Human haematological and epithelial tumor-derived cell lines express distinct patterns of onco-microRNAs.

In this study, we analysed differences in miRNA expression profile between haematological and epithelial tumor-derived cell lines and explored their role in definying different cancer cells phenotypes. Cancer Focus microRNA PCR Panel was used to analyze eighty-four oncomiRNAs in two human haematological (K562 and HL-60) and in two epithelial (H460 and MCF-7) cancer cell lines. Bioinformatic tools were used to identify miRNA-specific signatures and to discover potentially deregulated pathways. Our analysis led to the identification of i) a large repertoire of miRNAs commonly expressed in the four cell lines, including two equally highly expressed (UPmiRs) and four equally low expressed (DNmiRs); ii) two miRNAs signatures, one associated with the haematological and one with the epithelial cell lines; iii) miRNA signatures specific for the acute or for the chronic myeloid leukemic cells; iv) miRNA signatures specific for the lung or for the breast carcinoma cells. As a whole, these results strengthen the significance of miRNAs profiling in human cancer subtyping, providing the ground for the identification of novel potential biomarkers for specific cancer cell phenotypes.

Authors: Kao S, Yadgar R, Enelow T, Friedman A Abstract Blastomycosis-like pyoderma (BLP) is a rare reactive skin disease that is most commonly caused by bacterial infection. Herein we present a case of BLP arising in lichen planus, a chronic inflammatory disease. We propose Wolf's isotopic response, or the appearance of a new skin disease at the site of an existing and unrelated disease, as the underlying molecular mechanism responsible for this unusual physical presentation. It is important that clinicians recognize atypical morphologies such as BLP, which mimics squamous cell carcinoma both clinically and pathol...

Abstract Leukemoid reaction (LR) is a reactive disease that exhibits abnormal blood values similar to leukemia, but not due to leukemia. One report showed that neonatal LR (NLR) was associated with elevated serum granulocyte colony stimulating factor (G-CSF) in only 30% of the study neonates. NLR is not always associated with the elevation of serum G-CSF. NLR was defined as a white blood cell count of ≥ 40 × 103/μL and/or blast cell concentration of> 2%. We have focused on NLR with fetal inflammatory response syndrome (FIRS), defined as a fetal systemic inflammatory reaction triggered by intrauterin...

Abstract Primary lung cancer is the most frequent cause of cancer-related deaths worldwide. Cisplatin has been used as a key drug in the treatment for patients with lung cancer; however, most of the patients failed to respond to cisplatin within several months, and the mechanisms underlying the cisplatin resistance have not been fully elucidated. Apoptosis-associated speck-like protein containing a caspase recruitment domain (ASC) is a key adaptor protein in the formation of inflammasomes. ASC is also involved in apoptotic signaling. Importantly, ASC expression is decreased in lung cancer and various cancers, but ...

Peripheral nervous system damage from hematologic malignancies is related to neoplastic cells infiltration of peripheral nerves or to monoclonal antibody production cross-reacting with peripheral nerves' antigens. Neurolymphomatosis (NL), a rare manifestation of hematologic malignancies, occurs when malignant cells invade the peripheral nerves leading to various manifestations. Here, we report a case of NL with 2 hematologic malignancies in a 79-year-old woman presenting with lower extremity pain/weakness. Investigation revealed anemia, IgM kappa monoclonal gammopathy, and elevated anti-MAG titer. Electrodiagnostic studies...

We report a 27-year-old woman with a history of adenoid cystic carcinoma of the submandibular gland presented with painful twitching of her left shoulder. Electrodiagnostic studies were consistent with a diagnosis of radiation-induced spinal accessory nerve hyperactivity. The patient failed conventional medical therapy. She was treated with an injection of botulinum toxin A, and within 1 month experienced significant relief of symptoms. We thus conclude that Botulinum toxin is a therapeutic option for the pain associated with radiation-induced peripheral nerve hyperactivity.

CONCLUSION Cognitive impairment can affect daily functioning, quality of life, and capacity to work in patients with cancer and those in remission. Consequently, cognitive assessment is now an important and necessary part of a comprehensive oncological care plan. Cancer-related cognitive impairment might be due to the direct effects of the cancer itself, nonspecific factors, or comorbid conditions that are independent of the disease and/or due to the adverse effects of the treatment or combination of treatments given for the disease. The prevalence and extent of cognitive impairment associated with cancer is recognized but...
