Poly(I:C) transfection induces a pro-inflammatory cascade in murine mammary carcinoma and fibrosarcoma cells.

RNA Biol 2022 Jan;19(1):841-851

Department of Medical Engineering, University of South Florida, Tampa, FL, USA.

Germline-encoded pattern recognition receptors [PRRs] in mammalian cells function in the detection of molecular patterns associated with pathogen invasion or cellular damage. A PRR subset is activated by the atypical presence and location of double-stranded RNA [dsRNA] or its synthetic analogue polyinosinic-polycytidylic acid [poly(I:C)], triggering pro-inflammatory signalling and death in many cell types. Poly(I:C) has been tested as a sole or combination cancer therapy in preclinical studies and clinical trials. Read More

Biopathology Department, Anticancer Center, Institut Bergonié, Bordeaux, France; INSERM U 1218, Action Unit, Bordeaux, France; University of Bordeaux, Talence, France.

This article provides an update of the recent developments in mesenchymal tumors of lower genital tract. We focus on the characterization of recurrent molecular events in certain genital stromal tumors, for instance angiomyofibroblastomas and superficial myofibroblastomas. Moreover, fusions involving Tyrosine-kinases receptors (NTRK, FRFR1, RET, COL1A1-PDGFB) have been demonstrated in an emerging group of mesenchymal tumors characterized by a fibrosarcoma-like morphology and a predilection for uterine cervix of premenopausal women.

Management of Myxofibrosarcoma and Undifferentiated Pleomorphic Sarcoma.

Surg Oncol Clin N Am 2022 Jul;31(3):419-430

Maria Sklodowska-Curie National Research Institute of Oncology, Sarcoma and Melanoma, Roentgena 5, 02-781 Warszawa, Poland. Electronic address:

Undifferentiated pleomorphic sarcoma (UPS) and myxofibrosarcoma (MFS) are genomically complex tumors commonly diagnosed in the extremities or trunk of elderly patients. They likely represent a spectrum of disease differentiated by myxoid stroma and curvilinear vessels observed in MFS but not in UPS. Limb-sparing surgery is the standard of care although the infiltrative nature of MFS mandates wider resection margins than are necessary for UPS. Read More

Rationale and design of ON-TRK: a novel prospective non-interventional study in patients with TRK fusion cancer treated with larotrectinib.

BMC Cancer 2022 Jun 7;22(1):625. Epub 2022 Jun 7.

Sylvester Comprehensive Cancer Center at University of Miami Miller School of Medicine, Miami, FL, USA.

Background: Tropomyosin receptor kinase (TRK) fusion proteins resulting from neurotrophic tyrosine receptor kinase (NTRK) gene fusions are rare primary oncogenic drivers in a wide array of tumors. Larotrectinib is a first-in-class, highly selective, central nervous system-active TRK inhibitor approved by the US Food and Drug Administration (FDA), European Medicines Agency (EMA), and over 40 countries for the treatment of TRK fusion solid tumors in adult and pediatric patients. Due to the rarity of TRK fusion cancer, larotrectinib was granted accelerated approval based on a relatively small number of patients enrolled in three early phase trials. Read More

Identification of a novel PHIP::BRAF gene fusion in infantile fibrosarcoma.

Genes Chromosomes Cancer 2022 Jun 7. Epub 2022 Jun 7.

de Duve Institute, Université catholique de Louvain, Brussels, Belgium.

Introduction: The ETV6::NTRK3 fusion is the most common gene alteration in infantile fibrosarcoma, a soft tissue tumor affecting patients under two years of age. Less frequently, these tumors harbor fusions of genes encoding other kinases, such as BRAF, which activates MEK in the mitogen-activated protein kinase pathway. The identification and characterization of these oncogenes are crucial to facilitate diagnosis, validate new treatments, and better understand the pathophysiology of these neoplasms. Read More

State Key Laboratory of Plant Physiology and Biochemistry, college of Biological Sciences, China Agricultural University, Beijing, 100193, China; School of Life Sciences, Institute of Life Science and Green Development, Hebei University, Baoding, 100193, China. Electronic address:

Plants adapt to their ever-changing environment via both positive and negative signals induced by environmental stimuli. Drought stress, for instance, induces the accumulation of the plant hormone abscisic acid (ABA), triggering ABA signaling transduction. However, the molecular mechanisms for switching between plant growth promotion and response to stress are still poorly understood. Read More

Dermatofibrosarcoma protuberans with unusual presentation in vulva.

Medicina (B Aires) 2022 ;82(3):441-444

División Ciencias de la Salud, Universidad del Norte, Barranquilla, Colombia.

Gynecological sarcomas are rare and their location in the vulva and vagina has an incidence of 5% of all malignant neoplasms in the female genital tract. We present the case of a 54-year-old patient with a diagnosis of dermatofibrosarcoma protuberans in the vulva, an infrequent pathology with less than 60 cases reported worldwide in this anatomical location. Clinically, it is locally aggressive, due to the proliferation of spindle cells with pleomorphism and frequent mitotic figures infiltrating the reticular dermis and subcutaneous cellular tissue, giving rise to variable size tumors with high local recurrence rates.

Division of Cell Matrix Biology & Regenerative Medicine, School of Biological Sciences, Faculty of Biology, Medicine and Health, Manchester Academic Health Sciences Centre, The University of Manchester, Manchester M13 9PT, UK.

Hydrogel biomaterials mimic the natural extracellular matrix through their nanofibrous ultrastructure and composition and provide an appropriate environment for cell-matrix and cell-cell interactions within their polymeric network. Hydrogels can be modified with different proteins, cytokines, or cell-adhesion motifs to control cell behavior and cell differentiation. Collagens are desirable and versatile proteins for hydrogel modification due to their abundance in the vertebrate extracellular matrix and their interactions with cell-surface receptors. Read More

Development of a potent small-molecule degrader against oncogenic BRAF protein that evades paradoxical MAPK activation.

Cancer Sci 2022 May 17. Epub 2022 May 17.

Division of Molecular Target and Gene Therapy Products, National Institute of Health Sciences, Kawasaki, Kanagawa, Japan.

BRAF mutations are frequently observed in melanoma and hairy-cell leukemia. Currently approved rapidly accelerated fibrosarcoma (RAF) kinase inhibitors targeting oncogenic BRAF V600 mutations have shown remarkable efficacy in the clinic, but their therapeutic benefits are occasionally hampered by acquired resistance due to RAF dimerization-dependent reactivation of the downstream MAPK pathway, which is known as paradoxical activation. There is also a concern that paradoxical activation of the MAPK pathway may trigger secondary cancer progression. Read More
