Aims: To assess the prognostic significance of apoptosis related markers in bladder cancer.
Methods: A tissue microarray containing 179 bladder carcinomas from cystectomy specimens was analysed immunohistochemically for active caspase-3, single-stranded DNA (ssDNA), p53, Bcl-2, Bax, and COX-2, in correlation to clinicopathological factors.
Results: Active caspase-3, ssDNA, p53, Bax and COX-2 were more frequently observed among high grade and higher stage (> or =T2) carcinomas compared with low grade and lower stage (T1) tumours. On the contrary, Bcl-2 was more frequently detected in T1 than in > or =T2 carcinomas. Active caspase-3 correlated with a better survival of the patients.
Conclusions: The decreased detection of active caspase-3 and ssDNA and the increased presence of Bcl-2 in T1 carcinomas suggest that alterations in interrelated apoptosis markers may play an important role in the progression of urothelial carcinoma from a superficially infiltrating to a muscle invading tumour and would help to better characterise a subpopulation of T1 carcinomas that could profit from early cystectomy or more aggressive adjuvant chemotherapy. Active caspase-3 might be an important prognostic factor in bladder cancer.

Alcoholic liver disease (ALD) is a commonly known liver disease mediated by prolonged alcohol consumption. Aescin is a triterpene saponin that can manage several conditions, including brain trauma, arthritis, venous congestion, stroke, and thrombophlebitis. Even so, studies illustrating the aescin role in ALD are scarce.

Background: Intestinal larva invasion is a crucial step of Trichinella spiralis infection. Intestinal infective larvae (IIL) and their excretory/secretory proteins (ESP) interact with gut epithelium, which often results in gut epithelium barrier injuries. Previous studies showed when T.

Pyroptosis, an excellent form of immunogenic cell death that can effectively activate antitumor immune responses, is attracting considerable interest as a promising approach for cancer immunotherapy. Immunogenic pyroptosis can recruit and stimulate dendritic cells to provoke further activation and tumor infiltration of T cells by releasing danger-associated molecular patterns, thus improving the tumor response to PD-1/PD-L1 checkpoint blockade immunotherapy. Here, we report the discovery of a bifunctional photosensitizer Nile Violet that can simultaneously trigger caspase-3/GSDME-mediated immunogenic pyroptosis and PD-L1 downregulation for cancer photoimmunotherapy.

Acute kidney injury (AKI) is a common serious complication of sepsis that is characterized by the rapid deterioration of kidney function. Neng-Jing-Huo (NJH) is an essential oil blend, including Gaultheria procumbens, Zingiber officinale, Bulnesia sarmientoi, Artemisia vulgaris, and Styrax benzoin oils, with antimicrobial, antioxidant, and anti-inflammatory activities. Here, we investigated the effects of NJH on oxidative stress, inflammatory response, and apoptosis in an in vitro septic AKI model and explored the underlying mechanisms.
