Neoplastic cells frequently have an increased number of transferrin receptors. Coupling transferrin to an anti-neoplastic drug has the potential to overcome multidrug resistance (MDR). The purpose of this study was to examine the distribution and action of doxorubicin-transferrin conjugate (DOXTRF) in a leukaemia cell line (HL60), a multidrug-resistant leukaemia cell line (HL60ADR) and a normal tissue cell line (human fibroblasts). The intracellular accumulation of DOX and DOX-TRF was monitored by direct fluorescence. More DOX-TRF than free DOX was delivered to the tumour cells, and consecutively the levels of DNA double-strand breaks and apoptosis increased even in the multidrug-resistant cell line. In the normal tissue cell line, DOX-TRF did not accumulate, and therefore, the levels of DNA double-strand breaks and apoptosis did not increase. Cell viability was determined using the MTT assay. The IC50 for DOX-TRF was lower than the IC50 value for the free drug in both leukaemia cell lines. The IC50 values for the HL60 cells were 0.08 μM for DOX and 0.02 μM for DOX-TRF. The IC50 values for HL60ADR cells were 7 μM for DOX and 0.035 μM for DOX-TRF. In conclusion, DOX-TRF was able to overcome MDR in the leukaemia cell lines while having only a very limited effect on normal tissue cells.

Анализ 273 пар баранчиков-близнецов показал, что генотип одного из близнецов яа зависит от генотипа другого. Отношения между гомои гетерозиготами, а также между близнецами одинакового генотипа и различного генотипа в общем не отличались существенно от ожидаемых теоретически.

Acta physiol, pol., 1990, 41 (2): 166-166. We investigated iron metabolism in 47 women with thyrotoxic Graves’ disease. Serum iron, ferritin, transferin, triiodothyronine and thyroxine concentrations were RIA measured before and after methimazole treatment when patients became euthyroid. The control group consisted of 52 healthy women. We noted that serum ferritin levels and the ferritin to transferrin ration were significantly lower while the iron to ferritin ratio was higher in patients before and after methimazole therapy. Iron concentration as well as the iron to transferrin and the iron to thyroid hormone ratios were decreased only before treatment.

Protein polymorphism in 767 yellow-necked mice Apodemus flavicollis fMelchior, 1834), was studied in spring and autumn during five years in the Białowieża National Park, Eastern Poland. Two peaks and two declines of population number were observed, and population density varied from 3 to 63 inds/ha. Twenty three loci of proteins were studied, 4 of them were polymorphic; and mean heterozygosity of the studied population was H = 0.057, The greatest variability was observed in the transferrin locus and 4 alleles (7>/a, Trfb, Trfc, and Trfd) were described. The frequency of the Trf" allele and Trf /Trf" homozygotes was negatively correlated with population density in autumn, whereas the frequency of the Trfc allele and TrfaITrfc heterozygotes was positively correlated with population density in autumn. The frequency of heterozygotes was higher than the frequency of homozygotes during each spring. Significant excess of Trf"/Trfc heterozygotes, compared to the values expected from the Hardy-Weinberg ratio, was observed in autumn 1983 and spring 1984, 1986, and 1987. Natural selection may be an important force in maintenance of the transferrin polymorphism in A. flavicollis. It is suggested that heterozygotes survive better than homozygotes during winter and at high population densities. It is also supposed that non-selective forces influence on the Trf allele frequency changes in the studied population of A. flavicollis.

Płodność świń zróżnicowanych typem transferyny (Tf) analizowano na podstawie wyników reprodukcyjnych jednego z gospodarstw zlokalizowanego na terenie woj. olsztyńskiego. W pierwszym etapie badań u 222 loch i 21 knurów rasy wielka biała polska - wbp, określono typ Tf w surowicy krwi metodą elektroforezy w żelu skrobiowym. Ustalono liczbę żywo urodzonego potomstwa w 960 miotach (tj. w 222 - pierwszych i 738 - kolejnych od II do VIII włącznie) po rodzicach o genotypie Tf: AA, BB, AB, kojarzonych w różnych genotypowych układach Tf. Uzyskane wyniki wykazały istotny wpływ typu Tf rodziców na liczbę rodzących się prosiąt w miotach. Zbliżoną liczebnością charakteryzowały się mioty po obojgu rodzicach AA, AB oraz parach AA x AB i AA x BB (odpowiednio: 9.6; 9.4; 9.4 i 9.3 prosięcia w miocie). Mniej liczne były mioty par BB x BB i BB x AB (odpowiednio: 8.3 i 8.9 prosięcia w miocie). W celu wyjaśnienia niekorzystnych efektów reprodukcyjnych par BB x BB i AB x BB, w drugiej części badań przeanalizowano mechanizm segregacji alleli Tf determinujących genotypy potomstwa. Analizą objęto całe mioty loch wieloródek (II - V mioty) o określonych genotypach potomstwa i ich rodziców (wyłącznie z żywo urodzonymi prosiętami, ewentualnie z jednym martwo urodzonym). W obrębie rasy wbp przeanalizowano 60 miotów rodziców kojarzonych z knurami (n = 6) w następujących układach Tf: ♀ AA x ♂ AB (7 miotów, z których uzyskano 56 prosiąt), ♀ AB x ♂ AB (32 mioty - 335 prosiąt), ♀ BB х ♂ AB (14 miotów - 126 prosiąt) i ♀AB x ♂ BB (7 miotów - 78 prosiąt). Po lochach wbp (n = 31) o genotypie Tf AB kojarzonych z knurami (n = 6) rasy polska biała zwisłoucha - pbz ♂ Tf BB, uzyskano 31 miotów, a w nich 318 prosiąt. Otrzymane wyniki wskazały na niesymetryczną segregację alleli w układzie Tf. Efektem tego zjawiska był znaczny niedobór prosiąt o genotypie Tf BB zarówno w potomstwie czysto rasowym, jak i mieszańcowym, zwłaszcza gdy matka nie była homozygotą BB, lecz heterozygotą AB.

На основании анализа трех полиформных систем белков ( Hb ,Tf и CA), рассматривая частоту аллелей, коэффициент гомозиготности, коэффициент „чистопородности", коэффициент сродственности и генетическую дистанцию, можно говорить о существенных генетических различиях между сравниваемыми четырьмя популяциями овец: мериносом, низинной овцой и овцой разновидности Желязна.
