Up-regulation of PIK3R3 (Phosphoinositide-3-Kinase Regulatory Subunit 3), the regulatory subunit of PI3K is correlated with the drug resistance of the glioblastoma cells. In the present study, the effect of PIK3R3 siRNA on erlotinib sensitivity of the U373-MG glioblastoma cells was explored.
After PIK3R3 siRNA transfection, the expression of PIK3R3 mRNA was measured using RT-qPCR. Trypan blue exclusion assay was used to explore the effect of PIK3R3 siRNA on cell proliferation. The effects of PIK3R3 siRNA and erlotinib, alone and in combination, on cell survival and apoptosis were measured using MTT assay and ELISA cell death assay, respectively.
Our data showed that PIK3R3 siRNA markedly suppressed the expression of PIK3R3 in a time dependent way, inhibited the proliferation of the U373-MG cells and triggered apoptosis (p <0.05, relative to blank control). Pretreatment with PIK3R3 siRNA synergistically decreased the cell survival rate and lowered the IC50 of erlotinib. Moreover, PIK3R3 siRNA markedly enhanced the apoptotic effect of erlotinib.
Our data propose that suppression of PIK3R3 can effectively triggers apoptosis and enhances the sensitivity of the glioblastoma cells to EGFR-TKI erlotinib. Thus, PIK3R3 can be a potential therapeutic target in glioblastoma patients.<br />.

Several studies have recently indicated a huge shifting pattern toward early age onset cases in breast cancer (BC) patients. However, the studies exerted relatively limited to the Caucasian population. This preliminary study is aimed to investigate the genetic risk factors for young BC patients specifically in Indonesia population.
DNA samples were extracted from 79 BC patients aged younger than 40 years old and 90 healthy samples. These DNA samples were sequenced using Illumina NextSeq 500 platform and preprocessed to extract the single-nucleotide polymorphisms (SNPs) data. Firstly, multiple univariate logistic regressions were performed to test the association between each SNP and BC incidence in young patients. Furthermore, to analyze the polygenic effects derived from multiple SNPs, we employed a multivariate logistics regression.
There were only 15 SNPs passed our 95% call rate threshold thus subsequently were used in the association test. One of these variants, rs3219493, emerged to be significantudy, our finding on significant association of intronic MUTHY with the early onset of BC in Indonesia led to a broadened insight of population-based unique aspect to being taken into an in-depth account for and advancement of chemotherapy.
Complementary and Alternative Medicine (CAM) is widely used among cancer patients worldwide. This prospective observational study aimed to show the effect of CAM use on chemotherapy delivery in Thai patients.
During March 2014 to February 2015, the patients with breast, lung or colorectal cancer receiving first cycle chemotherapy at King Chulalongkorn Memorial Hospital were enrolled. The correlation between CAM using and chemotherapy schedule delay and dose reduction, dose intensity, quality of life and adverse event rates were analyzed.
There were 80 (44.20%) patients using CAM among 181 enrolled patients. Seventy six CAM users and 97 non-CAM users receiving 2nd cycle of chemotherapy were included for primary analysis. The chemotherapy schedules were delayed and/or reduced in 40 (52.6%) and 48 (49.5%) in CAM users and non-CAM users, respectively, p =0.681. The mean relative dose intensity (RDI) were 92.4% and 94.1% in CAM and non-CAM users, respectively, p=0.244. However, there were significantly more CAM users receiving chemotherapy less than 90% RDI (34.8% vs 19.8%, p=0.033). As compared to first cycle, at third cycle, the mean QOL score changes were -4.63 (95% CI -2.49-9.27) and -8.02 (-2.36- 9.142) in CAM user and non-CAM user, respectively (p=0.255). There were significantly higher rates of grade 3 or 4 anemia (5.1% vs 0%, p=0.024), and grade 2 malaise (19.0% vs 5.1%, p=0.004) in CAM users.
There were similar overall rates of chemotherapy schedule delay and dose reduction between CAM- and non-CAM users. However, there were less CAM-users achieving 90% chemotherapy RDI.

