i-CR platform could be used to rapidly propagate primary colorectal tumor cells that represent individual patient tumors effectively by keeping the clonal heterogeneity and the genetic characteristics. Chemotherapy drug screenings with i-CR cells were comparable with that of PDX models. More importantly, i-CR results showed high accordance with the clinical outcomes of the enrolled CRC patients.

i-CR platform was capable to test and optimize therapeutic regimens pre-clinically, study cancer cell biology, and model tumor re-emergence to identify new targeted therapeutics from an effective personalized medicine standpoint.

The status of postoperative plasma mutation of microsatellite instability (MSI) CRC has not been systematically examined. In this study, we enrolled 30 MSI and 46 microsatellite stability (MSS) CRCs, and performed next generation sequencing on surgical tissues, postoperative plasma, and plasma during follow-up. Compared with MSS, MSI tumors had dissimilar genomic profiles, higher tumor mutation burden (TMB), and more frameshift mutations. In the postoperative plasma, more MSI CRCs were detected with tumor-derived mutations (77% in MSI vs 33% in MSS, p less then 0.001). The numbers of postoperative mutations were proportional to MSI tissues (Spearman r = 0.47, p = 0.023), while not for MSS. More proportion of postoperative plasma samples of MSI CRCs harbored frameshift mutations than MSS (p = 0.007). For the follow-up plasma, 93% (14 out of 15) MSI CRCs harbored tumor-derived mutations; 33% (4/12) MSS were mutation-positive, lower than MSI (p = 0.003). Thus, considering that MSI CRC had extremely distinct mutational characteristics in tumor and postoperative plasma compared with MSS CRC, we propose that the prognostic value of molecular residue identification in postoperative plasma needs to be independently evaluated in MSI and MSS CRCs.Various CMV anti-viral (AV) preventive strategies have been utilized in KTRs. We examined efficacy, safety and costs of CMV-AV prevention strategies in KTRs using a systematic literature review (SLR) of randomized controlled trials (RCTs) publications indexed in MEDLINE and Embase (from inception to November 2018). Thirty RCTs met inclusion criteria with 22 unique AV preventive strategies. selleck compound Prophylaxis was associated with significantly lower rates of CMV infection/disease (CMVi/d) compared to no prophylaxis (pooled odds ratio, pOR with 95% confidence interval (CI) CMVi 0.33; 0.19, 0.57; CMVd 0.27; 0.19; 0.39). Preemptive therapy (PET) had lower rates of CMVd (0.29; 0.11, 0.77), and medical costs compared to no PET. Prophylaxis had significantly lower rates of early CMVi/d, and higher rates of late CMVi and hematological adverse events (leukopenia, 2.93; 1.22, 7.04), and similar overall medical costs compared to PET. Studies involving head-to-head comparison of different prophylaxis approaches showed mixed findings with respect to optimum dose, duration and route of administration on CMV outcomes. Although there was heterogeneity across populations and interventions, both prophylaxis and PET strategies reduced CMVi/d compared to no prophylaxis/PET and had differential safety profile in terms of hematological adverse events. For comprehensiveness we did not limit study inclusion based on date; the wide time-period may have contributed to the heterogeneity in prevention approaches which subsequently made pooling studies a challenge. Despite demonstrated efficacy of prophylaxis/PET, our findings highlight the potential need of a novel intervention with a better safety profile and perhaps improved outcomes.The exercise pressor reflex is exaggerated in type 2 diabetes mellitus (T2DM). Hyperglycemia, a main characteristic of T2DM, likely contributes to this exaggerated response. However, the isolated effect of acute hyperglycemia, independent of T2DM, on the exercise pressor reflex is not known. Therefore, the purpose of this study was to determine the effect of acute, local exposure to hyperglycemia on the exercise pressor reflex and its two components, namely the mechanoreflex and the metaboreflex, in healthy rats. To accomplish this, we determined the effect of an acute locol intra-arterial glucose infusion (0.25 g/mL) on cardiovascular responses to static contraction (i.e., exercise pressor reflex) and tendon stretch (i.e., mechanoreflex) for 30 s, as well as hindlimb intra-arterial lactic acid (24 mM) injection (i.e., metaboreflex) in fasted unanesthetized, decerebrated Sprague-Dawley rats. We measured and compared changes in mean arterial pressure (MAP) and heart rate (HR) before and after glucose infusion. We found that acute glucose infusion did not affect the pressor response to static contraction (ΔMAP before 15 ± 2 mmHg, after 12 ± 2 mmHg; n = 8, p > 0.05), tendon stretch (ΔMAP before 12 ± 1 mmHg, after 12 ± 3 mmHg; n = 8, p > 0.05), or lactic acid injection (ΔMAP before 13 ± 2 mmHg, after 17 ± 3 mmHg; n = 9, p > 0.05). Likewise, cardioaccelerator responses were unaffected by glucose infusion, p > 0.05 for all. In conclusion, these findings suggest that acute, local exposure to hyperglycemia does not affect the exercise pressor reflex or either of its components.Oral squamous cell carcinoma (OSCC) is the major cause of morbidity and mortality in head and neck cancer patients worldwide. This malignant disease is challenging to treat because of the lack of effective curative strategies and the high incidence of recurrence. This study aimed to investigate the efficacy of a single and dual approach targeting ribosome biogenesis and protein translation to treat OSCC associated with the copy number variation (CNV) of ribosomal DNA (rDNA). Here, we found that primary OSCC tumors frequently exhibited a partial loss of 45S rDNA copy number and demonstrated a high susceptibility to CX5461 (a selective inhibitor of RNA polymerase I) and the coadministration of CX5461 and INK128 (a potent inhibitor of mTORC1/2). Combined treatment displayed the promising synergistic effects that induced cell apoptosis and reactive oxygen species (ROS) generation, and inhibited cell growth and proliferation. Moreover, INK128 compromised NHEJ-DNA repair pathway to reinforce the antitumor activity of CX5461.
