Muscle invasive bladder cancer (MIBC) is an aggressive disease with high rates of local recurrence following radical cystectomy (RC). Currently, there are no clinically validated biomarkers to predict local only recurrence (LOR) and guide adjuvant treatment decisions. This pilot study evaluated the role of Ki-67, MRE11 and PD-L1 as predictive biomarkers for recurrence patterns in patients undergoing RC for MIBC.

Our institutional cystectomy database containing cases from 1992-2014 was queried for patients with local only recurrence (LOR), and case-matched to patients with distant recurrence (DR) and no recurrence (NR). Clinicopathological data were collected and a tissue microarray was analyzed for presence of Ki-67, MRE11, and PD-L1 using immunofluorescence and immunohistochemistry.

Pathologic specimens from 42 patients (18 NR, 16 LOR, and 8 DR) were reviewed. Compared to normal bladder tissue, tumors had increased expression of Ki-67 (p<0.01) and PD-L1 (p<0.05). High Ki-67 was associated with recurrence pattern (local vs. distant) on univariate analysis (p<0.05). Ki-67 cell density varied by recurrence type LOR (1354 cells/mm
), DR (557 cells/mm
) and NR (1111 cells/mm
) (p=0.034).

Our selected biomarkers could distinguish MIBC from normal bladder tissue but could not classify samples by recurrence pattern.

Integrin-targeting compounds have shown clinically significant benefits in many patients. Here, we examined the activity of millettocalyxin B, extracted from the stem bark of Millettia erythrocalyx, in lung cancer cells.

The viability of human lung cancer cells was investigated by the 3-(4,5-dimethylthiazol-2-yl)-2,5diphenyl tetrazoliumbromide (MTT) assay. Metabolism inhibitor Migration and invasion assays were performed. Phalloidin-rhodamine staining was used to determine the formation of filopodia. Western blot analysis and immunofluorescence staining were used to identify the signaling proteins involved in migration regulation.

Non-toxic concentrations (0-25 μM) of millettocalyxin B reduced migration and invasion of lung cancer A549 cells. Filopodia were significantly reduced in millettocalyxin B-treated cells. The migration regulatory proteins including integrin α5, active FAK, active Akt, and Cdc42 were significantly decreased in Millettocalyxin B-treated cells.

Our findings revealed a novel anti-migration and anti-invasion effects and the underlying mechanism of millettocalyxin B, which may be exploited for cancer treatment.

Lung cancer is the leading cause of cancer death worldwide. Cigarette smoke is the most important risk factor for cancer development. Growing evidence indicates that prolonged nicotine exposure is a potential factor associated with tumorigenesis. Here, the effect of prolonged nicotine exposure on A549 cells was investigated, using label-free quantitative proteomics.

Selection of an invasive subpopulation from the A549 cell line was performed to reveal the differential expression of proteins in relation to prolonged nicotine exposure, using Boyden chamber assays in combination with a proteomics approach.

One hundred proteins from the NicoA549-L5 subline showed significant change in expression compared to those from the A549-L5 subline and their A549 parental cell line. Heat shock protein, protein disulfide isomerase A3, profilin-1 and legumain were expressed at higher levels in A549 cells after prolonged nicotine exposure.

These aberrant proteins might serve as novel cancer biomarkers for cigarette smokers.

The enzyme-linked immunospot (ELISPOT) assay is a well-established method used to evaluate the strength of T cell-mediated immune activity, and accepted as a standard functional immunological assay. Cytokine activity is a novel parameter reflecting spot size and intensity, which has not been used in ELISPOT assay before.

In the present study, from 113 ELISPOT assay data derived from previous clinical trials with dendritic cell vaccines, both spot number count and cytokine activity data for IFN-γ secretion were obtained using an ELISPOT reader. Comparing the new parameter cytokine activity with the existing parameter spot number, the feasibility of cytokine activity was investigated.

There were no significant differences in sensitivity and specificity between spot number and cytokine activity among ELISPOT assay data from CMVpp65 and other antigen peptide-stimulated cytotoxic T lymphocytes.

Although cytokine activity is a novel parameter unreported so far, it did not show any advantages in the evaluation T cell immune responses compared to the existing spot number parameter.

A previous report showed that immune complex-ceruloplasmin (CP) in urine is associated with carcinogenesis and malignant behavior in bladder cancer (BC). We investigated the pathological significance and prognostic roles of urine and tissue levels of CP protein in BC patients.

Urine CP levels were measured using an enzyme-linked immunosorbent assay in 97 patients. CP expression in BC tissues was evaluated by immunohistochemical analysis in 176 patient samples.

Urine CP levels were positively associated with tumor grade and pT stage in non-muscle invasive BC (NMIBC). CP expression in BC tissues was positively associated with tumor growth and progression. Multivariate analysis demonstrated that high urine CP levels was an independent predictor of recurrence in the urinary tract in NMIBC (hazard ratio=2.87, p=0.016).

CP-related markers, especially urine CP levels, are useful biomarkers of malignant potential and prognosis in NMIBC.
