Abstract Hepatocellular carcinoma (HCC) is the most prevalent subtype of primary liver cancer and one of the leading causes of cancer-related death in the world. Liver cancer stem cells (CSCs) have been well established to be responsible for liver tumorigenesis, metastasis, drug resistance and tumor relapse. Yet the underlying mechanisms of CSCs self-renewal and maintenance are poorly understood. Here, we first report that SH3GL1 was dramatically upregulated in liver cancer and higher SH3GL1 expression was significantly correlates with worse clinical outcomes of liver cancer patients. Loss of function experiments demonstrate that SH3GL1 functions as a novel oncogene to potentiate liver cancer cell proliferation and liver CSCs self-renewal maintenance in vitro as well as xenograft tumor grow in vivo. Mechanistically, our study reveals that SH3GL1 facilitates liver CSCs by physically interacting with and activating β-catenin signaling. Our study characterizes SH3GL1 as a new regulator of oncogenic β-catenin signaling and defines newly therapeutic target for liver cancer patients.

Liver cancer is the fifth most common cancer in Indonesia. This research is to find out the prevalence and characteristics of liver cancer patients in Immanuel Hospital Bandung within the January 2013 until December 2014 period based on age, gender, clinical symptoms and predilections. This study was a descriptive verificative research with data retrieval of patients medical records that have been diagnosed with liver cancer that were hospitalized in Immanuel Hospital Bandung within January 2013 until December 2014 period. The study showed that the liver cancer patient prevalence in Immanuel Hospital Bandung within the period of January 2013 until December 2014 was 46 people. Characteristics of liver cancer patients in Immanuel Hospital Bandung within January 2013 until December 2014 period showed that the most liver cancer patients were male, compare with female with ratio 4:1, the most common age group of 56-65 years old, the most common clinical symptoms were abdominal pain with or without reffered pain to the right scapular bone and the most common predilection was right lobe of the liver. Key words: liver cancer, patients' characteristics, prevalence

Aim: To design D-Mannose conjugated 5-Fluorouracil (5-FU) loaded Jackfruit seed starch nanoparticles (JFSSNPs) for site specific delivery. Background: Liver cancer is the third leading cause of death in world and fifth most often diagnosed cancer is the major global threat to public health. Treatment of liver cancer with conventional method bears several side effects, thus to undertake these side effects as a formulation challenge, it is necessary to develop novel target specific drug delivery system for the effective and better localization of drug into the proximity of target with restricting the movement of drug in normal tissues. Objective: To optimize and characterize the developed D-Mannose conjugated 5-Fluorouracil (5-FU) loaded Jackfruit seed starch nanoparticles (JFSSNPs) for effective treatment of liver cancer. Materials and methods: 5-FU loaded JFSSNPs were prepared and optimized formulation had higher encapsulation efficiency were conjugated with D-Mannose. These formulations were characterized for size, morphology, zeta potential, X-Ray Diffraction, and Differential Scanning Calorimetry. Potential of NPs were studied using in vitro cytotoxicity assay, in vivo kinetic studies and bio-distribution studies. Result and discussion: 5-Fluorouracil loaded NPs had particle size between 336 to 802nm with drug entrapment efficiency was between 64.2 to 82.3%. In XRD analysis, 5-FU peak was diminished in the diffractogram, which could be attributed to the successful incorporation of drug in amorphous form. DSC study suggests there was no physical interaction between 5- FU and Polymer. NPs showed sustained in vitro 5-FU release up to 2 hours. In vivo, mannose conjugated NPs prolonged the plasma level of 5-FU and assist selective accumulation of 5-FU in the liver (vs other organs spleen, kidney, lungs and heart) compared to unconjugated one and plain drug. Conclusion: In vivo, bio-distribution and plasma profile studies resulted in significantly higher concentration of 5- Fluorouracil liver suggesting that these carriers are efficient, viable, and targeted carrier of 5-FU treatment of liver cancer.

Background: Ubiquitin specific protease 48 (USP48) is a member of the deubiquitinating enzymes (DUBs) family. However, the function of USP48 in ovarian cancer remains unclear. Objective: The present study reveals that USP48 knockdown could significantly inhibit cell migration and invasion in ES2, 3AO and A2780 cells, without affecting cell proliferation. Methods: After carboplatin (CBP) treatment, the USP48 ablation increases the apoptosis rate, and the cleaved PARP and cleaved caspase 3 expression levels in ES2, 3AO and A2780 cells. The subcutaneous tumor and intraperitoneally injected experiments demonstrated that the USP48 knockdown significantly increases responsiveness to CBP, and alleviates the metastasis in vivo. Meanwhile, USP48 deficiency results in the improved survival of mice. Results: Finally, the analysis of clinical samples and the TCGA and Kaplan-Meier Plot database revealed that the high expression of USP48 in ovarian cancer patients is associated with poor survival and resistance to CBP therapy. Conclusion: In summary, USP48 may be a potential therapeutic target for ovarian cancer patients.

BACKGROUND: Pyruvate kinase M2 (PKM2) was overexpressed in many cancers, and high PKM2 expression was related with poor prognosis and chemoresistance. OBJECTIVE: We investigated the expression of PKM2 in breast cancer and analyzed the relation of PKM2 expression with chemotherapy resistance to the neoadjuvant chemotherapy (NAC). We also investigated whether PKM2 could reverse chemoresistance in breast cancer cells in vitro and in vivo. METHODS: Immunohistochemistry (IHC) was performed in 130 surgical resected breast cancer tissues. 78 core needle biopsies were collected from breast cancer patients before neoadjuvant chemotherapy. The relation of PKM2 expression and multi-drug resistance to NAC was compared. The effect of PKM2 silencing or overexpression on Doxorubicin (DOX) sensitivity in the MCF-7 cells in vitro and in vivo was compared. RESULTS: PKM2 was intensively expressed in breast cancer tissues compared to adjacent normal tissues. In addition, high expression of PKM2 was associated with poor prognosis in breast cancer patients. The NAC patients with high PKM2 expression had short survival. PKM2 was an independent prognostic predictor for surgical resected breast cancer and NAC patients. High PKM2 expression was correlated with neoadjuvant treatment resistance. High PKM2 expression significantly distinguished chemoresistant patients from chemosensitive patients. In vitro and in vivo knockdown of PKM2 expression decreases the resistance to DOX in breast cancer cells in vitro and tumors in vivo. CONCLUSION: PKM2 expression was associated with chemoresistance of breast cancers, and could be used to predict the chemosensitivity. Furthermore, targeting PKM2 could reverse chemoresistance, which provides an effective treatment methods for patients with breast cancer.
