Endometrial cancer (EC) is second only to cervical carcinoma among the most commonly diagnosed malignant tumours of the female reproductive system. The available literature provides evidence for the involvement of 32 genes in the hereditary incidence of EC. The physiological markers of EC and coexisting diet-dependent maladies include antioxidative system disorders but also progressing inflammation; hence, the main forms of prophylaxis and pharmacotherapy ought to include a diet rich in substances aiding the organism’s response to this type of disorder, with a particular focus on ones suitable for lifelong consumption. Tea polyphenols satisfy those requirements due to their proven antioxidative, anti-inflammatory, anti-obesogenic, and antidiabetic properties. Practitioners ought to consider promoting tea consumption among individuals genetically predisposed for EC, particularly given its low cost, accessibility, confirmed health benefits, and above all, suitability for long-term consumption regardless of the patient’s age. The aim of this paper is to analyse the potential usability of tea as an element of prophylaxis and pharmacotherapy support in EC patients. The analysis is based on information available from worldwide literature published in the last 15 years.

Altogether, the p14(ARF) protein is expressed in more than half of the primary ECs and metastatic lesions analyzed and is associated with the transtubal dissemination of the primary tumor. The pattern of the p14(ARF) expression is not associated with the alterations of other TP53 pathway members in advanced-stage human ECs.

Loss of heterozygosity (LOH) is implicated in the initiation and progression of various human neoplasia, and is observed in both early or in advanced-stage human cancers. The current study was aimed at investigating the frequency of LOH TP53 in human endometrial carcinoma (EC) metastases. LOH was analyzed using 3 intragenic polymorphisms in 38 primary ECs and corresponding metastatic lesions. Allelic loss at intron 1 was detected in 14 out of 38 (37%) primary carcinomas and in 11 out of 38 (29%) metastatic lesions. LOH at intron 1 in primary and metastatic tumors was concomitantly noted in 8 out of 38 (21%) cases. LOH at intron 4 was seen in 46% (17 out of 37) primary ECs and in 35% (13 out of 37) metastatic lesions. LOH at intron 4 in primary tumor/metastasis was concomitantly demonstrated in 27% (10 out of 33) cases. Allelic loss at exon 4 was detected in 5 out of 33 (15%) primary ECs and in one out of 33 (3%) corresponding metastases. Coexistence of LOH TP53 in primary ECs with metastases at intron 1 and intron 4 was observed in three out of 33 (9%) cases. Correlation between allelic loss at intron 1 in primary ECs and corresponding metastases was found (R = 0.475, p = 0.003). Moreover, there was correlation between LOH at intron 1 in metastastic ECs and allelic imbalance at intron 4 in primary uterine tumors (R = 0.416, p = 0.01). There was a relationship between LOH at intron 4 in primary ECs and corresponding metastatic lesions (R = 0.457, p = 0.004). LOH TP53 at intron 4 correlated with the presence of the neoplasm in the uterine cervix (R = 0.319, p = 0.049), and with the non-endometrioid type of primary tumor (R = 0.371, p = 0.024). There was a significant correlation between exon 4 LOH and patient age (less or equal to 50 years and above this age; R = -0.375, p = 0.032). p53 overexpression was present in thirteen out of 38 (34%) cases, both in primary ECs and in metastatic lesions. Overexpression of p53 was higher in non-endometrioid ECs (three out of 5; 60%) than in endometrioid-type uterine tumors (ten out of 33; 30.3%; p = 0.315). p53 overexpression correlated with the presence of cancer in the lumen of fallopian tube(s) (R = 0.032, p = 0.046), and with allelic loss at intron 1 in primary ECs (R = 0.599, p = 0.0001). In conclusion, LOH occurs not only in primary uterine tumors but also in corresponding metastases, with the higher incidence being reported at intron 4 of the TP53. A significant link existed between LOH TP53 at intron 1 and p53 overexpression in primary ECs, but not in the corresponding metastatic lesions.

The aim of the study was to evaluate physiological changes in hematological and biochemical parameters in mares in perinatal period. Blood samples were collected from 24 pregnant Polish Konik breed mares which were divided into two groups. The first group (Group -I, n=12) comprised mares living in the wild, in the reserve. The second group (Group -II, n=12) consisted of mares kept in stables. The blood was collected 2 weeks prior to the parturition, then 24 hours after the delivery, and then at the 7th and 21st day after foaling. When comparing the two groups before the parturition, no significant differences in terms of WBC, RBC, and Hb were found, however, there was a significant difference in MCV, MCH, LYM, NEU and SEG NEU (p≤0.05). In Group II, 24 hours after the parturition and at the 21st day after foaling, a significant raise in WBC, NEU and SEG NEU (p≤0.05) was detected. No significant differences in serum concentrations of proteins such as TP, Alb or Glb were observed. As to acute phase proteins, significant rise in SAA and Hp (p≤0.05) was found in the two examined groups 24 hours after the parturition. Yet, this rise remained within physiological range. The study revealed a certain degree of fluctuations in hematological parameters, in serum concentrations of acute-phase proteins and total proteins in the mares in the perinatal period. However, these changes remained still within physiological ranges and thus they do not indicate potential susceptibility to disorders of perinatal period.
