Synergistic antitumor activity by dual blockade of CCR1 and CXCR2 expressed on myeloid cells within the tumor microenvironment.

Background: Chemokine signaling within the tumor microenvironment can promote tumor progression. Although CCR1 and CXCR2 on myeloid cells could be involved in tumor progression, it remains elusive what effect would be observed if both of those are blocked.

Methods: We employed two syngeneic colorectal cancer mouse models: a transplanted tumor model and a liver metastasis model.

A case of testicular cancer in a long-term hydranencephaly survivor with undescended testes.

Introduction: The development of malignant tumors in patients with hydranencephaly is extremely rare. We describe the first case of testicular cancer that developed in the undescended testes of a long-term survivor of hydranencephaly.

Case Presentation: A 32-year-old man with severe cerebral palsy due to hydranencephaly was referred to our department for the evaluation of a subcutaneous lump in the lower right abdomen.

Downregulation of osteoprotegerin in colorectal cancer cells promotes liver metastasis via activating tumor-associated macrophage.

Osteoprotegerin (OPG) is a secreted cytokine that functions as a decoy receptor for receptor activator of nuclear factor kappa-B (RANK) ligand (RANKL). Anti-RANKL treatment for bone metastasis has been widely accepted for solid tumors. However, the mechanism of OPG-RANKL-RANK signaling in systemic colorectal cancer (CRC) metastasis remains unclear.

Female intravesical foreign body penetrating the bladder wall: A rare case of traditional Asian hair stick .

A female in her thirties inserted an Asian traditional hair stick, , into her urinary bladder for sexual gratification. We need to know that everyday objects can become bladder foreign bodies and how to manage them properly.

Neutrophil Extracellular Traps Promote Metastases of Colorectal Cancers through Activation of ERK Signaling by Releasing Neutrophil Elastase.

Neutrophil extracellular traps (NETs) play important roles in host immunity, as there is increasing evidence of their contribution to the progression of several types of cancers even though their role in colorectal cancers (CRCs) remains unclear. To investigate the clinical relevance of NETs in CRCs, we examined the expression of citrullinated histone H3 using immunohistochemistry and preoperative serum myeloperoxidase-DNA complexes in CRC patients using an enzyme-linked immunosorbent assay. High expression of intratumoral or systemic NETs was found to correlate with poor relapse-free survival (RFS), for which it is an independent prognostic factor.

Generation of the Y-chromosome linked red fluorescent protein transgenic mouse model and sexing at the preimplantation stage.

In mammals, sexual fate is determined by the chromosomes of the male and female gametes during fertilization. Males (XY) or females (XX) are produced when a sperm containing a Y or X-chromosome respectively fertilizes an X-chromosome-containing unfertilized egg. However, sexing of preimplantation stage embryos cannot be conducted visually.

Dual blockade of macropinocytosis and asparagine bioavailability shows synergistic anti-tumor effects on KRAS-mutant colorectal cancer.

Mutations of KRAS gene are found in various types of cancer, including colorectal cancer (CRC). Despite intense efforts, no pharmacological approaches are expected to be effective against KRAS-mutant cancers. Macropinocytosis is an evolutionarily conserved actin-dependent endocytic process that internalizes extracellular fluids into large vesicles called macropinosomes.

Effect of herbal medicine daikenchuto on gastrointestinal symptoms following laparoscopic colectomy in patients with colon cancer: A prospective randomized study.

We conducted a prospective randomized study to investigate the effect of daikenchuto (DKT) on abdominal symptoms following laparoscopic colectomy in patients with left-sided colon cancer. Patients who suffered from abdominal pain or distention on postoperative day 1 were randomized to either the DKT group or non-DKT group. The primary endpoints were the evaluation of abdominal pain, abdominal distention, and quality of life.

A novel tissue specific alternative splicing variant mitigates phenotypes in Ets2 frame-shift mutant models.

E26 avian leukemia oncogene 2, 3' domain (Ets2) has been implicated in various biological processes. An Ets2 mutant model (Ets2), which lacks the DNA-binding domain, was previously reported to exhibit embryonic lethality caused by a trophoblast abnormality. This phenotype could be rescued by tetraploid complementation, resulting in pups with wavy hair and curly whiskers.

A patient with superior mesenteric artery lymph node metastasis after laparoscopic gastrectomy for gastric cancer with Adachi type VI vascular anomaly: A case report.

Introduction: Due to recent advances in surgical procedures and instruments, laparoscopic gastrectomy for gastric cancer has been widely performed, and previous studies reported laparoscopic surgery for gastric cancer with Adachi type VI vascular anomaly. In Adachi type VI patients, the common hepatic artery (CHA) originates from the superior mesenteric artery (SMA); therefore, the route of lymph flow differs from the normal route, and the supra- and infrapyloric lymph nodes (LN) may reach SMA LN. However, metastasis has not yet been reported.
