype classification would be helpful for future personalized medicine. However, these stratifications are based on genes with variant expression levels without considering their tumor-promoting roles. Read More

NRF2 Enables EGFR Signaling in Melanoma Cells.

Int J Mol Sci 2021 Apr 7;22(8). Epub 2021 Apr 7.

Institute of Pathology, University of Würzburg, 97080 Würzburg, Germany.

Receptor tyrosine kinases (RTK) are rarely mutated in cutaneous melanoma, but the expression and activation of several RTK family members are associated with a proinvasive phenotype and therapy resistance. Epidermal growth factor receptor (EGFR) is a member of the RTK family and is only expressed in a subgroup of melanomas with poor prognosis. The insight into regulators of EGFR expression and activation is important for the understanding of the development of this malignant melanoma phenotype. Read More

Gastrointestinal-type chemotherapy prolongs survival in an atypical primary ovarian mucinous carcinoma: A case report.

World J Clin Cases 2021 Apr;9(11):2533-2541

Department of Radiation Oncology, The Affiliated Hospital of Qingdao University, Qingdao 266000, Shandong Province, China.

Background: Primary ovarian mucinous carcinoma is a rare histologic subtype of epithelial ovarian carcinoma and exhibits considerable morphologic overlap with secondary tumour. It is hard to differentiate primary from metastatic ovarian mucinous carcinoma by morphological and immunohistochemical features. Because of the histologic similarity between primary ovarian mucinous carcinoma and metastatic gastrointestinal carcinoma, it has been hypothesized that ovarian mucinous carcinomas might respond better to non-gynecologic regimens.

Characteristics of the PI3K/AKT and MAPK/ERK pathways involved in the maintenance of self-renewal in lung cancer stem-like cells.

Int J Biol Sci 2021 15;17(5):1191-1202. Epub 2021 Mar 15.

Department of Laboratory Medicine, the Affiliated Hospital of Southwest Medical University, Sichuan, China.

Lung cancer is the leading cause of cancer-related mortality worldwide due to its early asymptomatic and late metastasis. While cancer stem cells (CSCs) may play a vital role in oncogenesis and development of lung cancer, mechanisms underlying CSCs self-renewal remain less clear. In the present study, we constructed a clinically relevant CSCs enrichment recognition model and evaluated the potential functions of phosphatidylinositol 3-kinase (PI3K)/AKT pathway (PI3K/AKT) and mitogen-activated protein kinases/extracellular signal-regulated kinase (MAPK/ERK) pathways in lung cancer via bioinformatic analysis, providing the basis for in depth mechanistic inquisition.
