APOA5 alleviates reactive oxygen species to promote oxaliplatin resistance in PIK3CA-mutated colorectal cancer.

Although platinum-based chemotherapy is the frontline regimen for colorectal cancer (CRC), drug resistance remains a major challenge affecting its therapeutic efficiency. However, there is limited research on the correlation between chemotherapy resistance and lipid metabolism, including PIK3CA mutant tumors. In this present study, we found that PIK3CA-E545K mutation attenuated cell apoptosis and increased the cell viability of CRC with L-OHP treatment and .

Glycolytic enzyme HK2 promotes PD-L1 expression and breast cancer cell immune evasion.

Immune therapies targeting the PD-1/PD-L1 pathway have been employed in the treatment of breast cancer, which requires aerobic glycolysis to sustain breast cancer cells growth. However, whether PD-L1 expression is regulated by glycolysis in breast cancer cells remains to be further elucidated. Here, we demonstrate that glycolytic enzyme hexokinase 2 (HK2) plays a crucial role in upregulating PD-L1 expression.

Shape Designed Implanted Drug Delivery System for Hepatocellular Carcinoma Therapy.

In this study, an intelligent drug delivery system (DDS) based on implanted triboelectric nanogenerator (iTENG) and red blood cell (RBC) is established for hepatocellular carcinoma (HCC) therapy. Apatinib (APA), as an oral antitumor drug, which can inhibit the expression of vascular endothelial growth factor receptor-2 (VEGFR2) is loaded inside RBC, realizing the transform from oral formulation to injection preparation. Multishape designed iTENG adapted for different implant sites and environments can harvest biomechanical energy efficiently.

Elevated LOXL2 expression by LINC01347/miR-328-5p axis contributes to 5-FU chemotherapy resistance of colorectal cancer.

Chemotherapy resistance after curative surgery is a major contributor to the mortality of colorectal cancer (CRC). Detailed mechanism studies of specific molecular alterations are critical to improving the available therapies for long-term disease administration. We explored the functional role of LINC01347 in chemotherapy resistance of CRC.

AB4 inhibits Notch signaling and promotes cancer cell apoptosis in liver cancer.

The etiology for liver cancer has been clearly defined. Unfortunately, therapeutic approaches for liver cancer are rather limited, and liver cancer is insensitive to chemotherapy and radiotherapy. Traditional Chinese medicine (TCM) has become a promising strategy for cancer treatment as TCM elicits broad spectrum anticancer activity.

LncRNA POU3F3 Contributes to Dacarbazine Resistance of Human Melanoma Through the MiR-650/MGMT Axis.

Alkylating agents are critical therapeutic options for melanoma, while dacarbazine (DTIC)-based chemotherapy showed poor sensitivity in clinical trials. Long non-coding RNAs (lncRNAs) were highlighted in the progression of malignant tumors in recent years, whereas little was known about their involvement in melanoma. The functional role and molecular mechanism of lncRNA POU3F3 were evaluated on DTIC-resistant melanoma cells.

Anemoside B4 exerts anti-cancer effect by inducing apoptosis and autophagy through inhibiton of PI3K/Akt/mTOR pathway in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality worldwide and novel therapeutic approaches are urgently required. Anemoside B4 (AB4) is a compound extracted from (). Previous studies have indicated that extract saponins has anti-cancer activity.

Overexpression of Nmnat improves the adaption of health span in aging Drosophila.

Nmnat is a stress response protein which has been involved in a variety of biological processes. However, the effects of Nmnat on aging have not yet been investigated. The present study revealed the effects of Nmnat on aging of Drosophila and uncovered its underlying mechanism.

"Less Blue, More Clean": CuO nano-cubic functionalized hydrogel for the energy transformation of light-emitting screens.

Cubic CuO nanoparticle modified hydrogel (CMHG) was synthesized to address two major problems (harmful irradiation and high density pathogens) of the current light-emitting screens simultaneously. The as-prepared hydrogel could conveniently form an adjustable semitransparent film over various shaped screens to provide enhanced antibacterial activity and longer CuO service life. More importantly, with the aid of cubic CuO nanoparticles, the energy of the harmful blue light irradiation could be effectively transformed into a photocatalysed power source to sterilize the surface of the screen.

[Application of lateral malleolus hook-plate in treatment of stage II supination-adduction type medial malleolus fracture].

Objective: To investigate the application of lateral malleolus hook-plate for the treatment of stage II supination-adduction type medial malleolus fractures.

Methods: Between January 2011 and June 2013, 21 patients with stage II supination-adduction type ankle fractures were treated with lateral malleolus hook-plate, including 12 males and 9 females with an average age of 55.5 years (range, 27-65 years).
