Antitumor virotherapy using syngeneic or allogeneic mesenchymal stem cell carriers induces systemic immune response and intratumoral leukocyte infiltration in mice

In this study we use our virotherapy Celyvir with syngeneic and allogeneic mouse mesenchymal stem cells to determine their antitumor efficacy in a C57BL/6 murine adenocarcinoma model. Adoptive transfer of splenocytes from treated mice to new tumor-bearing mice followed by a secondary adoptive transfer to a third group was performed. Similar reduction of tumor growth and systemic activation of the innate and adaptive immune system was observed in groups treated with syngeneic or allogeneic mesenchymal stem cells loaded with ICOVIR-5. Moreover, a different pattern of infiltration was observed by immunofluorescence in Celyvir-treated groups. While non-treated tumors presented higher density of infiltrating immune cells in the periphery of the tumor, both syngeneic and allogeneic Celyvir-treated groups presented higher infiltration of CD45+  cells in the core of the tumor. Therefore, these results suggest that syngeneic and allogeneic Celyvir induce systemic activation of the immune system, similar antitumor effect and a higher intratumoral infiltration of leukocytes.

Additionally, Ajuba contains both nuclear export sequences (NES) and nuclear localization sequences (NLS), which enable Ajuba shuttle between the cytoplasm and the nucleus. Thus, Ajuba can act as a versatile scaffold participating in assembly of variety of protein complexes to execute multiple cellular functions including cell adhesion, moti...

Bcl-XL is one of the key regulators of apoptosis that can also regulate other important cellular functions. Bcl-XL is overexpressed in many cancers, and its inhibitors have shown good therapeutic effects. Bcl-XL interacts with Beclin 1, a key factor regulating autophagy.Bcl-XL is essential for the survival of neurons and plays protective ro...

ConclusionsThis is the first sun protection accreditation program developed for Spanish schools. Studies are needed to evaluate how this program is received and how it affects students’ sun protection behaviors.ResumenIntroducciónLa exposición solar en la infancia es el principal factor de riesgo para el desarrollo de cáncer de piel en la vida adulta. Las intervenciones basadas en programas y políticas de fotoprotección escolar han demostrado ser las estrategias más eficaces y coste-efectivas para la prevención del cáncer de piel.ObjetivosElaborar un modelo de c...

Authors: Zhang Y, Tang M, Wang XG, Gu JH, Zhou LN, Jin J, Li P, Wang LQ, Chen MB Abstract BACKGROUND: interleukin-37 (IL-37) is as a natural suppressor of the innate inflammatory and immune responses. It has also been reported to be involved in carcinogenesis and metastasis. The present case-control study was designed to investigate the role of serum levels of IL-37 in patients with gastric cancer. METHODS: serum IL-37 levels were determined using the enzyme-linked immunosorbent assay in 180 patients diagnosed with gastric cancer and 100 healthy controls. The association between IL-37 levels and clinical factor...

Authors: Villar Lucas C, Hernando Martín M, Álvarez-Cuenllas B Abstract Juvenile polyps are hamartomatous lesions, usually unique, which appear at an early age. They are usually located in the rectosigmoid junction and are not thought to imply a higher risk of colorectal cancer. Here we report a case of signet ring cell (SRC) carcinoma in this type of lesion. PMID: 31718199 [PubMed - as supplied by publisher]

CONCLUSION: The various evaluation methods for predicting a pCR after PCRT show a predictive sensitivity of 0.15-0.41 for primary tumors and 0.52-0.88 for lymph nodes. Endoscopy is a relatively superior modality for predicting the pCR of the primary tumor of LARC patients. PMID: 31726004 [PubMed]

This study included 24 patients (18 females) with a median age of 51.5 years (range, 21-68 years). Ten cases were symptomatic and 14 were asymptomatic. Cysts were retrorectal in 21 patients. Cysts were below the coccyx level in 16 patients, opposite the coccyx in 6, and above the coccyx in 2. Cysts were supralevator in 5 patients, had a supra- and infralevator extension in 18 patients, and were infralevator in 1. Ten patients were managed using an anterior laparoscopic approach, 11 using a posterior approach, and 3 using a combined approach. Mean cyst size was 5.5 ± 2.7 cm. Postoperative complications were Clavien-D...

CONCLUSION: Surgical oncologists consider the patient's condition and postoperative course rather than high-risk factors to determine use of AC. Regardless of AC use, both the extent of surgery and the patient's subsequent status affected the survival rate in the high-risk group. None of the factors identified influenced survival rate in the low-risk group. PMID: 31726001 [PubMed]
