Rebiopsy is considered an option for specific types of cancer, such as breast, non-small cell lung, and prostate cancer, in clinical trials and in practice. The benefit of rebiopsy comes from the selection of a new treatment strategy based on the genetic profile of the cells, which may reflect the development of drug resistance or hormonal changes. For colorectal cancer, the presence of different genomic mutations between the primary tumor and its metastases is rare, and rebiopsy is therefore not generally performed...

In our previous studies, a functionally unknown gene, family with sequence similarity 172, member A (FAM172A), was identified. High levels of FAM172A suppressed the cell cycle process, arresting HepG2 cells in G1/S and inhibiting cell proliferation. The present study aimed to confirm the expression levels of FAM172A and nucleotide-binding protein 1 (NUBP1) in colorectal cancer (CRC) tissues and normal colorectal tissues. The impact of FAM172A and NUBP1 on the prognosis of patients with CRC was also analyzed...

Among tumors of the major salivary glands, tumors in the sublingual gland are rare. Although mucoepidermoid carcinoma (MEC) represents a histological type of salivary gland tumor, it is occasionally difficult to diagnose due to its histological variation. The present study reports a case of MEC harboring a mastermind-like transcriptional coactivator 2 (MAML2) gene translocation in the sublingual gland. A 76-year-old Japanese woman with a mass in the left submandibular region was referred to Kurume University Hospital (Kurume, Japan)...

Recent studies suggest that allicin may play a role in chronic kidney disease (CKD), reducing hypertension and oxidative stress and improving renal dysfunction. In the present study, CKD was induced by 5/6 nephrectomy and the animals were divided into four treatment groups as follows: control (C), CKD, CKD+allicin (40 mg/kg pathway oral) (CKDA), and CKD+Losartan (20 mg/kg) (CKDL). After CKD induction, the rats developed hypertension from week 3 to the end of the study. This was associated with increased creatinine and blood urea nitrogen (BUN) levels in serum, increased albuminuria, increased urinary excretion of N-acetyl-β-d-glucosaminidase (NAG), increased nephrin expression, and incrased histological alterations in the cortex...

Leptospirosis is the most prevalent zoonosis affecting more than 1 million populations worldwide. Interestingly, leptospirosis endemic regions coincide with chronic kidney disease (CKD) hotspots largely due to flooding and agricultural overlaps. Acute leptospirosis induces multiple organ dysfunction including acute kidney injury and may predispose to CKD and end-stage renal disease, if not treated timely. Asymptomatic infection may carry the bacteria in the kidney and CKD progresses insidiously. Histologic finding of leptospirosis renal disease includes tubulointerstitial nephritis, interstitial fibrosis, and tubular atrophy...
