CCN family, a group of six extracellular matrix-associated proteins, plays an important role in fibrosis. WISP3 has addressed as a pro-fibrotic molecule in the development of human lung fibrosis. However, whether WISP3 involved in the activation and proliferation of renal fibroblast, and ultimately inhibited fibroblast-myofibroblast transdifferentiation remained unknown. Herein, we found that down-regulated WISP3 was involved in the fibrogenesis of rat renal NRK-49F cells induced by transforming growth (TGF-β1), which was further confirmed in a rat renal fibrosis induced by unilateral ureteral obstruction (UUO)...

BACKGROUND: Hepatocellular Carcinoma (HCC) is the most common primary carcinoma of the liver, which mainly metastasizes through the portal vein system. CASE PRESENTATION: Here, we report an extremely rare case in which HCC metastasized to the capsule of an undescended testis in the right inguinal area of the patient. A tumor approximately 8.8 × 7.0 cm in size was found in the patient's liver during a health check-up. Initially, it was considered a metastatic tumor because the patient was found to have cryptorchidism, which had been left untreated before he presented to our hospital...

Involvement of matrix metalloproteinases (MMPs) in the pathogenesis of urothelial carcinoma elects them to be sensitive marker for clinical and prognostic implications. MMPs regulate tumor growth and invasion by inducing epithelial-to-mesenchymal transition (EMT) which is characterized by the complex reprogramming of epithelial cells and ultimately bring about major changes in the structural organization of bladder urothelium. The present study has been undertaken to evaluate the clinical relevance of MMPs in two distinct types of bladder cancer disease...

The human fyn-related kinase (FRK) is a non-receptor tyrosine kinase known to have tumor suppressor activity in breast cancer cells. However, its mechanism of action has not been fully characterized. We generated FRK-stable MDA-MB-231 breast cancer cell lines and analyzed the effect on cell proliferation, migration, and invasiveness. We also used kinome analysis to identify potential FRK-regulated signaling pathways. We employed both immunoblotting and RT-PCR to identify/validate FRK-regulated targets (proteins and genes) in these cells...

Stromal carcinoma-related fibroblasts (CAFs) are the main type of non-immune cells in the tumor microenvironment (TME). CAFs interact with cancer cells to promote tumor proliferation. Long non-coding RNAs (lncRNAs) are known to regulate cell growth, apoptosis, and metastasis of cancer cells, but their role in stromal cells is unclear. Using RNA sequencing, we identified a stromal lncRNA signature during the transformation of CAFs from normal fibroblasts (NFs) in oral squamous cell carcinoma (OSCC). We uncovered an uncharacterized lncRNA, FLJ22447, which was remarkably up-regulated in CAFs, referred to LncRNA-CAF (Lnc-CAF) hereafter...

We present a 27-year-old male patient with neurofibromatosis type 2 (NF2), facial palsy, and lagophthalmos following acoustic neuroma removal and an impressing vascularized corneal tumor, which was excised. Histology showed a fibrous tumor with small vessels, and immunohistochemistry was positive for vimentin and negative for smooth muscle actin, S100, and GFAP. We assume a corneal myofibroma (keloid), which in this case rather represents a reactive lesion. This entity has not been described before in NF2 or in facial palsy-associated lagophthalmos in general...

Breast cancer is a heterogeneous disease that can be classified into several molecular intrinsic subtypes according to hormone markers, including estrogen receptor, progesterone receptor and human epidermal growth factor receptor-2. Breast cancer cases with different hormone status vary with respect to patient morbidity, metastasis organotropism and disease progression. It is well known that the most preferential relapse site of breast cancer is in the bone, but the metastatic incidence is markedly higher in hormone receptor-positive cancer compared with that in hormone receptor-negative cancers...

It has been reported that the epithelial-mesenchymal transition (EMT) plays an important role in hepatocellular carcinoma (HCC). However, the relationship between the insulin-like growth factor-1 (IGF-1) and EMT of HCC was not fully elucidated. In the present work, we found that the expression of N-cadherin, Vimentin, Snail1, Snail2, and Twist1 was positively associated with IGF-1R expression, while E-cadherin expression was negatively associated with IGF-1 expression in human HCC samples. Furthermore, we observed that IGF-1 up-regulated the expression of N-cadherin, Vimentin, Snail1, Snail2 and Twist1, and down-regulated the expression of E-cadherin...

Chemotherapy is one of the main approach for ovarian cancer. Cancer stem cells (CSCs) escape chemotherapy and lead to chemoresistance. We previously demonstrated that cordycepin (Cd) inhibited metastasis in human ovarian carcinoma cells, the aim of this study is to investigate the effects of Cd on ovarian cancer stemness. TGF-beta was used to induce chemoresistance of chemotherapeutic agent cisplatin in SKOV-3 ovarian cancer cells. After treating with 100 μM of Cd, cell viability, the percentage of cancer stem cells, and the levels of matrix metalloproteinases (MMPs) were decreased in TGF-beta-induced SKOV-3 cells...
