Abstract
Cofilin-1 (CFL1), a small protein of 18 kDa, has been studied as a biomarker due to its involvement in tumor cell migration and invasion. Our aim was to evaluate CFL1 as an indicator of malignancy and aggressiveness in sputum samples. CFL1 was analyzed by ELISA immunoassay in the sputum of 73 lung cancer patients, 13 cancer-free patients, and 6 healthy volunteers. Statistical analyses included ANOVA, ROC curves, Spearman correlation, and logistic regression. Sputum CFL1 levels were increased in cancer patients compared to cancer-free patients and volunteers (P<0.05). High expression of sputum CFL1 was correlated to T4 stage (P=0.01) and N stage (P=0.03), tobacco history (P=0.01), and squamous cell carcinoma histologic type (P=0.04). The accuracy of sputum CFL1 in discriminating cancer patients from cancer-free patients and healthy volunteers were 0.78 and 0.69, respectively. CFL1 at a cut-off value of 415.25 pg/mL showed sensitivity/specificity of 0.80/0.70 in differentiating between healthy volunteers and cancer patients. Sputum CFL1 was also able to identify cancer-free patients from patients with lung cancer. The AUC was 0.70 and, at a cut-off point ≥662.63 pg/mL, we obtained 60% sensitivity and 54% specificity. Logistic regression analysis controlled for tobacco history, histologic types, and N stage showed that cancer cell-associated CFL1 was an independent predictor of death. Smoker patients with squamous cell carcinoma, lymph node metastasis and sputum CFL1>1.475 pg/mL showed augmented chance of death, suggesting lung cancer aggressiveness. CFL1 presented diagnostic value in detecting lung cancer and was associated to tumor aggressiveness.

Abstract
The antioxidant effects of Caryocar brasiliense Camb, commonly known
as the pequi fruit, have not been evaluated to determine their protective effects
against oxidative damage in lung carcinogenesis. In the present study, we evaluated
the role of pequi fruit against urethane-induced DNA damage and oxidative stress in
forty 8-12 week old male BALB/C mice. An in vivo comet assay was
performed to assess DNA damage in lung tissues and changes in lipid peroxidation and
redox cycle antioxidants were monitored for oxidative stress. Prior supplementation
with pequi oil or its extract (15 µL, 60 days) significantly reduced urethane-induced
oxidative stress. A protective effect against DNA damage was associated with the
modulation of lipid peroxidation and low protein and gene expression of nitric oxide
synthase. These findings suggest that the intake of pequi fruit might protect against
in vivo genotoxicity and oxidative stress.

Abstract
Hyaluronan (HA) shows promise for detecting cancerous change in pleural effusion and
urine. However, there is uncertainty about the localization of HA in tumor tissue and
its relationship with different histological types and other components of the
extracellular matrix, such as angiogenesis. We evaluated the association between HA
and degree of malignancy through expression in lung tumor tissue and sputum. Tumoral
tissue had significantly increased HA compared to normal tissue. Strong HA staining
intensity associated with cancer cells was significant in squamous cell carcinoma
compared to adenocarcinoma and large cell carcinoma. A significant direct association
was found between tumors with a high percentage of HA and MVD (microvessel density)
in tumoral stroma. Similarly significant was the direct association between N1 tumors
and high levels of HA in cancer cells. Cox multivariate analysis showed significant
association between better survival and low HA. HA increased in sputum from lung
cancer patients compared to cancer-free and healthy volunteers and a significant
correlation was found between HA in sputum and HA in cancer tissue. Localization of
HA in tumor tissue was related to malignancy and reflected in sputum, making this an
emerging factor for an important diagnostic procedure in patients suspected to have
lung cancer. Further study in additional patients in a randomized prospective trial
is required to finalize these results and to validate our quantitative assessment of
HA, as well as to couple it to gold standard sputum cytology.

Abstract
Limitations on tissue proliferation capacity determined by telomerase/apoptosis
balance have been implicated in pathogenesis of idiopathic pulmonary fibrosis. In
addition, collagen V shows promise as an inductor of apoptosis. We evaluated the
quantitative relationship between the telomerase/apoptosis index, collagen V
synthesis, and epithelial/fibroblast replication in mice exposed to butylated
hydroxytoluene (BHT) at high oxygen concentration. Two groups of mice were analyzed:
20 mice received BHT, and 10 control mice received corn oil. Telomerase expression,
apoptosis, collagen I, III, and V fibers, and hydroxyproline were evaluated by
immunohistochemistry, in situ detection of apoptosis, electron
microscopy, immunofluorescence, and histomorphometry. Electron microscopy confirmed
the presence of increased alveolar epithelial cells type 1 (AEC1) in apoptosis.
Immunostaining showed increased nuclear expression of telomerase in AEC type 2 (AEC2)
between normal and chronic scarring areas of usual interstitial pneumonia (UIP).
Control lungs and normal areas from UIP lungs showed weak green birefringence of type
I and III collagens in the alveolar wall and type V collagen in the basement membrane
of alveolar capillaries. The increase in collagen V was greater than collagens I and
III in scarring areas of UIP. A significant direct association was found between
collagen V and AEC2 apoptosis. We concluded that telomerase, collagen V fiber
density, and apoptosis evaluation in experimental UIP offers the potential to control
reepithelization of alveolar septa and fibroblast proliferation. Strategies aimed at
preventing high rates of collagen V synthesis, or local responses to high rates of
cell apoptosis, may have a significant impact in pulmonary fibrosis.
