Abstract Despite therapeutic advances, the effective treatment for relapsed or refractory diffuse large B-cell lymphoma
(DLBCL) remains a major clinical challenge. Evasion of apoptosis through upregulating antiapoptotic B-cell
lymphoma-2 (BCL-2) family members and p53 inactivation, and abnormal activation of B-cell receptor signaling pathway are two important pathogenic factors for DLBCL. In this study, our aim is to explore a rational
combination of BCL-2 inhibitor plus Bruton’s tyrosine kinase (BTK) blockade or p53 activation for treating
DLBCL with the above characteristics. We demonstrated that a novel BCL-2 selective inhibitor APG-2575
effectively suppressed DLBCL with BCL-2 high expression via activating the mitochondrial apoptosis… More >

Abstract Anaplastic thyroid carcinoma (ATC) is resistant to standard therapies and has no effective treatment. Eukaryotic
translation initiation factor 5A2 (EIF5A2) has shown to be upregulated in many malignant tumors and proposed to be a critical gene involved in tumor metastasis. In this study, we aimed to investigate the expression
status of EIF5A2 in human ATC tissues and to study the role and mechanisms of EIF5A2 in ATC tumorigenesis
in vitro and in vivo. Expression of EIF5A2 protein was analyzed in paraffin-embedded human ATC tissues
and adjacent nontumorous tissues (ANCT) (n = 24) by immunochemistry. Expressions of EIF5A2 mRNA and
protein… More >

Abstract It has been reported that kindlin-3 expression is closely associated with progression of many cancers and
microRNA (miRNA) processing. However, the effects and precise mechanisms of kindlin-3 in acute myeloid
leukemia (AML) have not been well clarified. Our study aimed to explore the interaction between kindlin-3
and miR-4792 in AML. In our study, we found that the expression of kindlin-3 was dramatically increased in
AML samples and cell lines, and the miR-4792 level was significantly downregulated. Interestingly, the low
miR-4792 level was closely associated with upregulated kindlin-3 expression in AML samples. Moreover,
introduction of miR-4792 dramatically suppressed proliferation and invasion… More >

Abstract Chemotherapy is critical for the treatment of hepatocellular carcinoma (HCC). Despite the proapoptotic effects
of corosolic acid (CA) treatment, its underlying mechanism is not completely clear. The aim of this study
was to determine the molecular mechanism of CA in HCC treatment. MTT assay was used to determine the
IC50 of CA. Immunoprecipitation and immunofluorescence were used to detect the interaction and subcellular localization of Yes-associated protein (YAP) and mouse double minute 2 (MDM2). In addition, in vivo
xenotransplantation was performed to assess the effects of CA, YAP, and MDM2 on tumorigenesis. The IC50
of CA was about 40 µM… More >

Abstract The deubiquitinase cylindromatosis (CYLD) functions as a tumor suppressor inhibiting cell proliferation in
many cancer types including melanoma. Here we present evidence that a proportion of melanoma cells are
nonetheless addicted to CYLD for survival. The expression levels of CYLD varied widely in melanoma cell
lines and melanomas in vivo, with a subset of melanoma cell lines and melanomas displaying even higher
levels of CYLD than melanocyte lines and nevi, respectively. Strikingly, although short hairpin RNA (shRNA)
knockdown of CYLD promoted, as anticipated, cell proliferation in some melanoma cell lines, it reduced
cell viability in a fraction of melanoma cell… More >

Abstract miRNAs play an important role in progression of hepatocellular carcinoma (HCC). In this work, we assessed the
function of miR-202 in human HCC and identified BCL2 as its target. We found miR-202 expression was found significantly downregulated, while BCL2 expression was markedly upregulated in HCC tissues and cell lines (HepG2,
Hep3B, and HCCLM3). Both miR-202 and BCL2 were closely correlated with major vascular invasion and advanced
TNM stage as well as overall survival of HCC patients. Overexpression of miR-202 significantly inhibited cell proliferation, induced apoptosis and cell cycle arrest at the G0/G1 phase, and prevented tumor formation in a xenograft… More >

Abstract Osteosarcoma (OS), the most common bone cancer, causes high morbidity in children and young adults.
TRIM46 is a member of the family of tripartite motif (TRIM)-containing proteins that serve as important regulators of tumorigenesis. Here we investigate the possible role of TRIM46 in OS and the underlying molecular
mechanism. We report an increase in the expression of TRIM46 in OS and its association with tumor size,
Enneking’s stage, and patient prognosis. TRIM46 knockdown inhibits OS cell viability and cell cycle progression and induces apoptosis, while TRIM46 overexpression exerts inverse effects, which are inhibited by peroxisome proliferator-activated receptor alpha (PPAR )… More >

Abstract Although oxaliplatin serves as one of the first-line drugs prescribed for treating colorectal cancer (CRC), the
therapeutic effect is disappointing due to drug resistance. So far, the molecular mechanisms mediating oxaliplatin resistance remain unclear. In this study, we found the chemoresistance in oxaliplatin-resistant HCT116 cells
(HCT116/OXA) was mediated by the upregulation of ERCC1 expression. In addition, the acquisition of resistance induced epithelial–mesenchymal transition (EMT) as well as the Slug overexpression. On the contrary,
Slug silencing reversed the EMT phenotype, decreased ERCC1 expression, and ameliorated drug resistance.
Further mechanistical studies revealed the enhanced Slug expression resulted from the activation of AKT/… More >

Abstract Natural products are becoming increasingly popular in a variety of traditional, complementary, and alternative systems due to their potency and slight side effects. Natural compounds have been shown to be effective
against many human diseases, especially cancers. Sulforaphane (SFE) is a traditional Chinese herbal medicine.
In recent years, an increasing number of studies have been conducted to evaluate the antitumor effect of SFE.
The roles of SFE in cancers are mainly through the regulation of potential biomarkers to activate or inhibit
related signaling pathways. SFE has exhibited promising inhibitory effects on breast cancer, lung cancer, liver
cancer, and other malignant… More >

Abstract It has been demonstrated that microRNAs (miRNAs) act as oncogenes or tumor suppressors in a variety of
cancers. Our previous work suggested that miR-10a/b functioned as a tumor suppressor in gastric cancer,
and miR-10b was also reported to be significantly downregulated in advanced stage cervical cancer tissues.
However, the aberrant expression of miR-10b in cervical cancer and its possible role in cervical carcinogenesis
was largely unknown. In this study, we investigated the expression of miR-10b in cervical cancer tissues, carcinoma in situ tissues, mild dysplasia, moderate dysplasia, severe dysplasia tissues, and normal controls. We
found that miR-10b was significantly downregulated… More >