Rectal cancer is a pervasive type of malignancy that accounts for one-third of colorectal cancers worldwide. Several studies have assessed the use of laparoscopic surgery as a treatment option. However, there is an ongoing debate regarding its oncological safety.
This retrospective study included 270 patients with non-metastatic rectal cancer who underwent either laparoscopic resection (LR, n = 93) or open resection (OR, n = 177) in an academic medical center. The primary outcomes were overall survival (OS) and disease-free survival (DFS), whereas the secondary outcome was postoperative complications. We performed propensity score analyses and compared outcomes. Univariate survival analyses using Kaplan-Meier plots and Cox proportional hazard regression models were also conducted.
In the propensity score matching analyses, 93 LR- and 93 OR-matched patients were compared. The overall median follow-up time was 3.95 years (range, 1.98‒5.55 years). MRTX1719 The 3-year OS was similar between the groups (LR 79.1% vs OR 79.2%, p = 0.82). Meanwhile, the DFS rate was also comparable between the groups (LR 77.8% vs OR 73.2%, p = 0.53). No significant differences in operative blood loss or hospital stay between the groups were observed (150 vs 150 mL, p = 0.74; 9 vs 10 days, p = 0.077, respectively). Also, no difference was found in postoperative complications between the groups (p = 0.23). However, LR was associated with a longer operative time than OR (455 vs 356 min, p < 0.001) and the number of lymph nodes harvested in LR was slightly fewer than OR (10 vs 11, p = 0.045).
LR of rectal cancer is safe, feasible, and comparable to standard OR in terms of the oncologic outcomes. However, LR required longer operative times. A well-designed prospective study with a large number of participants and long follow-up period is needed to show significant differences between the two groups.<br />.

BCR ABL oncogene encodes the BCR-ABL chimeric protein, which is a constitutively activated non-receptor tyrosine kinase. The BCR-ABL oncoprotein is a key molecular basis for the pathogenesis of chronic myeloid leukemia (CML) via activation of several downstream signaling pathways including JAK/STAT pathway. Development of leukemia involves constitutive activation of signaling molecules including, JAK2, STAT3, STAT5A and STAT5B. Thymoquinone (TQ) is a bioactive constituent of Nigella sativa that has shown anticancer properties in various cancers. The present study aimed to evaluate the effect of TQ on the expression of BCR ABL, JAK2, STAT3, STAT5A and STAT5B genes and their consequences on the cell proliferation and apoptosis in K562 CML cells.
BCR-ABL positive K562 CML cells were treated with TQ. Cytotoxicity was determined by Trypan blue exclusion assay. Apoptosis assay was performed by annexin V-FITC/PI staining assay and analyzed by flow cytometry. Transcription levels of BCR ABL, JAK2, STAT3, STAT5A and STAT5B genes were evaluated by reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Protein levels of JAK2 and STAT5 were determined by Jess Assay analysis.
TQ markedly decreased the cell proliferation and induced apoptosis in K562 cells (P < 0.001) in a concentration dependent manner. TQ caused a significant decrease in the transcriptional levels of BCR ABL, JAK2, STAT3, STAT5A and STAT5B genes (P < 0.001). TQ induced a significant decrease in JAK2 and STAT5 protein levels (P < 0.001).
our results indicated that TQ inhibited cell growth of K562 cells via downregulation of BCR ABL/ JAK2/STAT3 and STAT5 signaling and reducing JAK2 and STAT5 protein levels.

Paeoniflorin (PF), a compound found in Paeonia lactiflora and Paeonia suffruticosa, has anticancer potential, particularly in inhibiting migration and invasion, the resistant cancer cells hallmarks. To date, the mechanism of overcoming tamoxifen resistance in breast cancer is not yet elucidated. This research aims to explore the potential target of PF as a co-treatment for circumventing breast cancer resistance to tamoxifen with a genomic understanding-bioinformatics.
Microarray data originating from GSE67916 and GSE85871 in the NCBI GEO database was analyzed to obtain differentially expressed genes (DEGs). Further analyses were performed on DEGs using the DAVID v6.8, STRING-DB v11.0, the Cytoscape, and cBioportal. Gene expression analysis validation in breast cancer cells and tamoxifen-resistant breast cancer cells was accomplished using GEPIA and ONCOMINE databases. Survival rate analysis of selected genes was conducted using Kaplan-Meier.
We obtained 175 DEGs from the two samples (tamoxifen-resistanton is needed.
To determine the therapeutic efficacy of Kali haldi in the management of Oral submucous Fibrosis (OSMF) v/s steroid therapy.
A clinical prospective study was conducted on 42 patients of oral submucous fibrosis were equally divided into 2 groups. Group A patients were treated with a mixture of powdered Kali Haldi and aloe vera gel in equal ratio 3 times a day for 3 months. Group B patients were treated with intralesional injection of hydrocortisone and hyaluronidase for 6 weeks with oral antioxidant supplements for 3 months. Burning sensation, cheek flexibility, mouth opening, and tongue protrusion were evaluated before, during, and after treatment at an interval of 15 days, 1 month, 2, month and 3 months.
Statistically significant results were obtained at the end of 3 months duration for both the groups (P < 0.001). The Symptomatic correction was more evident in the case of Group A patients than Group B. Response of the ayurvedic regimen was potentially better as compared to the regular steroid therapy.
The study concludes that Combination therapy works wonders in the case of OSMF in stages I, II, III and can be a good option, comparatively safe and with negligible side effects, but potent and equally effective management of oral submucous fibrosis. Henceforth, it will be better to do such kinds of studies on a vast scale including larger samples and longer duration to check the efficacy and durability of this ancient ayurvedic regimen.
