Cellular retinol binding protein 1 transfection reduces proliferation and AKT-related gene expression in H460 non-small lung cancer cells. Mol Biol Rep 2020; 47:6879-6886. [PMID: 32909215 PMCID: PMC7561531 DOI: 10.1007/s11033-020-05744-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Revised: 08/13/2020] [Accepted: 08/28/2020] [Indexed: 12/31/2022]
Abstract
In recent years, new treatments with novel action mechanisms have been explored for advanced non-small cell lung cancer (NSCLC). Retinoids promote cancer cell differentiation and death and their trafficking and action is mediated from specific cytoplasmic and nuclear receptors, respectively. The purpose of this study was to investigate the effect of Cellular retinol binding protein-1 (CRBP-1) transfection in H460 human NSCLC cell line, normally not expressing CRBP-1. H460 cells were transfected by using a vector pTargeT Mammalian expression system carrying the whole sequence of CRBP-1 gene. For proliferation and apoptosis studies, cells were treated with different concentrations of all-trans Retinoic Acid (atRA) and retinol. AKT-related gene expression was analyzed by using western blot and Signosis array and results analysed by one-way analysis of variance (ANOVA) or by t-student test. CRBP-1+ showed reduced proliferation and viability in basal condition and after atRA treatment when compared to empty-transfected H460 cells. Reduced proliferation in CRBP-1+ H460 cells associated to the down-regulation of pAKT/pERK/pEGFR-related genes. In particular, gene array documented the down-regulation of AKT and Stat-3-related genes, including M-Tor, Akt1, Akt2, Akt3, Foxo1, p27, Jun. Restoration of CRBP-1 expression in H460 cells reduced proliferation and viability in both basal condition and after atRA treatment, likely by down-regulating AKT-related gene level. Further studies are needed to better clarify how those CRBP-1-related intracellular pathways contribute to counteract NSCLC progression in order to suggest a potential tool to improve efficacy of retinoid anti lung cancer adjuvant therapy.

Skin lesions after prophylactic mastectomy and immediate reconstruction. PLASTIC AND RECONSTRUCTIVE SURGERY-GLOBAL OPEN 2014; 1:e82. [PMID: 25289276 PMCID: PMC4174102 DOI: 10.1097/gox.0000000000000009] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2013] [Accepted: 09/10/2013] [Indexed: 11/27/2022]
Abstract
SUMMARY Metastatic breast carcinoma can mimic benign cutaneous lesions. Breast surgeons should be aware of skin manifestations to be able to distinguish them and set a proper therapeutic strategy. A clinical case of cutaneous lesion after breast cancer is presented. A 41-year-old woman with a history of left breast cancer underwent a prophylactic right nipple-sparing mastectomy with immediate breast implant reconstruction. After surgery, she attended our service due to a right periareolar rash resistant to medical treatment, accompanied by cutaneous induration and fixed axillary adenopathy. A differential diagnosis of skin metastases was considered. Cutaneous metastases should be the first diagnosis of skin lesions in oncological patients due to the implications in terms of treatment and prognosis. However, differential diagnoses have to be discussed.

Cutaneous metastases of visceral tumours: a review. J Cancer Res Clin Oncol 2008; 135:1-14.

Abstract
BACKGROUND Up to 10% of all visceral malignancies develop cutaneous metastases. As cutaneous metastases are underestimated and underdiagnosed they can be a clinical challenge. The clinical appearance and patterns of distribution of cutaneous metastases, the characterisation of clinical outcomes and available therapeutic options are compiled. PATIENTS AND METHODS Literature (over the last 6 years) MESH in terms of cutaneous metastases was comprehensively evaluated. Characteristics from 92 available cases are elaborated and adjusted with terms (time unlimited) of published epidemiological reviews to single organs. RESULTS The broad clinical spectrum with differential diagnoses is displayed. An allocation of cutaneous metastases and a particular organ is not reliable. In 22% of all cases cutaneous metastases can lead to the diagnosis of an internal malignoma. The majority of cases reveal cutaneous metastases to emerge in a tumour-free interval in about 36 months, after a successful treatment of the primary tumour, most commonly along with other organ metastases. Probable survival turned out to be less than 12 months. Consistently with this end-stage condition, treatment aligns with rules of palliation. Local treatment of choice is excision. Only a minority of investigators attempted to come up with tumour-specific treatment strategies, and almost no randomised therapy studies can be presented. CONCLUSION A reference guide of cutaneous metastases is given; the clinical spectrum is adjusted to an actual status; state of the art of the treatment is accomplished. An epidemiological, improved registration and diagnostic work-up for targeted therapies in conjunction with dermatologists are favoured.
