Chemoresistance is a key reason for treatment failure in colorectal cancer (CRC) patients. The tumor microenvironment of chemoresistant CRC is distinctly immunosuppressive, although the underlying mechanisms are unclear. The CRC data sets GSE69657 and GSE62080 were downloaded from the GEO database, and the correlation between TRPC5 and FAP expression was analyzed by Pearson method.

Article Synopsis
  • Anti-claudin (CLDN) 18.2 therapy is effective for advanced gastric cancer without HER-2, but this study focuses on its impact in HER-2-positive gastric cancer patients post-surgery.
  • Researchers evaluated the expression levels of CLDN 18.2 in 55 HER-2-positive patients, finding that higher levels were linked to poorer disease-free survival (DFS) and a worse prognosis, especially in those with lymph node involvement.
  • The study concludes that high CLDN 18.2 expression in HER-2-positive gastric cancer indicates a negative prognosis, suggesting a need for tailored treatment strategies following the development of anti-CLDN 18.2 therapies.

Article Synopsis
  • Recurrence is a major reason why treatment fails in patients with colorectal cancer (CRC), and while some factors like staging help predict recurrence, they don't always align with patient outcomes.
  • Circulating tumor cells (CTC) have been shown to have prognostic value, but past research has mainly focused on their quantity rather than their functional differences.
  • This study highlights the significance of CTC expressing the TRPC5 protein, finding that high levels of CTC-TRPC5 correlate with more advanced tumors and shorter disease-free survival, suggesting it could be a valuable tool for assessing CRC prognosis.

Background And Purpose: Chemoradiotherapy (CRT) has been widely applied in patients with advanced nasopharyngeal carcinoma (ANPC). However, limited imaging modality exists on the evaluation of early response to CRT. The purpose of this study was therefore to investigate whether 3D pseudo-continuous arterial spin labeling (3D pCASL) perfusion imaging could predict early response to CRT in ANPC patients.

Background: This study aimed to investigate the SRY-related higll-mobility-group box 10 (Sox10) expression in the pathological diagnosis of triple-negative breast cancer (TNBC). Furthermore, its correlation with the clinicopathological characteristics and disease-free survival rate in patients with TNBC was also evaluated to identify the diagnostic utility of Sox10 as a reliable biomarker for the diagnosis and prognosis of TNBC.

Methods: Using immunohistochemistry (IHC), we identified the expression of Sox10, GATA binding protein 3 (GATA-3), forkhead box protein A1 (FOXA1), gross cystic disease fluid protein (GCDFP15), and mammaglobin (MGB) in 376 cases of primary invasive breast cancer, and 77 cases of metastatic breast cancer.

Epithelial-mesenchymal transition (EMT) is considered as the key mechanism involved in cancer metastasis. Several studies showed that various cell membrane calcium channels play different roles in cancer metastasis. In the present study, the potential role of ATPase plasma membrane Ca transporting 4 (PMCA4) in regulating EMT in gastric cancer (GC) was investigated.

Article Synopsis
  • LINC02163 is found to be upregulated in breast cancer, similar to its role in gastric cancer, and is linked to tumor characteristics like size and metastasis, affecting patient survival rates.
  • Silencing LINC02163 leads to reduced cell proliferation, migration, and invasion, while promoting apoptosis in breast cancer cells, indicating its crucial role in cancer advancement.
  • The study reveals that LINC02163 operates through a mechanism involving microRNA-511-3p and HMGA2, suggesting its potential as a target for breast cancer diagnosis and treatment.

Background: We aimed to develop a clinical applicable nomogram to predict overall survival (OS) for patients with curatively resected nonmetastatic colorectal cancer.

Methods: Records from a retrospective cohort of 846 patients with complete information were used to construct the nomogram. The nomogram was validated in a prospective cohort of 379 patients.

Colorectal cancer (CRC) is the third most common malignancies in adults. Similar to other solid tumors, CRC cells show increased proliferation and suppressed apoptosis during the development and progression of the disease. Previous studies have shown that a novel tumor oncogene, spermatogenic basic helix-loop-helix transcription factor zip 1 (SPZ1), can promote proliferation.

Purpose: To evaluate the diagnostic efficacy in differentiating metastatic from inflammatory perigastric lymph nodes (LN) in patients with gastric cancer by using CT perfusion imaging (CTPI).

Method: A total of 115 annotated perigastric LN of 50 patients with gastric cancer confirmed by pathology underwent CTPI scan before operation. The scan data were postprocessed to acquire perfusion maps and parameters including blood flow (BF) and permeability surface (PS).

  • The study aimed to evaluate the effectiveness of CT perfusion imaging (CTPI) in detecting metastatic involvement of perigastric lymph nodes (PLN) in patients with T1 gastric cancer.
  • It analyzed 82 PLN from 33 patients, comparing the perfusion parameters like blood flow (BF) and permeability surface (PS) between metastatic and inflammatory lymph nodes, with significant results indicating differences in BF values.
  • The findings suggest that BF could be a reliable marker for identifying metastatic PLN, aiding clinical decisions for treatment in T1 gastric cancer cases.

Long noncoding RNAs (lncRNAs) have recently received more attention for their roles in tumor progression. LINC00261 was studied in this research to identify how it affects the progression of non-small cell lung cancer (NSCLC). Firstly, the expression of LINC00261 in NSCLC cells and paired samples of NSCLC tissue was detected by RT-qPCR.

Summary: Here we developed a tool called Breakpoint Identification (BreakID) to identity fusion events from targeted sequencing data. Taking discordant read pairs and split reads as supporting evidences, BreakID can identify gene fusion breakpoints at single nucleotide resolution. After validation with confirmed fusion events in cancer cell lines, we have proved that BreakID can achieve high sensitivity of 90.

Background: Elevated intracellular Ca ([Ca] ) level could lead to [Ca] overload and promote apoptosis via different pathways. In our previously study, up-regulated expression of transient receptor potential canonical channel (TRPC5) was proven to increase [Ca] level, and resulted in chemoresistance whereas not apoptosis in human colorectal cancer (CRC) cells. The ATP-dependent homeostatic maintenance of resting [Ca] should be important in this process.

Chemoresistance, the major obstacle in breast cancer chemotherapy, results in unnecessary chemotherapy and wasting of medical resources. No feasible method has been available to predict chemoresistance before chemotherapy. In our previous study, elevated expression of transient receptor potential channel TRPC5 was found to be an essential element for chemoresistance in breast cancer cells, and it was determined that it could be transferred to chemosensitive breast cancer cells through releasing extracellular vesicles (EV) containing TRPC5 from chemoresistant cells, resulting in acquired chemoresistance.
