Cancer remains a highly lethal disease in the world. Currently, either conventional cancer therapies or modern immunotherapies are non-tumor-targeted therapeutic approaches that cannot accurately distinguish malignant cells from healthy ones, giving rise to multiple undesired side effects. Recent advances in nanotechnology, accompanied by our growing understanding of cancer biology and nano-bio interactions, have led to the development of a series of nanocarriers, which aim to improve the therapeutic efficacy while reducing off-target toxicity of the encapsulated anticancer agents through tumor tissue-, cell-, or organelle-specific targeting.

Our previous research demonstrated that compound licochalcone E can reduce glucose tolerance and lipid metabolism in diabetic rats, although its mechanism remains unknown. Here, we used palmitic acid (PA) to establish a PA-treated HepG2 model, and then examined glucose uptake, glucose consumption, and blood lipids to evaluate the effects of licochalcone E within the safe dose range in the model. Polymerase chain reaction (PCR) was used to detect the expression levels of key genes associated with liver gluconeogenesis; enzyme-linked immunosorbent assay (ELISA) was deployed to evaluate the concentration of inflammatory factors; and laser confocal microscopy and western blot were used to determine the levels of reactive oxygen species (ROS) and NLRP3 inflammasome signaling pathway-related proteins, respectively.

Transarterial embolization (TAE) is a palliative option commonly used for the treatment of advanced, unresectable hepatocellular carcinoma (HCC). However, patient prognosis in regards to overall survival has not improved with this method, mainly due to hypoxia‑inducible factor‑1α (HIF‑1α)‑induced angiogenesis and invasiveness. Thus, it is hypothesized that HIF‑1α may be an ideal knockout target for the treatment of HCC in combination with TAE.

Dysregulation of miR-124 has been reported to be involved in the pathophysiology of depression. Chaihu-Shugan-San, a traditional Chinese medicine, has antidepressive activity; however, the underlying mechanisms remain unclear. In this study, to generate a rodent model of depression, rats were subjected to a combination of solitary confinement and chronic unpredictable mild stress for 28 days.

Neurodegenerative diseases are among the most serious health problems affecting millions of people worldwide. Such diseases are characterized by a progressive degeneration and / or death of neurons in the central nervous system. Currently, there are no therapeutic approaches to cure or even halt the progression of neurodegenerative diseases.

Long noncoding RNAs (lncRNAs) regulate gene expression by acting with microRNAs (miRNAs). However, the roles of cancer specific lncRNA and its related competitive endogenous RNAs (ceRNA) network in hepatocellular cell carcinoma (HCC) are not fully understood. The lncRNA profiles in 372 HCC patients, including 372 tumor and 48 adjacent non-tumor liver tissues, from The Cancer Genome Atlas (TCGA) and NCBI GEO omnibus (GSE65485) were analyzed.

Context: The incidence of papillary thyroid cancer (PTC) shows a predominance in females, with a male:female ratio of 1:3, and none of the known risk factors are associated with gender difference. Increasing evidence indicates a role of estrogen in thyroid tumorigenesis, but the mechanism involved remains largely unknown.

Objective: This study aimed to assess the contribution of autophagy to estrogen receptor α (ERα)-mediated growth of PTC.

Aim: To investigate the mechanism by which galangin, a polyphenolic compound derived from medicinal herbs, induces apoptosis of hepatocellular carcinoma (HCC) cells.

Methods: The 3-(4,5-dimethyl-thiazol-2-yl)-2,5-diphenyl-tetrazolium bromide assay was used to measure cell viability. Apoptosis was evaluated by in situ uptake of propidium iodide and Hoechst 33258 and was then detected by fluorescence microscopy.

Germline mutations of the LKB1 tumor suppressor gene result in Peutz-Jeghers syndrome (PJS) characterized by intestinal hamartomas and increased incidence of epithelial cancers. Inactivating mutations in LKB1 have also been found in certain sporadic human cancers and with particularly high frequency in lung cancer. LKB1 has now been demonstrated to play a crucial role in pulmonary tumorigenesis, controlling initiation, differentiation, and metastasis.
